|
||||
## option they want to enable, and to set the specific value of that option.
|
||||
##
|
||||
## WARNING: Setting the following combination of parameters will set a
|
||||
## permanent bit within the SOC and your warranty is void.
|
||||
## over_voltage>0, and at least one of the following:
|
||||
## force_turbo=1
|

Subject: [PATCH] ARM: dts: bcm283x: Define standard pinctrl groups in the gpio
|
||||
node.
|
||||
|
||||
The BCM2835-ARM-Peripherals.pdf documentation specifies what the
|
||||
function selects do for the pins, and there are a bunch of obvious
|
||||
groupings to be made. With these created, we'll be able to replace
|
||||
bcm2835-rpi.dtsi's main "set all of these pins to alt0" with
|
||||
references to specific groups we want enabled.
|
||||
|
||||
Also add pinctrl groups for emmc and sdhost.
|
||||
|
||||
Based on patches by Eric Anholt, with fixups by Gerd Hoffmann.

Changelog:
|
||||
V1 -> V5: generic settings is shared in bcm283x.dtsi, but disabled
|
||||
moved the compatible string to the SOC specific dtsi
|
||||
for arm and arm64
|

V5 -> V6: fix remove 0x prefix from thermal@0x7e212000
|
||||
|
||||
Note: there is no arm/boot/dts/bcm2837.dtsi as of now,
|
||||
so the 32-bit rpi3 dt is not modified.

Subject: [PATCH] ARM: bcm2835: Add names for the Raspberry Pi GPIO lines
|
||||
|
||||
The idea is to give useful names to GPIO lines that an implementer
|
||||
will be using from userspace, e.g. for maker type projects. These are
|
||||
user-visible using tools/gpio/lsgpio.c
|
||||
|
||||
v2: Major rewrite by anholt: Flatten each GPIO line to a line in the
|
||||
file for better diffing, prefix all expansion header pins with
|
||||
"P<number>" or "P5HEADER_P<number>" and drop the mostly-unused
|
||||
GPIO_GEN<smallnumber> names in favor of GPIO<socgpionumber>, fix
|
||||
extra '[]' on a couple of lines, fix locations of SD_CARD_DETECT,
|
||||
CAM_GPIO and STATUS_LED, fix HDMI_HPD polarities, rewrite A+ using
|
||||
unreleased schematics.
|
||||
|
||||
v3: More changes by anholt: Drop P<number> / P5HEADER<number>
|
||||
prefixes. I had been skeptical about adding them, and was
|
||||
convinced to drop them by Gottfried (who probably has more
|
||||
experience with GPIOs in educational contexts than the rest of
|
||||
us). Also drop [] brackets for "is pinmuxed", which didn't seem
|
||||
to clarify, and were ambiguous for things like the SPI_*-labeled
|
||||
pins which may or may not actually be pinmuxed to SPI.
|
||||
|
||||
v4: Rename B+'s SDA0/SCL0 to match the other boards, despite the
|
||||
naming on its schematic.

Subject: [PATCH] ARM: bcm2835: Fix names for the Raspberry Pi GPIO lines
|
||||
|
||||
There are some differences between the schematics and the official firmware
|
||||
DTS [1]. So based on these additional information the following has been
|
||||
changed:
|
||||
|
||||
* use consistent "CAM_GPIO1" for camera LED
|
||||
* use consistent "CAM_GPIO0" for camera shutdown
|
||||
* add "USB_LIMIT" for USB current limit (0=600mA, 1=1200mA)

This adds the GPIO names for the Raspberry Pi Zero. The GPIO lines
|
||||
of the RPi Zero are almost identical to the Model A+ except:
|
||||
|
||||
* GPIO 35, 38, 40 and 45 are not connected
|
||||
* Status LED is active low

Subject: [PATCH] irq-bcm2836: Prevent spurious interrupts, and trap them early
|
||||
|
||||
The old arch-specific IRQ macros included a dsb to ensure the
|
||||
write to clear the mailbox interrupt completed before returning
|
||||
from the interrupt. The BCM2836 irqchip driver needs the same
|
||||
precaution to avoid spurious interrupts.
|
||||
|
||||
Spurious interrupts are still possible for other reasons,
|
||||
though, so trap them early.

Add a duplicate irq range with an offset on the hwirq's so the

Subject: [PATCH] pinctrl-bcm2835: Fix interrupt handling for GPIOs 28-31 and
|
||||
46-53
|
||||
|
||||
Contrary to the documentation, the BCM2835 GPIO controller actually has
|
||||
four interrupt lines - one each for the three IRQ groups and one common. Rather
|
||||
confusingly, the GPIO interrupt groups don't correspond directly with the GPIO
|
||||
control banks. Instead, GPIOs 0-27 generate IRQ GPIO0, 28-45 GPIO1 and
|
||||
46-53 GPIO2.
|
||||
|
||||
Awkwardly, the GPIOS for IRQ GPIO1 straddle two 32-entry GPIO banks, so it is
|
||||
cleaner to split out a function to process the interrupts for a single GPIO
|
||||
bank.
|
||||
|
||||
This bug has only just been observed because GPIOs above 27 can only be
|
||||
accessed on an old Raspberry Pi with the optional P5 header fitted, where
|
||||
the pins are often used for I2S instead.

Although the GPIO controller can generate three interrupts (four counting
|
||||
the common one), the device tree files currently only specify two. In the
|
||||
absence of the third, simply don't register that interrupt (as opposed to
|
||||
registering 0), which has the effect of making it impossible to generate
|
||||
interrupts for GPIOs 46-53 which, since they share pins with the SD card
|
||||
interface, is unlikely to be a problem.

Subject: [PATCH] spi-bcm2835: Support pin groups other than 7-11
|
||||
|
||||
The spi-bcm2835 driver automatically uses GPIO chip-selects due to
|
||||
some unreliability of the native ones. In doing so it chooses the
|
||||
same pins as the native chip-selects would use, but the existing
|
||||
code always uses pins 7 and 8, wherever the SPI function is mapped.
|
||||
|
||||
Search the pinctrl group assigned to the driver for pins that
|
||||
correspond to native chip-selects, and use those for GPIO chip-
|
||||
selects.

The VideoCore bootloader passes in Serial number and
|
||||
Revision number through Device Tree. Make these available to
|
||||
userspace through /proc/cpuinfo.
|
||||
|
||||
Mainline status:
|
||||
|
||||
There is a commit in linux-next that standardize passing the serial
|
||||
number through Device Tree (string: /serial-number):
|
||||
ARM: 8355/1: arch: Show the serial number from devicetree in cpuinfo
|
||||
|
||||
There was an attempt to do the same with the revision number, but it
|
||||
didn't get in:

Load driver early since at least bcm2708_fb doesn't support deferred
|

probing and even if it did, we don't want the video driver deferred.

Support the legacy DMA API which is needed by bcm2708_fb.

Don't mask out channel 2.

Subject: [PATCH] clk: bcm2835: Mark GPIO clocks enabled at boot as critical.
|
||||
|
||||
These divide off of PLLD_PER and are used for the ethernet and wifi
|
||||
PHYs source PLLs. Neither of them is currently represented by a phy
|
||||
device that would grab the clock for us.
|
||||
|
||||
This keeps other drivers from killing the networking PHYs when they
|
||||
disable their own clocks and trigger PLLD_PER's refcount going to 0.
|
||||
|
||||
v2: Skip marking as critical if they aren't on at boot.

|

The Raspberry Pi firmware looks at the RSTS register to know which
|
||||
partition to boot from. The reboot syscall command
|
||||
LINUX_REBOOT_CMD_RESTART2 supports passing in a string argument.
|
||||
|
||||
Add support for passing in a partition number 0..63 to boot from.
|
||||
Partition 63 is a special partiton indicating halt.
|
||||
If the partition doesn't exist, the firmware falls back to partition 0.

Currently it only supports cyclic DMA.

Mirror bcm2835-dma.c commit 9eba5536a7434c69d8c185d4bd1c70734d92287d:
|
||||
chancnt is already filled by dma_async_device_register, which uses the channel
|
||||
list to know how much channels there is.
|
||||
|
||||
Since it's already filled, we can safely remove it from the drivers' probe
|
||||
function.

dmaengine: bcm2708: overwrite dreq only if it is not set
|
||||
|
||||
dreq is set when the DMA channel is fetched from Device Tree.
|
||||
slave_id is set using dmaengine_slave_config().
|
||||
Only overwrite dreq with slave_id if it is not set.
|
||||
|
||||
dreq/slave_id in the cyclic DMA case is not touched, because I don't
|
||||
have hardware to test with.

dmaengine: bcm2708: Merge with arch dma.c driver and disable dma.c
|
||||
|
||||
Merge the legacy DMA API driver with bcm2708-dmaengine.
|
||||
This is done so we can use bcm2708_fb on ARCH_BCM2835 (mailbox
|
||||
driver is also needed).
|
||||
|
||||
Changes to the dma.c code:
|
||||
- Use BIT() macro.
|
||||
- Cutdown some comments to one line.
|
||||
- Add mutex to vc_dmaman and use this, since the dev lock is locked
|
||||
during probing of the engine part.
|
||||
- Add global g_dmaman variable since drvdata is used by the engine part.
|
||||
- Restructure for readability:
|
||||
vc_dmaman_chan_alloc()
|
||||
vc_dmaman_chan_free()
|
||||
bcm_dma_chan_free()
|
||||
- Restructure bcm_dma_chan_alloc() to simplify error handling.
|
||||
- Use device irq resources instead of hardcoded bcm_dma_irqs table.
|
||||
- Remove dev_dmaman_register() and code it directly.
|
||||
- Remove dev_dmaman_deregister() and code it directly.
|
||||
- Simplify bcm_dmaman_probe() using devm_* functions.
|
||||
- Get dmachans from DT if available.
|
||||
- Keep 'dma.dmachans' module argument name for backwards compatibility.
|
||||
|
||||
Make it available on ARCH_BCM2835 as well.

dmaengine: bcm2708: set residue_granularity field
|
||||
|
||||
bcm2708-dmaengine supports residue reporting at burst level
|
||||
but didn't report this via the residue_granularity field.
|
||||
|
||||
Without this field set properly we get playback issues with I2S cards.
|
||||
|
||||
dmaengine: bcm2708-dmaengine: Fix memory leak when stopping a running transfer
|
||||
|
||||
bcm2708-dmaengine: Use more DMA channels (but not 12)
|
||||
|
||||
1) Only the bcm2708_fb drivers uses the legacy DMA API, and
|
||||
it requires a BULK-capable channel, so all other types
|
||||
(FAST, NORMAL and LITE) can be made available to the regular
|
||||
DMA API.
|
||||
|
||||
2) DMA channels 11-14 share an interrupt. The driver can't
|
||||
handle this, so don't use channels 12-14 (12 was used, probably
|
||||
because it appears to have an interrupt, but in reality that
|
||||
interrupt is for activity on ANY channel). This may explain
|
||||
a lockup encountered when running out of DMA channels.
|
||||
|
||||
The combined effect of this patch is to leave 7 DMA channels
|
||||
available + channel 0 for bcm2708_fb via the legacy API.
|
||||
|
||||

dmaengine: bcm2708: Make legacy API available for bcm2835-dma
|
||||
|
||||
bcm2708_fb uses the legacy DMA API, so in order to start using
|
||||
bcm2835-dma, bcm2835-dma has to support the legacy API. Make this
|
||||
possible by exporting bcm_dmaman_probe() and bcm_dmaman_remove().

Subject: [PATCH] mmc: Add MMC_QUIRK_ERASE_BROKEN for some cards
|
||||
|
||||
Some SD cards have been found that corrupt data when small blocks
|
||||
are erased. Add a quirk to indicate that ERASE should not be used,
|
||||
and set it for cards of that type.

||||
mmc: Add card_quirks module parameter, log quirks
|
||||
|
||||
Use mmc_block.card_quirks to override the quirks for all SD or MMC
|
||||
cards. The value is a bitfield using the bit positions defined in
|
||||
include/linux/mmc/card.h. If the module parameter is placed in the
|
||||
kernel command line (or bootargs) stored on the card then, assuming the
|
||||
device only has one SD card interface, the override effectively becomes
|
||||
card-specific.

+* BCM2835 SMI NAND flash
|
||||
+
|
||||
+This driver is a shim between the BCM2835 SMI driver (SMI is a peripheral for
|
||||
+talking to parallel register interfaces) and Linux's MTD layer.
|
||||
+
|
||||
+Required properties:
|
||||
+- compatible: "brcm,bcm2835-smi-nand"
|
||||
+- status: "okay"
|
||||
+
|
||||
+Optional properties:
|
||||
+- partition@n, where n is an integer from a consecutive sequence starting at 0
|
||||
+ - Difficult to store partition table on NAND device - normally put it
|
||||
+ in the source code, kernel bootparams, or device tree (the best way!)
|
||||
+ - Sub-properties:
|
||||
+ - label: the partition name, as shown by mtdinfo /dev/mtd*
|
||||
+ - reg: the size and offset of this partition.
|
||||
+ - (optional) read-only: an empty property flagging as read only
|
||||
+
|
||||
+Example:
|
||||
+
|
||||
+nand: flash@0 {
|
||||
+ compatible = "brcm,bcm2835-smi-nand";
|
||||
+ status = "okay";
|
||||
+
|
||||
+ partition@0 {
|
||||
+ label = "stage2";
|
||||
+ // 128k
|
||||
+ reg = <0 0x20000>;
|
||||
+ read-only;
|
||||
+ };
|
||||
+ partition@1 {
|
||||
+ label = "firmware";
|
||||
+ // 16M
|
||||
+ reg = <0x20000 0x1000000>;
|
||||
+ read-only;
|
||||
+ };
|
||||
+ partition@2 {
|
||||
+ label = "root";

||||
+ // 2G
|
||||
+ reg = <0x1020000 0x80000000>;

Subject: [PATCH] lirc: added support for RaspberryPi GPIO
|
||||
|
||||
lirc_rpi: Use read_current_timer to determine transmitter delay. Thanks to jjmz and others
|
||||
See: https://github.com/raspberrypi/linux/issues/525
|
||||
|
||||
lirc: Remove restriction on gpio pins that can be used with lirc
|
||||
|
||||
Compute Module, for example could use different pins
|
||||
|
||||
lirc_rpi: Add parameter to specify input pin pull
|
||||
|
||||
Depending on the connected IR circuitry it might be desirable to change the
|
||||
gpios internal pull from it pull-down default behaviour. Add a module
|
||||
parameter to allow the user to set it explicitly.
|
||||
|
||||
Signed-off-by: Julian Scheel <julian@jusst.de>
|
||||
|
||||
lirc-rpi: Use the higher-level irq control functions
|
||||
|
||||
This module used to access the irq_chip methods of the
|
||||
gpio controller directly, rather than going through the
|
||||
standard enable_irq/irq_set_irq_type functions. This
|
||||
caused problems on pinctrl-bcm2835 which only implements
|
||||
the irq_enable/disable methods and not irq_unmask/mask.
|
||||
|
||||
lirc-rpi: Correct the interrupt usage
|
||||
|
||||
1) Correct the use of enable_irq (i.e. don't call it so often)
|
||||
2) Correct the shutdown sequence.
|
||||
3) Avoid a bcm2708_gpio driver quirk by setting the irq flags earlier
|
||||
|
||||
lirc-rpi: use getnstimeofday instead of read_current_timer
|
||||
|
||||
read_current_timer isn't guaranteed to return values in
|
||||
microseconds, and indeed it doesn't on a Pi2.
|
||||
|
||||
Issue: linux#827
|
||||
|
||||
lirc-rpi: Add device tree support, and a suitable overlay
|
||||
|
||||
The overlay supports DT parameters that match the old module
|
||||
parameters, except that gpio_in_pull should be set using the
|
||||
strings "up", "down" or "off".
|
||||
|
||||
lirc-rpi: Also support pinctrl-bcm2835 in non-DT mode
|
||||
|
||||
fix auto-sense in lirc_rpi driver
|
||||
|
||||
On a Raspberry Pi 2, the lirc_rpi driver might receive spurious
|
||||
interrupts and change it's low-active / high-active setting.
|
||||
When this happens, the IR remote control stops working.
|
||||
|
||||
This patch disables this auto-detection if the 'sense' parameter
|
||||
was set in the device tree, making the driver robust to such
|
||||
spurious interrupts.

i2c-bcm2708: fixed baudrate
|
||||
|
||||
Fixed issue where the wrong CDIV value was set for baudrates below 3815 Hz (for 250MHz bus clock).
|
||||
In that case the computed CDIV value was more than 0xffff. However the CDIV register width is only 16 bits.
|
||||
This resulted in incorrect setting of CDIV and higher baudrate than intended.
|
||||
Example: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0x1704 -> 42430Hz
|
||||
After correction: 3500Hz -> CDIV=0x11704 -> CDIV(16bit)=0xffff -> 3815Hz
|
||||
The correct baudrate is shown in the log after the cdiv > 0xffff correction.
|
||||
|
||||
Perform I2C combined transactions when possible
|
||||
|
||||
Perform I2C combined transactions whenever possible, within the
|
||||
restrictions of the Broadcomm Serial Controller.
|
||||
|
||||
Disable DONE interrupt during TA poll
|
||||
|
||||
Prevent interrupt from being triggered if poll is missed and transfer
|
||||
starts and finishes.
|
||||
|
||||
i2c: Make combined transactions optional and disabled by default
|
||||
|
||||
i2c: bcm2708: add device tree support
|
||||
|
||||
Add DT support to driver and add to .dtsi file.
|
||||
Setup pins in .dts file.
|
||||
i2c is disabled by default.

bcm2708: don't register i2c controllers when using DT
|
||||
|
||||
The devices for the i2c controllers are in the Device Tree.
|
||||
Only register devices when not using DT.
|
||||
|
||||
Signed-off-by: Noralf Tronnes <notro@tronnes.org>
|
||||
|
||||
I2C: Only register the I2C device for the current board revision
|
||||
|
||||
i2c_bcm2708: Fix clock reference counting
|
||||
|
||||
Fix grabbing lock from atomic context in i2c driver
|
||||
|
||||
2 main changes:
|
||||
- check for timeouts in the bcm2708_bsc_setup function as indicated by this comment:
|
||||
/* poll for transfer start bit (should only take 1-20 polls) */
|
||||
This implies that the setup function can now fail so account for this everywhere it's called
|
||||
- Removed the clk_get_rate call from inside the setup function as it locks a mutex and that's not ok since we call it from under a spin lock.
|
||||
|
||||
i2c-bcm2708: When using DT, leave the GPIO setup to pinctrl
|
||||
|
||||
i2c-bcm2708: Increase timeouts to allow larger transfers
|
||||
|
||||
Use the timeout value provided by the I2C_TIMEOUT ioctl when waiting
|
||||
for completion. The default timeout is 1 second.
|
||||
|
||||
See: https://github.com/raspberrypi/linux/issues/260
|
||||
|
||||
i2c-bcm2708/BCM270X_DT: Add support for I2C2
|
||||
|
||||
The third I2C bus (I2C2) is normally reserved for HDMI use. Careless
|
||||
use of this bus can break an attached display - use with caution.
|
||||
|
||||
It is recommended to disable accesses by VideoCore by setting
|
||||
hdmi_ignore_edid=1 or hdmi_edid_file=1 in config.txt.
|
||||
|
||||
The interface is disabled by default - enable using the
|
||||
i2c2_iknowwhatimdoing DT parameter.
|
||||
|
||||
bcm2708-spi: Don't use static pin configuration with DT
|
||||
|
||||
Also remove superfluous error checking - the SPI framework ensures the
|
||||
validity of the chip_select value.
|
||||
|
||||
i2c-bcm2708: Remove non-DT support
|
||||
|
||||
Signed-off-by: Noralf Trønnes <noralf@tronnes.org>
|
||||
|
||||
Set the BSC_CLKT clock streching timeout to 35ms as per SMBus specs.
|
||||
|
||||
Fixes i2c_bcm2708: Write to FIFO correctly - v2 (#1574)
|
||||
|
||||
* i2c: fix i2c_bcm2708: Clear FIFO before sending data
|
||||
|
||||
Make sure FIFO gets cleared before trying to send
|
||||
data in case of a repeated start (COMBINED=Y).
|
||||
|
||||
* i2c: fix i2c_bcm2708: Only write to FIFO when not full
|
||||
|
||||
Check if FIFO can accept data before writing.
|
||||
To avoid a peripheral read on the last iteration of a loop,
|
||||
both bcm2708_bsc_fifo_fill and ~drain are changed as well.

Subject: [PATCH] scripts: Add mkknlimg and knlinfo scripts from tools repo
|
||||
|
||||
The Raspberry Pi firmware looks for a trailer on the kernel image to
|
||||
determine whether it was compiled with Device Tree support enabled.
|
||||
If the firmware finds a kernel without this trailer, or which has a
|
||||
trailer indicating that it isn't DT-capable, it disables DT support
|
||||
and reverts to using ATAGs.
|
||||
|
||||
The mkknlimg utility adds that trailer, having first analysed the
|
||||
image to look for signs of DT support and the kernel version string.
|
||||
|
||||
knlinfo displays the contents of the trailer in the given kernel image.
|
||||
|
||||
scripts/mkknlimg: Add support for ARCH_BCM2835
|
||||
|
||||
Add a new trailer field indicating whether this is an ARCH_BCM2835
|
||||
build, as opposed to MACH_BCM2708/9. If the loader finds this flag
|
||||
is set it changes the default base dtb file name from bcm270x...
|
||||
to bcm283y...
|
||||
|
||||
Also update knlinfo to show the status of the field.
|
||||
|
||||
scripts/mkknlimg: Improve ARCH_BCM2835 detection
|
||||
|
||||
The board support code contains sufficient strings to be able to
|
||||
distinguish 2708 vs. 2835 builds, so remove the check for
|
||||
bcm2835-pm-wdt which could exist in either.
|
||||
|
||||
Also, since the canned configuration is no longer built in (it's
|
||||
a module), remove the config string checking.
|
||||
|
||||
See: https://github.com/raspberrypi/linux/issues/1157
|
||||
|
||||
scripts: Multi-platform support for mkknlimg and knlinfo
|
||||
|
||||
The firmware uses tags in the kernel trailer to choose which dtb file
|
||||
to load. Current firmware loads bcm2835-*.dtb if the '283x' tag is true,
|
||||
otherwise it loads bcm270*.dtb. This scheme breaks if an image supports
|
||||
multiple platforms.
|
||||
|
||||
This patch adds '270X' and '283X' tags to indicate support for RPi and
|
||||
upstream platforms, respectively. '283x' (note lower case 'x') is left
|
||||
for old firmware, and is only set if the image only supports upstream
|
||||
builds.
|
||||
|
||||
scripts/mkknlimg: Append a trailer for all input
|
||||
|
||||
Now that the firmware assumes an unsigned kernel is DT-capable, it is
|
||||
helpful to be able to mark a kernel as being non-DT-capable.

mkknlimg: Retain downstream-kernel detection
|
||||
|
||||
With the death of ARCH_BCM2708 and ARCH_BCM2709, a new way is needed to
|
||||
determine if this is a "downstream" build that wants the firmware to
|
||||
load a bcm27xx .dtb. The vc_cma driver is used downstream but not
|
||||
upstream, making vc_cma_init a suitable predicate symbol.

Subject: [PATCH] BCM270x_DT: Add pwr_led, and the required "input" trigger
|
||||
|
||||
The "input" trigger makes the associated GPIO an input. This is to support
|
||||
the Raspberry Pi PWR LED, which is driven by external hardware in normal use.
|
||||
|
||||
N.B. pwr_led is not available on Model A or B boards.
|
||||
|
||||
leds-gpio: Implement the brightness_get method
|
||||
|
||||
The power LED uses some clever logic that means it is driven
|
||||
by a voltage measuring circuit when configured as input, otherwise
|
||||
it is driven by the GPIO output value. This patch wires up the
|
||||
brightness_get method for leds-gpio so that user-space can monitor
|
||||
the LED value via /sys/class/gpio/led1/brightness. Using the input
|
||||
trigger this returns an indication of the system power health,
|
||||
otherwise it is just whatever value the trigger has written most
|
||||
recently.
|
||||
|
||||

Provide an ioctl for userspace applications, but only if this operation

Subject: [PATCH] Speed up console framebuffer imageblit function
|
||||
|
||||
Especially on platforms with a slower CPU but a relatively high
|
||||
framebuffer fill bandwidth, like current ARM devices, the existing
|
||||
console monochrome imageblit function used to draw console text is
|
||||
suboptimal for common pixel depths such as 16bpp and 32bpp. The existing
|
||||
code is quite general and can deal with several pixel depths. By creating
|
||||
special case functions for 16bpp and 32bpp, by far the most common pixel
|
||||
formats used on modern systems, a significant speed-up is attained
|
||||
which can be readily felt on ARM-based devices like the Raspberry Pi
|
||||
and the Allwinner platform, but should help any platform using the
|
||||
fb layer.
|
||||
|
||||
The special case functions allow constant folding, eliminating a number
|
||||
of instructions including divide operations, and allow the use of an
|
||||
unrolled loop, eliminating instructions with a variable shift size,
|
||||
reducing source memory access instructions, and eliminating excessive
|
||||
branching. These unrolled loops also allow much better code optimization
|
||||
by the C compiler. The code that selects which optimized variant is used
|
||||
is also simplified, eliminating integer divide instructions.
|
||||
|
||||
The speed-up, measured by timing 'cat file.txt' in the console, varies
|
||||
between 40% and 70%, when testing on the Raspberry Pi and Allwinner
|
||||
ARM-based platforms, depending on font size and the pixel depth, with
|
||||
the greater benefit for 32bpp.

Subject: [PATCH] gpio-poweroff: Allow it to work on Raspberry Pi
|
||||
|
||||
The Raspberry Pi firmware manages the power-down and reboot
|
||||
process. To do this it installs a pm_power_off handler, causing
|
||||
the gpio-poweroff module to abort the probe function.
|
||||
|
||||
This patch introduces a "force" DT property that overrides that
|
||||
behaviour, and also adds a DT overlay to enable and control it.
|
||||
|
||||
Note that running in an active-low configuration (DT parameter
|
||||
"active_low") requires a custom dt-blob.bin and probably won't
|
||||
allow a reboot without switching off, so an external inversion
|
||||
of the trigger signal may be preferable.
