ipq806x: add kernel 4.14 support
- Rebased the patches for 4.14
- Dropped spi-qup and 0027, 0028, 0029
clk patches since it's already included
in upstream.
Tested on IPQ AP148 Board:
1) NOR boot and NAND boot
2) Tested USB and PCIe interfaces
3) WDOG test
4) cpu frequency scaling
5) ethernet, 2G and 5G WiFi
6) ubi sysupgrade

Subject: [PATCH 01/69] dtbindings: qcom_adm: Fix channel specifiers
|
||||
|
||||
Original patch from Andy Gross.
|
||||
|
||||
This patch removes the crci information from the dma
|
||||
channel property. At least one client device requires
|
||||
using more than one CRCI value for a channel. This does
|
||||
not match the current binding and the crci information
|
||||
needs to be removed.
|
||||
|
||||
Instead, the client device will provide this information
|
||||
via other means.

Subject: [PATCH 02/69] dmaengine: Add ADM driver
|
||||
|
||||
Original patch by Andy Gross.
|
||||
|
||||
Add the DMA engine driver for the QCOM Application Data Mover (ADM) DMA
|
||||
controller found in the MSM8x60 and IPQ/APQ8064 platforms.
|
||||
|
||||
The ADM supports both memory to memory transactions and memory
|
||||
to/from peripheral device transactions. The controller also provides flow
|
||||
control capabilities for transactions to/from peripheral devices.
|
||||
|
||||
The initial release of this driver supports slave transfers to/from peripherals
|
||||
and also incorporates CRCI (client rate control interface) flow control.

Subject: [PATCH 31/69] mtd: add SMEM parser for QCOM platforms
|
||||
|
||||
On QCOM platforms using MTD devices storage (such as IPQ806x), SMEM is
|
||||
used to store partition layout. This new parser can now be used to read
|
||||
SMEM and use it to register an MTD layout according to its content.

Subject: [PATCH 33/69] ARM: qcom: automatically select PCI_DOMAINS if PCI is
|
||||
enabled
|
||||
|
||||
If multiple PCIe devices are present in the system, the kernel will
|
||||
panic at boot time when trying to scan the PCI buses. This happens on
|
||||
IPQ806x based platforms, which has 3 PCIe ports.
|
||||
|
||||
Enabling this option allows the kernel to assign the pci-domains
|
||||
according to the device-tree content. This allows multiple PCIe
|
||||
controllers to coexist in the system.

|
||||
|
||||
Krait CPUs have a handful of L2 cache controller registers that
|
||||
live behind a cp15 based indirection register. First you program
|
||||
the indirection register (l2cpselr) to point the L2 'window'
|
||||
register (l2cpdr) at what you want to read/write. Then you
|
||||
read/write the 'window' register to do what you want. The
|
||||
l2cpselr register is not banked per-cpu so we must lock around
|
||||
accesses to it to prevent other CPUs from re-pointing l2cpdr
|
||||
underneath us.

We want to reuse the logic in clk-mux.c for other clock drivers
|
||||
that don't use readl as register accessors. Fortunately, there
|
||||
really isn't much to the mux code besides the table indirection
|
||||
and quirk flags if you assume any bit shifting and masking has
|
||||
been done already. Pull that logic out into reusable functions
|
||||
that operate on an optional table and some flags so that other
|
||||
drivers can use the same logic.

|
||||
On some devices (MSM8974 for example), the HFPLLs are
|
||||
instantiated within the Krait processor subsystem as separate
|
||||
register regions. Add a driver for these PLLs so that we can
|
||||
provide HFPLL clocks for use by the system.

|

The Krait clocks are made up of a series of muxes and a divider
|
||||
that choose between a fixed rate clock and dedicated HFPLLs for
|
||||
each CPU. Instead of using mmio accesses to remux parents, the
|
||||
Krait implementation exposes the remux control via cp15
|
||||
registers. Support these clocks.

The ACC and GCC regions present in KPSSv1 contain registers to
|
||||
control clocks and power to each Krait CPU and L2. For CPUfreq
|
||||
purposes probe these devices and expose a mux clock that chooses
|
||||
between PXO and PLL8.

The Krait CPU clocks are made up of a primary mux and secondary
|
||||
mux for each CPU and the L2, controlled via cp15 accessors. For
|
||||
Kraits within KPSSv1 each secondary mux accepts a different aux
|
||||
source, but on KPSSv2 each secondary mux accepts the same aux
|
||||
source.

|
||||
When the Hfplls are reprogrammed during the rate change,
|
||||
the primary muxes which are sourced from the same hfpll
|
||||
for higher frequencies, needs to be switched to the 'safe
|
||||
secondary mux' as the parent for that small window. This
|
||||
is done by registering a clk notifier for the muxes and
|
||||
switching to the safe parent in the PRE_RATE_CHANGE notifier
|
||||
and back to the original parent in the POST_RATE_CHANGE notifier.

The Platform data was removed earlier by,
|
||||
'commit eb96924acddc ("cpufreq: dt: Kill platform-data")'
|
||||
since there were no users at that time.
|
||||
Now this is required when the each of the cpu clocks
|
||||
can be scaled independently, which is the case
|
||||
for krait cores. So reintroduce it.

Subject: [PATCH 47/69] mtd: nand: Create a BBT flag to access bad block
|
||||
markers in raw mode
|
||||
|
||||
Some controllers can access the factory bad block marker from OOB only
|
||||
when they read it in raw mode. When ECC is enabled, these controllers
|
||||
discard reading/writing bad block markers, preventing access to them
|
||||
altogether.
|
||||
|
||||
The bbt driver assumes MTD_OPS_PLACE_OOB when scanning for bad blocks.
|
||||
This results in the nand driver's ecc->read_oob() op to be called, which
|
||||
works with ECC enabled.
|
||||
|
||||
Create a new BBT option flag that tells nand_bbt to force the mode to
|
||||
MTD_OPS_RAW. This would result in the correct op being called for the
|
||||
underlying nand controller driver.

Subject: [PATCH 49/69] PM / OPP: Support adjusting OPP voltages at runtime
|
||||
|
||||
On some SoCs the Adaptive Voltage Scaling (AVS) technique is
|
||||
employed to optimize the operating voltage of a device. At a
|
||||
given frequency, the hardware monitors dynamic factors and either
|
||||
makes a suggestion for how much to adjust a voltage for the
|
||||
current frequency, or it automatically adjusts the voltage
|
||||
without software intervention. Add an API to the OPP library for
|
||||
the former case, so that AVS type devices can update the voltages
|
||||
for an OPP when the hardware determines the voltage should
|
||||
change. The assumption is that drivers like CPUfreq or devfreq
|
||||
will register for the OPP notifiers and adjust the voltage
|
||||
according to suggestions that AVS makes.

Subject: [PATCH 54/69] cpufreq-dt: Handle OPP voltage adjust events
|
||||
|
||||
On some SoCs the Adaptive Voltage Scaling (AVS) technique is
|
||||
employed to optimize the operating voltage of a device. At a
|
||||
given frequency, the hardware monitors dynamic factors and either
|
||||
makes a suggestion for how much to adjust a voltage for the
|
||||
current frequency, or it automatically adjusts the voltage
|
||||
without software intervention.
|
||||
|
||||
In the former case, an AVS driver will call
|
||||
dev_pm_opp_modify_voltage() and update the voltage for the
|
||||
particular OPP the CPUs are using. Add an OPP notifier to
|
||||
cpufreq-dt so that we can adjust the voltage of the CPU when AVS
|
||||
updates the OPP.

Subject: [PATCH 60/69] HACK: arch: arm: force ZRELADDR on arch-qcom
|
||||
|
||||
ARCH_QCOM is using the ARCH_MULTIPLATFORM option, as now recommended
|
||||
on most ARM architectures. This automatically calculate ZRELADDR by
|
||||
masking PHYS_OFFSET with 0xf8000000.
|
||||
|
||||
However, on IPQ806x, the first ~20MB of RAM is reserved for the hardware
|
||||
network accelerators, and the bootloader removes this section from the
|
||||
layout passed from the ATAGS (when used).
|
||||
|
||||
For newer bootloader, when DT is used, this is not a problem, we just
|
||||
reserve this memory in the device tree. But if the bootloader doesn't
|
||||
have DT support, then ATAGS have to be used. In this case, the ARM
|
||||
decompressor will position the kernel in this low mem, which will not be
|
||||
in the RAM section mapped by the bootloader, which means the kernel will
|
||||
freeze in the middle of the boot process trying to map the memory.
|
||||
|
||||
As a work around, this patch allows disabling AUTO_ZRELADDR when
|
||||
ARCH_QCOM is selected. It makes the zImage usage possible on bootloaders
|
||||
which don't support device-tree, which is the case on certain early
|
||||
IPQ806x based designs.

ipq8064: tsens: TSENS driver support for IPQ8064
|
||||
|
||||
Support for IPQ8064 tsens driver. The driver works
|
||||
with the thermal framework. The driver overrides the
|
||||
following fucntionalities:
|
||||
|
||||
1. Get current temperature.
|
||||
2. Get/Set trip temperatures.
|
||||
3. Enabled/Disable trip points.
|
||||
4. ISR for threshold generated interrupt.
|
||||
5. Notify userspace when trip points are hit.

Subject: [PATCH] ipq8064: tsens: Support for configurable interrupts
|
||||
|
||||
Provide support for adding configurable high and
|
||||
configurable low trip temperatures. An interrupts is
|
||||
also triggerred when these trip points are hit. The
|
||||
interrupts can be activated or deactivated from sysfs.
|
||||
This functionality is made available only if
|
||||
CONFIG_THERMAL_WRITABLE_TRIPS is defined.

|
||||
|
||||
The command-line arguments provided by the boot loader will be
|
||||
appended to a new device tree property: bootloader-args.
|
||||
If there is a property "append-rootblock" in DT under /chosen
|
||||
and a root= option in bootloaders command line it will be parsed
|
||||
and added to DT bootargs with the form: <append-rootblock>XX.
|
||||
Only command line ATAG will be processed, the rest of the ATAGs
|
||||
sent by bootloader will be ignored.
|
||||
This is usefull in dual boot systems, to get the current root partition
|
||||
without afecting the rest of the system.

pcie_phy_clk is generated for PCIe controller itself and the
|
||||
GCC controls its branch operation. This error is coming since
|
||||
the assert operations turn off the parent clock before branch
|
||||
clock. Now this patch moves clk_disable_unprepare before assert
|
||||
operations.
|
||||
|
||||
Similarly, during probe function, the clock branch operation
|
||||
should be done after dessert operation. Currently, it does not
|
||||
generate any error since bootloader enables the pcie_phy_clk
|
||||
but the same error is coming during probe, if bootloader
|
||||
disables pcie_phy_clk.

For IPQ806x targets, TZ protects the registers that are used to

configure the routing of interrupts to a target processor.
|

To resolve this, this patch uses scm call to route GPIO interrupts
|

to application processor. Also the scm call interface is changed.

Subject: [PATCH] mtd: nand: add Winbond manufacturer and chip
|
||||
|
||||
This patch adds the W25N01GV NAND to the table of
|
||||
known devices. Without this patch the device gets detected:
|
||||
|
||||
nand: device found, Manufacturer ID: 0xef, Chip ID: 0xaa
|
||||
nand: Unknown NAND 256MiB 1,8V 8-bit
|
||||
nand: 256 MiB, SLC, erase size: 64 KiB, page size: 1024, OOB size : 16
|
||||
|
||||
Whereas the u-boot identifies it as:
|
||||
spi_nand: spi_nand_flash_probe SF NAND ID 00:ef:aa:21
|
||||
SF: Detected W25N01GV with page size 2 KiB, total 128 MiB
|
||||
|
||||
Due to the page size discrepancy, it's impossible to attach
|
||||
ubi volumes on the device.

Subject: mtd: spi-nor: add mx25l25635f with SECT_4K
|
||||
|
||||
This patch fixes an issue with the creation of the
|
||||
ubi volume on the AVM FRITZ!Box 4040. The mx25l25635f
|
||||
and mx25l25635e support SECT_4K which will set the
|
||||
erase size to 4K. This is used by ubi to calculate
|
||||
VID header offsets. Without this, uboot and linux
|
||||
disagrees about the layout and refuse to attach
|
||||
the ubi volume created by the other.
