NAND_ECC_NONE
Use the core's large page OOB layout functions when not reserving any
space for ECC bytes in the OOB layout. Fix ->nand_ooblayout_ecc_lp()

Subject: [PATCH] dmaengine: qcom-bam: Process multiple pending descriptors
The bam dmaengine has a circular FIFO to which we
add hw descriptors that describes the transaction.
The FIFO has space for about 4096 hw descriptors.
Currently we add one descriptor and wait for it to
complete with interrupt and then add the next pending
descriptor. In this way, the FIFO is underutilized
since only one descriptor is processed at a time, although
there is space in FIFO for the BAM to process more.
Instead keep adding descriptors to FIFO till its full,
that allows BAM to continue to work on the next descriptor
immediately after signalling completion interrupt for the
previous descriptor.
Also when the client has not set the DMA_PREP_INTERRUPT for
a descriptor, then do not configure BAM to trigger a interrupt
upon completion of that descriptor. This way we get a interrupt
only for the descriptor for which DMA_PREP_INTERRUPT was
requested and there signal completion of all the previous completed
descriptors. So we still do callbacks for all requested descriptors,
but just that the number of interrupts are reduced.

Subject: [PATCH 5/7] mtd: nand: force drivers to explicitly send READ/PROG
commands
The core currently send the READ0 and SEQIN+PAGEPROG commands in
nand_do_read/write_ops(). This is inconsistent with
->read/write_oob[_raw]() hooks behavior which are expected to send
these commands.
There's already a flag (NAND_ECC_CUSTOM_PAGE_ACCESS) to inform the core
that a specific controller wants to send the READ/SEQIN+PAGEPROG
commands on its own, but it's an opt-in flag, and existing drivers are
unlikely to be updated to pass it.
Moreover, some controllers cannot dissociate the READ/PAGEPROG commands
from the associated data transfer and ECC engine activation, and
developers have to hack things in their ->cmdfunc() implementation to
handle such complex cases, or have to accept the perf penalty of sending
twice the same command.
To address this problem we are planning on adding a new interface which
is passed all information about a NAND operation (including the amount
of data to transfer) and replacing all calls to ->cmdfunc() to calls to
this new ->exec_op() hook. But, in order to do that, we need to have all
->cmdfunc() calls placed near their associated ->read/write_buf/byte()
calls.
Modify the core and relevant drivers to make NAND_ECC_CUSTOM_PAGE_ACCESS
the default case, and remove this flag.

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: [PATCH] pinctrl: msm: fix gpio-hog related boot issues
Sven Eckelmann reported an issue with the current IPQ4019 pinctrl.
Setting up any gpio-hog in the device-tree for his device would
"kill the bootup completely":
| [ 0.477838] msm_serial 78af000.serial: could not find pctldev for node /soc/pinctrl@1000000/serial_pinmux, deferring probe
| [ 0.499828] spi_qup 78b5000.spi: could not find pctldev for node /soc/pinctrl@1000000/spi_0_pinmux, deferring probe
| [ 1.298883] requesting hog GPIO enable USB2 power (chip 1000000.pinctrl, offset 58) failed, -517
| [ 1.299609] gpiochip_add_data: GPIOs 0..99 (1000000.pinctrl) failed to register
| [ 1.308589] ipq4019-pinctrl 1000000.pinctrl: Failed register gpiochip
| [ 1.316586] msm_serial 78af000.serial: could not find pctldev for node /soc/pinctrl@1000000/serial_pinmux, deferring probe
| [ 1.322415] spi_qup 78b5000.spi: could not find pctldev for node /soc/pinctrl@1000000/spi_0_pinmux, deferri
This was also verified on a RT-AC58U (IPQ4018) which would
no longer boot, if a gpio-hog was specified. (Tried forcing
the USB LED PIN (GPIO0) to high.).
The problem is that Pinctrl+GPIO registration is currently
peformed in the following order in pinctrl-msm.c:
1. pinctrl_register()
2. gpiochip_add()
3. gpiochip_add_pin_range()
The actual error code -517 == -EPROBE_DEFER is coming from
pinctrl_get_device_gpio_range(), which is called through:
gpiochip_add
of_gpiochip_add
of_gpiochip_scan_gpios
gpiod_hog
gpiochip_request_own_desc
__gpiod_request
chip->request
gpiochip_generic_request
pinctrl_gpio_request
pinctrl_get_device_gpio_range
pinctrl_get_device_gpio_range() is unable to find any valid
pin ranges, since nothing has been added to the pinctrldev_list yet.
so the range can't be found, and the operation fails with -EPROBE_DEFER.
This patch fixes the issue by adding the "gpio-ranges" property to
the pinctrl device node of all upstream Qcom SoC. The pin ranges are
then added by the gpio core.
In order to remain compatible with older, existing DTs (and ACPI)
a check for the "gpio-ranges" property has been added to
msm_gpio_init(). This prevents the driver of adding the same entry
to the pinctrldev_list twice.

This patch adds a hack that allows UBI's autoattach feature
to work with the custom ASUS UBI_DEV partition name.
This is necessary because the vendor's u-boot doesn't leave
the bootargs / cmdline alone, so the it can't be overwritten
easily otherwise.

Subject: [PATCH] dts: ipq4019: add PHY/switch nodes
This patch adds both the "qcom,ess-switch" and "qcom,ess-psgmii"
nodes which are needed for the ar40xx.c driver to initialize the
switch.

Subject: [PATCH] dts: ipq4019: add ethernet essedma node
This patch adds the device-tree node for the ethernet
interfaces.
Note: The driver isn't anywhere close to be upstream,
so the info might change.

Subject: essedma: Disable TCP segmentation offload for IPv6
It was noticed that the the whole MAC can hang when transferring data from
one ar40xx port (WAN ports) to the CPU and from the CPU back to another
ar40xx port (LAN ports). The CPU was doing only NATing in that process.
Usually, the problem first starts with a simple data corruption:
$ wget https://cdimage.debian.org/debian-cd/current/amd64/iso-cd/debian-10.4.0-amd64-netinst.iso -O /dev/null
...
Connecting to saimei.ftp.acc.umu.se (saimei.ftp.acc.umu.se)|2001:6b0:19::138|:443... connected.
...
Read error at byte 48807936/352321536 (Decryption has failed.). Retrying.
But after a short while, the whole MAC will stop to react. No traffic can
be transported anymore from the CPU port from/to the AR40xx PHY/switch and
the MAC has to be resetted.

Subject: [PATCH 37/38] usb: dwc3: register qca,ipq4019-dwc3 in dwc3-of-simple
For host mode, the dwc3 found in the IPQ4019 can be driven
by the dwc3-of-simple module. It will get more tricky for
OTG since they'll need to enable VBUS and reconfigure the
registers.

Subject: [PATCH] ARM: dts: ipq4019: Add TZ and SMEM reserved regions
The QSEE (trustzone) is started on IPQ4019 before Linux is started.
According to QCA, it is placed in in the the memory region
0x87e80000-0x88000000 and must not be accessed directly. There is an
additional memory region 0x87e00000-0x87E80000 smem which which can be used
for communication with the TZ. The driver for the latter is not yet ready
but it is still not allowed to use this memory region like any other
memory region.
Not reserving this memory region either leads to kernel crashes, kernel
hangs (often during the boot) or bus errors for userspace programs. The
latter happens when a program is using a memory region which is mapped to
these physical memory regions.

There are additional memory regions which have to be initialized first by
Linux. So they are currently not used. We were told by QCA that the
features QSDK uses them for are:
* crash dump feature
- a couple of regions used when 'qca,scm_restart_reason' dt node has the
value 'dload_status' not set to 1
+ apps_bl <0x87000000 0x400000>
+ sbl <0x87400000 0x100000>
+ cnss_debug <0x87400000 0x100000>
+ cpu_context_dump <0x87b00000 0x080000>
- required driver not available in Linux
- safe to remove
* QSEE app execution
- region tz_apps <0x87b80000 0x280000>
- required driver not available in Linux
- safe to remove
* communication with TZ/QSEE
- region smem <0x87b80000 0x280000>
- driver changes not yet upstreamed
- must not be removed because any access can crash kernel/program
* trustzone (QSEE) private memory
- region tz <0x87e80000 0x180000>
- must not be removed because any access can crash kernel/program
The problem with the missing regions was reported in 2016 [1]. So maybe
this change qualifies for a stable@vger.kernel.org submission.

Subject: [PATCH] clk: fix apss cpu overclocking
There's an interaction issue between the clk changes:"
clk: qcom: ipq4019: Add the apss cpu pll divider clock node
clk: qcom: ipq4019: remove fixed clocks and add pll clocks
" and the cpufreq-dt.
cpufreq-dt is now spamming the kernel-log with the following:
[ 1099.190658] cpu cpu0: dev_pm_opp_set_rate: failed to find current OPP
for freq 761142857 (-34)
This only happens on certain devices like the Compex WPJ428
and AVM FritzBox!4040. However, other devices like the Asus
RT-AC58U and Meraki MR33 work just fine.
The issue stem from the fact that all higher CPU-Clocks
are achieved by switching the clock-parent to the P_DDRPLLAPSS
(ddrpllapss). Which is set by Qualcomm's proprietary bootcode
as part of the DDR calibration.
For example, the FB4040 uses 256 MiB Nanya NT5CC128M16IP clocked
at round 533 MHz (ddrpllsdcc = 190285714 Hz).
whereas the 128 MiB Nanya NT5CC64M16GP-DI in the ASUS RT-AC58U is
clocked at a slightly higher 537 MHz ( ddrpllsdcc = 192000000 Hz).
This patch attempts to fix the issue by modifying
clk_cpu_div_round_rate(), clk_cpu_div_set_rate(), clk_cpu_div_recalc_rate()
to use a new qcom_find_freq_close() function, which returns the closest
matching frequency, instead of the next higher. This way, the SoC in
the FB4040 (with its max clock speed of 710.4 MHz) will no longer
try to overclock to 761 MHz.
