There are 8 instances of gpio modules in main domain divided into 2 groups:
- Group1: gpio0, gpio2, gpio4, gpio6
- Group2: gpio1, gpio3, gpio5, gpio7
Groups are created to provide protection between two different processor
virtual worlds. There are x gpio lines coming out of each group. Each module
in a group has equal x gpio lines pinned out. There is a top level mux for
selecting the module instance for each pin coming out of group. Exactly
one module can be selected to control the corresponding pin. This muxing
can be controlled along the pad mux configuration registers.
Group1 pins out 128 lines(8 banks). Group 2 pins out 36 lines(2 banks).
Add DT nodes for each module instance in the main domain. Users should
make sure that correct gpio instance is selected in their pad configuration.

Update the power-domain cells to 2 and mark all devices as
exclusive. Main uart 0 is the debug console for processor boards
and it is used by different software entities like u-boot, atf,
linux simultaneously. So just mark main_uart0 as shared device
for common processor board.

TISCI protocol supports for enabling the device either with exclusive
permissions for the requesting host or with sharing across the hosts.
There are certain devices which are exclusive to Linux context and
there are certain devices that are shared across different host contexts.
So add support for getting this information from DT by increasing
the power-domain cells to 2.
For keeping the DT backward compatibility intact, defaulting the
device permissions to set the exclusive flag set. In this case the
power-domain-cells is 1.

Sysfw provides an option for requesting exclusive access for a
device using the flags MSG_FLAG_DEVICE_EXCLUSIVE. If this flag is
not used, the device is meant to be shared across hosts. Once a device
is requested from a host with this flag set, any request to this
device from a different host will be nacked by sysfw. Current tisci
driver enables this flag for every device requests. But this may not
be true for all the devices. So provide a separate commands in driver
for exclusive and shared device requests.

Pull structleak fix from Kees Cook:
"Disable gcc-based stack variable auto-init under KASAN (Arnd
Bergmann).
This fixes a bunch of build warnings under KASAN and the
gcc-plugin-based stack auto-initialization features (which are
arguably redundant, so better to let KASAN control this)"

The combination of KASAN_STACK and GCC_PLUGIN_STRUCTLEAK_BYREF
leads to much larger kernel stack usage, as seen from the warnings
about functions that now exceed the 2048 byte limit:
drivers/media/i2c/tvp5150.c:253:1: error: the frame size of 3936 bytes is larger than 2048 bytes

The structleak plugin was previously disabled for CONFIG_COMPILE_TEST,
but meant we missed some bugs, so this time we should address them.
The frame size warnings are distracting, and risking a kernel stack
overflow is generally not beneficial to performance, so it may be best
to disallow that particular combination. This can be done by turning
off either one. I picked the dependency in GCC_PLUGIN_STRUCTLEAK_BYREF
and GCC_PLUGIN_STRUCTLEAK_BYREF_ALL, as this option is designed to
make uninitialized stack usage less harmful when enabled on its own,
but it also prevents KASAN from detecting those cases in which it was
in fact needed.
KASAN_STACK is currently implied by KASAN on gcc, but could be made a
user selectable option if we want to allow combining (non-stack) KASAN
with GCC_PLUGIN_STRUCTLEAK_BYREF.
Note that it would be possible to specifically address the files that
print the warning, but presumably the overall stack usage is still
significantly higher than in other configurations, so this would not
address the full problem.
I could not test this with CONFIG_INIT_STACK_ALL, which may or may not
suffer from a similar problem.

In test_firmware_init(), the buffer pointed to by the global pointer
'test_fw_config' is allocated through kzalloc(). Then, the buffer is
initialized in __test_firmware_config_init(). In the case that the
initialization fails, the following execution in test_firmware_init() needs
to be terminated with an error code returned to indicate this failure.
However, the allocated buffer is not freed on this execution path, leading
to a memory leak bug.
To fix the above issue, free the allocated buffer before returning from
test_firmware_init().

Currently, a transaction to context manager from its own process
is prevented by checking if its binder_proc struct is the same as
that of the sender. However, this would not catch cases where the
process opens the binder device again and uses the new fd to send
a transaction to the context manager.

VRHOT event from the F/W indicates the device has reached a temperature of
100 Celsius degrees. In this case, the driver should only print this
information to the kernel log. The device will shutdown itself
automatically when reaching 125 degrees.

dma_addr_t might be different sizes depending on the configuration,
so we cannot print it as %llx:
drivers/misc/habanalabs/goya/goya.c: In function 'goya_sw_init':
drivers/misc/habanalabs/goya/goya.c:698:21: error: format '%llx' expects argument of type 'long long unsigned int', but argument 4 has type 'dma_addr_t' {aka 'unsigned int'} [-Werror=format=]
Use the special %pad format string. This requires passing the
argument by reference.

The "WITH Linux-syscall-note" exception exists for headers exported to
user space. It is strange to add it to non-exported headers.
Commit 687a3e4d8e61 ("treewide: remove SPDX "WITH Linux-syscall-note"
from kernel-space headers") did cleanups some months ago, but it looks
like we need to do this periodically.
This patch was generated by the following script:
git grep -l -e Linux-syscall-note \
-- :*.h :^arch/*/include/uapi/asm/*.h :^include/uapi/ :^tools |
while read file
do
sed -i -e 's/(\(GPL-[^[:space:]]*\) WITH Linux-syscall-note)/\1/g' \
-e 's/ WITH Linux-syscall-note//g' $file
done
I did not commit drivers/staging/android/uapi/ion.h . This header is
not currently exported, but somebody may plan to move it to include/uapi/
when the time comes. I am not sure. Anyway, it will be better to check
the license inconsistency in drivers/staging/android/uapi/.

UAPI headers licensed under GPL are supposed to have exception
"WITH Linux-syscall-note" so that they can be included into non-GPL
user space application code.
The exception note is missing in some UAPI headers.
Some of them slipped in by the treewide conversion commit b24413180f56
("License cleanup: add SPDX GPL-2.0 license identifier to files with
no license"). Just run:
$ git show --oneline b24413180f56 -- arch/x86/include/uapi/asm/
I believe they are not intentional, and should be fixed too.
This patch was generated by the following script:
git grep -l --not -e Linux-syscall-note --and -e SPDX-License-Identifier \
-- :arch/*/include/uapi/asm/*.h :include/uapi/ :^*/Kbuild |
while read file
do
sed -i -e '/[[:space:]]OR[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
-e '/[[:space:]]or[[:space:]]/s/\(GPL-[^[:space:]]*\)/(\1 WITH Linux-syscall-note)/g' \
-e '/[[:space:]]OR[[:space:]]/!{/[[:space:]]or[[:space:]]/!s/\(GPL-[^[:space:]]*\)/\1 WITH Linux-syscall-note/g}' $file
done
After this patch is applied, there are 5 UAPI headers that do not contain
"WITH Linux-syscall-note". They are kept untouched since this exception
applies only to GPL variants.

A second regression was found in the immediate data transfer (IDT)
support which was added to 5.2 kernel
IDT is used to transfer small amounts of data (up to 8 bytes) in the
field normally used for data dma address, thus avoiding dma mapping.
If the data was not already dma mapped, then IDT support assumed data was
in urb->transfer_buffer, and did not take into accound that even
small amounts of data (8 bytes) can be in a scatterlist instead.
This caused a NULL pointer dereference when sg_dma_len() was used
with non-dma mapped data.
Solve this by not using IDT if scatter gather buffer list is used.

This is a partial revert of 73d31def1aab "usb: usb251xb: Create a ports
field collector method", which broke a existing devicetree
(arch/arm64/boot/dts/freescale/imx8mq.dtsi).
There is no reason why the swap-dx-lanes property should not apply to
the upstream port. The reason given in the breaking commit was that it's
inconsitent with respect to other port properties, but in fact it is not.
All other properties which only apply to the downstream ports explicitly
reject port 0, so there is pretty strong precedence that the driver
referred to the upstream port as port 0. So there is no inconsistency in
this property at all, other than the swapping being also applicable to
the upstream port.

This property isn't needed and not yet used anywhere. The swap-dx-lanes

lanes.

This patch fixes an issue that the following error happens on
swiotlb environment:
xhci-hcd ee000000.usb: swiotlb buffer is full (sz: 524288 bytes), total 32768 (slots), used 1338 (slots)
On the kernel v5.1, block settings of a usb-storage with SuperSpeed
were the following so that the block layer will allocate buffers
up to 64 KiB, and then the issue didn't happen.
max_segment_size = 65536
max_hw_sectors_kb = 1024
After the commit 09324d32d2a0 ("block: force an unlimited segment
size on queues with a virt boundary") is applied, the block settings
are the following. So, the block layer will allocate buffers up to
1024 KiB, and then the issue happens:
max_segment_size = 4294967295
max_hw_sectors_kb = 1024
To fix the issue, the usb-storage driver checks the maximum size of
a mapping for the device and then adjusts the max_hw_sectors_kb
if required. After this patch is applied, the block settings will
be the following, and then the issue doesn't happen.
max_segment_size = 4294967295
max_hw_sectors_kb = 256

usb_amd_find_chipset_info() is used for chipset detection for
several quirks. It is strange that its return value indicates
the need for the PLL quirk, which means it is often ignored.
This patch adds a function specifically for checking the PLL
quirk like the other ones. Additionally, rename probe_result to
something more appropriate.

The AMD PLL USB quirk is incorrectly enabled on newer Ryzen
chipsets. The logic in usb_amd_find_chipset_info currently checks
for unaffected chipsets rather than affected ones. This broke
once a new chipset was added in e788787ef. It makes more sense
to reverse the logic so it won't need to be updated as new
chipsets are added. Note that the core of the workaround in
usb_amd_quirk_pll does correctly check the chipset.

Pull ARM SoC fixes from Olof Johansson:
"Here's the first batch of fixes for this release cycle.
Main diffstat here is the re-deletion of netx. I messed up and most
likely didn't remove the files from the index when I test-merged this
and saw conflicts, and from there on out 'git rerere' remembered the
mistake and I missed checking it. Here it's done again as expected.
Besides that:
- A defconfig refresh + enabling of new drivers for u8500
- i.MX fixlets for i2c/SAI/pinmux
- sleep.S build fix for Davinci
- Broadcom devicetree build/warning fix"

i.MX fixes for 5.3:
- Fix i.MX8MM SAI3 RXC/TXFS pinmux configuration.
- Fix i.MX7ULP usb-phy unit address to drop extra '0x' notation.
- Fix typo of clock frequency property name in a few i.MX6UL board
I2C buses.
- Drop "fsl,imx6sx-sai" from i.MX8M SAI device, as it's not compatible
with i.MX6SX SAI.

The i.MX8M SAI block is not compatible with the i.MX6SX one, as the
register layout has changed due to two version registers being added
at the beginning of the address map. Remove the bogus compatible.

According to i.MX8MM reference manual Rev.1, 03/2019:
SAI3_RXC pin's mux option #1 should be GPT1_CLK, NOT GPT1_CAPTURE2;
SAI3_TXFS pin's mux option #1 should be GPT1_CAPTURE2, NOT GPT1_CLK.

A few boards set clock frequency of their I2C buses with
"clock_frequency" property. The right property is "clock-frequency".
