[PATCH AUTOSEL 5.15 02/26] ARM: dts: imx7d-sdb: config the max pressure for tsc2046

[Sasha Levin]

From: Haibo Chen <haibo.chen@nxp.com>

[ Upstream commit e7c4ebe2f9cd68588eb24ba4ed122e696e2d5272 ]

Use the general touchscreen method to config the max pressure for
touch tsc2046(data sheet suggest 8 bit pressure), otherwise, for
ABS_PRESSURE, when config the same max and min value, weston will
meet the following issue,

[17:19:39.183] event1  - ADS7846 Touchscreen: is tagged by udev as: Touchscreen
[17:19:39.183] event1  - ADS7846 Touchscreen: kernel bug: device has min == max on ABS_PRESSURE
[17:19:39.183] event1  - ADS7846 Touchscreen: was rejected
[17:19:39.183] event1  - not using input device '/dev/input/event1'

This will then cause the APP weston-touch-calibrator can't list touch devices.

root@imx6ul7d:~# weston-touch-calibrator
could not load cursor 'dnd-move'
could not load cursor 'dnd-copy'
could not load cursor 'dnd-none'
No devices listed.

And accroding to binding Doc, "ti,x-max", "ti,y-max", "ti,pressure-max"
belong to the deprecated properties, so remove them. Also for "ti,x-min",
"ti,y-min", "ti,x-plate-ohms", the value set in dts equal to the default
value in driver, so are redundant, also remove here.

[PATCH AUTOSEL 5.15 03/26] soc: mediatek: Let PMIC Wrapper and SCPSYS depend on OF

[Sasha Levin]

From: Jean Delvare <jdelvare@suse.de>

[ Upstream commit 2778caedb5667239823a29148dfc48b26a8b3c2a ]

With the following configuration options:
CONFIG_OF is not set
CONFIG_MTK_PMIC_WRAP=y
CONFIG_MTK_SCPSYS=y
we get the following build warnings:

  CC      drivers/soc/mediatek/mtk-pmic-wrap.o
drivers/soc/mediatek/mtk-pmic-wrap.c:2138:34: warning: ‘of_pwrap_match_tbl’ defined but not used [-Wunused-const-variable=]
drivers/soc/mediatek/mtk-pmic-wrap.c:1953:34: warning: ‘of_slave_match_tbl’ defined but not used [-Wunused-const-variable=]
  CC      drivers/soc/mediatek/mtk-scpsys.o
drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=]

Looking at the code, both drivers can only bind to OF-defined device
nodes, so these drivers are useless without OF and should therefore
depend on it.

Also drop of_match_ptr() from both drivers. We already know what it
will resolve to, so we might as well save cpp some work.

Developers or QA teams who wish to test-build the code can still do
so by enabling CONFIG_OF, which is available on all architectures and
has no dependencies.

[PATCH AUTOSEL 5.15 11/26] kselftest/arm64: Fix validatation termination record after EXTRA_CONTEXT

[Sasha Levin]

From: Mark Brown <broonie@kernel.org>

[ Upstream commit 5c152c2f66f9368394b89ac90dc7483476ef7b88 ]

When arm64 signal context data overflows the base struct sigcontext it gets
placed in an extra buffer pointed to by a record of type EXTRA_CONTEXT in
the base struct sigcontext which is required to be the last record in the
base struct sigframe. The current validation code attempts to check this
by using GET_RESV_NEXT_HEAD() to step forward from the current record to
the next but that is a macro which assumes it is being provided with a
struct _aarch64_ctx and uses the size there to skip forward to the next
record. Instead validate_extra_context() passes it a struct extra_context
which has a separate size field. This compiles but results in us trying
to validate a termination record in completely the wrong place, at best
failing validation and at worst just segfaulting. Fix this by passing
the struct _aarch64_ctx we meant to into the macro.

[PATCH AUTOSEL 5.15 13/26] arm64: run softirqs on the per-CPU IRQ stack

[Sasha Levin]

From: Qi Zheng <zhengqi.arch@bytedance.com>

[ Upstream commit 8eb858c44b98e0326bb32fca34ae671995cd73bb ]

Currently arm64 supports per-CPU IRQ stack, but softirqs
are still handled in the task context.

Since any call to local_bh_enable() at any level in the task's
call stack may trigger a softirq processing run, which could
potentially cause a task stack overflow if the combined stack
footprints exceed the stack's size, let's run these softirqs
on the IRQ stack as well.

[PATCH AUTOSEL 5.15 14/26] arm64: dts: imx8mq-librem5: Add bq25895 as max17055's power supply

[Sasha Levin]

From: Sebastian Krzyszkowiak <sebastian.krzyszkowiak@puri.sm>

[ Upstream commit 6effe295e1a87408033c29dbcea9d5a5c8b937d5 ]

This allows the userspace to notice that there's not enough
current provided to charge the battery, and also fixes issues
with 0% SOC values being considered invalid.

[PATCH AUTOSEL 5.15 15/26] ARM: orion: fix include path

[Sasha Levin]

From: Arnd Bergmann <arnd@arndb.de>

[ Upstream commit 63872304bdb3decd5454f4dd210c25395278ed13 ]

Now that CONFIG_ARCH_MULTIPLATFORM can be disabled anywhere,
there is a build failure for plat-orion:

arch/arm/plat-orion/irq.c:19:10: fatal error: plat/irq.h: No such file or directory

Make the include path unconditional.

[PATCH AUTOSEL 5.15 24/26] arm64: dts: uniphier: Add USB-device support for PXs3 reference board

[Sasha Levin]

From: Kunihiko Hayashi <hayashi.kunihiko@socionext.com>

[ Upstream commit 19fee1a1096d21ab1f1e712148b5417bda2939a2 ]

PXs3 reference board can change each USB port 0 and 1 to device mode
with jumpers. Prepare devicetree sources for USB port 0 and 1.

This specifies dr_mode, pinctrl, and some quirks and removes nodes for
unused phys and vbus-supply properties.

[PATCH AUTOSEL 5.15 25/26] ARM: 9242/1: kasan: Only map modules if CONFIG_KASAN_VMALLOC=n

[Sasha Levin]

From: Alex Sverdlin <alexander.sverdlin@nokia.com>

[ Upstream commit 823f606ab6b4759a1faf0388abcf4fb0776710d2 ]

In case CONFIG_KASAN_VMALLOC=y kasan_populate_vmalloc() allocates the
shadow pages dynamically. But even worse is that kasan_release_vmalloc()
releases them, which is not compatible with create_mapping() of
MODULES_VADDR..MODULES_END range:
