When cold-booting Asus X434DA, GPIO 7 is found to be already configured
as an interrupt, and the GPIO level is found to be in a state that
causes the interrupt to fire.
As soon as pinctrl-amd probes, this interrupt fires and invokes
amd_gpio_irq_handler(). The IRQ is acked, but no GPIO-IRQ handler was
invoked, so the GPIO level being unchanged just causes another interrupt
to fire again immediately after.
This results in an interrupt storm causing this platform to hang
during boot, right after pinctrl-amd is probed.
Detect this situation and disable the GPIO interrupt when this happens.
This enables the affected platform to boot as normal. GPIO 7 actually is
the I2C touchpad interrupt line, and later on, i2c-multitouch loads and
re-enables this interrupt when it is ready to handle it.
Instead of this approach, I considered disabling all GPIO interrupts at
probe time, however that seems a little risky, and I also confirmed that
Windows does not seem to have this behaviour: the same 41 GPIO IRQs are
enabled under both Linux and Windows, which is a far larger collection
than the GPIOs referenced by the DSDT on this platform.

On Asus X571GT, GPIO 297 is configured as an interrupt and serves
for the touchpad. The touchpad will report input events much less
than expected after S3 suspend/resume, which results in extremely
slow cursor movement. However, the number of interrupts observed
from /proc/interrupts increases much more than expected even no
touching touchpad.
This is due to the value of PADCFG0 of PIN 225 for the interrupt
has been changed from 0x80800102 to 0x80100102. The GPIROUTIOXAPIC
is toggled on which results in the spurious interrupts. The PADCFG0
of PIN 225 is expected to be saved during suspend, but the 297 is
saved instead because the gpiochip_line_is_irq() expect the GPIO
offset but what's really passed to it is PIN number. In this case,
the /sys/kernel/debug/pinctrl/INT3450:00/gpio-ranges shows
288: INT3450:00 GPIOS [436 - 459] PINS [216 - 239]
So gpiochip_line_is_irq() returns true for GPIO offset 297, the
suspend routine spuriously saves the content for PIN 297 which
we expect to save for PIN 225.
This commit maps the PIN number to GPIO offset first in the
intel_pinctrl_should_save() to make sure the values for the
specific PINs can be correctly saved and then restored.

that codebase, and two are some small iio fixes.
All of these have been in linux-next this week with no reported issues.

Here are number of small USB fixes for 5.3-rc5.
Syzbot has been on a tear recently now that it has some good USB
debugging hooks integrated, so there's a number of fixes in here found
by those tools for some _very_ old bugs. Also a handful of gadget
driver fixes for reported issues, some hopefully-final dma fixes for
host controller drivers, and some new USB serial gadget driver ids.
All of these have been in linux-next this week with no reported issues
(the usb-serial ones were in linux-next in its own branch, but merged
into mine on Friday.)

Pull arm64 fixes from Catalin Marinas:
- Don't taint the kernel if CPUs have different sets of page sizes
supported (other than the one in use).
- Issue I-cache maintenance for module ftrace trampoline.
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: ftrace: Ensure module ftrace trampoline is coherent with I-side
arm64: cpufeature: Don't treat granule sizes as strict
The initial support for dynamic ftrace trampolines in modules made use
of an indirect branch which loaded its target from the beginning of
a special section (e71a4e1beb ("arm64: ftrace: add support for far
branches to dynamic ftrace")). Since no instructions were being patched,
no cache maintenance was needed. However, later in be0f272bfc ("arm64:
ftrace: emit ftrace-mod.o contents through code") this code was reworked
to output the trampoline instructions directly into the PLT entry but,
unfortunately, the necessary cache maintenance was overlooked.
Add a call to __flush_icache_range() after writing the new trampoline
instructions but before patching in the branch to the trampoline.
