Move gpio lock as irq from "domain alloc" callback to "domain activate"
callback. It will allow to use gpiolib sysfs correctly.

Based on the Allwinner H5 datasheet and the pinctrl driver of the
backward-compatible H3 this introduces the pin multiplex assignments for
the H5 SoC.
H5 introduced some more pin functions (e.g. three more groups of TS
pins, and one more groups of SIM pins) than H3.

This driver adds pinctrl/GPIO support for Intel Gemini Lake SoC. The
GPIO controller is based on the next generation GPIO hardware but still
compatible with the one supported by the Intel core pinctrl/GPIO driver.
This commit includes material from David E. Box.

The next generation Intel GPIO hardware has two additional registers
PADCFG2 and PADCFG3. The latter is marked as reserved but the former
includes configuration for per-pad hardware debouncer.
This patch adds support for that in the Intel pinctrl core driver. Since
these are additional features on top of the current generation hardware,
we use revision number and feature flags to enable this if detected.

I've seen this trigger twice now, where the i915_gem_object_to_ggtt()
call in intel_unpin_fb_obj() returns NULL, resulting in an oops
immediately afterwards as the (inlined) call to i915_vma_unpin_fence()
tries to dereference it.
It seems to be some race condition where the object is going away at
shutdown time, since both times happened when shutting down the X
server. The call chains were different:
- VT ioctl(KDSETMODE, KD_TEXT):
intel_cleanup_plane_fb+0x5b/0xa0 [i915]
drm_atomic_helper_cleanup_planes+0x6f/0x90 [drm_kms_helper]
intel_atomic_commit_tail+0x749/0xfe0 [i915]
intel_atomic_commit+0x3cb/0x4f0 [i915]

entry_SYSCALL_64_fastpath+0x13/0x94
- i915 unpin_work workqueue:
intel_unpin_work_fn+0x58/0x140 [i915]
process_one_work+0x1f1/0x480
worker_thread+0x48/0x4d0
kthread+0x101/0x140
and this patch purely papers over the issue by adding a NULL pointer
check and a WARN_ON_ONCE() to avoid the oops that would then generally
make the machine unresponsive.
Other callers of i915_gem_object_to_ggtt() seem to also check for the
returned pointer being NULL and warn about it, so this clearly has
happened before in other places.
[ Reported it originally to the i915 developers on Jan 8, applying the
ugly workaround on my own now after triggering the problem for the
second time with no feedback.
This is likely to be the same bug reported as
https://bugs.freedesktop.org/show_bug.cgi?id=98829https://bugs.freedesktop.org/show_bug.cgi?id=99134
which has a patch for the underlying problem, but it hasn't gotten to
me, so I'm applying the workaround. ]

Pull i2c fixes from Wolfram Sang:
"Two I2C driver bugfixes.

i2c: imx-lpi2c: add VLLS mode support
i2c: i2c-cadence: Initialize configuration before probing devices
In swab.h the "#if BITS_PER_LONG > 32" breaks compiling userspace programs if
BITS_PER_LONG is #defined by userspace with the sizeof() compiler builtin.
Solve this problem by using __BITS_PER_LONG instead. Since we now
#include asm/bitsperlong.h avoid further potential userspace pollution
by moving the #define of SHIFT_PER_LONG to bitops.h which is not
exported to userspace.
This patch unbreaks compiling qemu on hppa/parisc.
