993254292b drm/i915: Refactor timestamping constants update
Once we do the hw vs. uapi split we can no longer use
drm_atomic_helper_calc_timestamping_constants() as it'll
consult the uapi state instead of the hw state.

So let's just update the vblank timestamping constants whenever
we update the scanline offset. We use both to convert the hw
scanline count to something which matches the software timing
values.

First I thought to put these into intel_crtc_vblank_on() but
we may want to get the scanline counter value before that (eg.
from some early tracepoints), so let's stick to updating them
a bit earlier than intel_crtc_vblank_on().

c136d4c71f pinctrl: aspeed-g6: Make SIG_DESC_CLEAR() behave intuitively
Signal descriptors can represent multi-bit bitfields and so have
explicit "enable" and "disable" states. However many descriptor
instances only describe a single bit, and so the SIG_DESC_SET() macro is
provides an abstraction for the single-bit cases: Its expansion
configures the "enable" state to set the bit and "disable" to clear.

SIG_DESC_CLEAR() was introduced to provide a similar single-bit
abstraction for for descriptors to clear the bit of interest. However
its behaviour was defined as the literal inverse of SIG_DESC_SET() - the
impact is the bit of interest is set in the disable path. This behaviour
isn't intuitive and doesn't align with how we want to use the macro in
practice, so make it clear the bit for both the enable and disable
paths.

b95e0bd23e pinctrl: nomadik: Drop support for latent IRQ
The latent IRQs are IRQs that have occurred when the system
was down in deep sleep and the GPIO block was powered off.
The PRCMU (power reset and control unit) knows which GPIO
line offset fired an IRQ to wake the system up (if so
desired) and this second IRQ was used to replay the action
when the system came back online after suspend().

This is now known to be the wrong approach to solve this
problem: in a patch series Lina Iyer has suggested to
instead make it possible to model the IRQs as hierarchical
with double parents.

Also the current device trees do not contain the right
information to make this code work, the latent IRQ is not
specified nowadays giving noise like this in the console:

[    0.612168] gpio 8012e000.gpio: IRQ index 1 not found
[    0.622523] gpio 8012e080.gpio: IRQ index 1 not found

Let's delete the latent IRQ code and reimplement it properly
when we need it.

2851ef521d pinctrl: armada-37xx: Pass irqchip when adding gpiochip
We need to convert all old gpio irqchips to pass the irqchip
setup along when adding the gpio_chip. For more info see
drivers/gpio/TODO.

For chained irqchips this is a pretty straight-forward
conversion.

ASoC: rt1011: Read and apply r0 and temperature device property
Typically, the r0 (calibration data) and temperature were measured in the factory.
This information is written into the non-volatile area
where keeps data whether factory reset or OS update.
In Chromium OS case, the coreboot will read the info from VPD and create
the device property for each rt1011.

6ec939f8b8 arm64/mm: Poison initmem while freeing with free_reserved_area()
Platform implementation for free_initmem() should poison the memory while
freeing it up. Hence pass across POISON_FREE_INITMEM while calling into
free_reserved_area(). The same is being followed in the generic fallback
for free_initmem() and some other platforms overriding it.

usercopy: Avoid soft lockups in test_check_nonzero_user()
On a machine with a 64K PAGE_SIZE, the nested for loops in

Even with a 4K PAGE_SIZE the test takes multiple seconds. Instead
tweak it to only scan a 1024 byte region, but make it cross the
page boundary.

899ee4afe5 arm64: use generic free_initrd_mem()
arm64 calls memblock_free() for the initrd area in its implementation of
free_initrd_mem(), but this call has no actual effect that late in the boot
process. By the time initrd is freed, all the reserved memory is managed by
the page allocator and the memblock.reserved is unused, so the only purpose
of the memblock_free() call is to keep track of initrd memory for debugging
and accounting.

Without the memblock_free() call the only difference between arm64 and the
generic versions of free_initrd_mem() is the memory poisoning.

Move memblock_free() call to the generic code, enable it there
for the architectures that define ARCH_KEEP_MEMBLOCK and use the generic
implementation of free_initrd_mem() on arm64.

9f94fadd75 soc/tegra: fuse: Register cell lookups for compatibility
Typically nvmem cells would be stored in device tree. However, for
compatibility with device trees that don't contain nvmem cell
definitions, register lookups for cells currently used by consumers.
This allows the consumers to use the same API to query cells from the
device tree or using the legacy mechanism.

96ee12b2a2 soc/tegra: fuse: Implement nvmem device
The nvmem framework provides a generic infrastructure and API to access
the type of information stored in fuses such as the Tegra FUSE block.

Implement an nvmem device that can be used to access the information in
a more generic way to decouple consumers from the custom Tegra API and
to add a more formal way of creating the dependency between the FUSE
device and the consumers.
