The commit 458de58424 ("arm64: dts: qcom: x1e80100: move dp0/1/2
data-lanes to SoC dtsi") has landed before this file was added, so
the data-lanes lines here remained.

On the HAMOA-IOT-EVK board only 2 out of 4 speakers were functional.
Unlike the CRD, which shares a single GPIO reset line for WSA1/2,
this board provides a dedicated GPIO reset for each WSA, resulting
in 4 separate reset lines.
Update the device tree accordingly so that all 4 speakers can

The laptop comes in two variants:
* UX3407RA, higher end, FHD+ OLED or WOXGA+ OLED panels
* UX3407QA, lower end, FHD+ OLED or FHD+ LCD panels
Even though all three panels work with "edp-panel", unfortunately the
brightness adjustmenet of LCD panel is PWM based, requiring a dedicated
device-tree. Convert "x1p42100-asus-zenbook-a14.dts" into ".dtsi" to
allow for this split, introduce new LCD variant. Leave current variant
without postfix and with the unchanged model name, as some distros
(eg. Ubuntu) rely on this for automatic device-tree detection during
kernel installation/upgrade.
As dedicated device-tree is required, update compatibles of OLED
variants to correct ones. Keep "edp-panel" as fallback, since it is
enough to make the panels work.
While at it moving .dts, .dtsi around, drop 'model' from the top level
x1-asus-zenbook-a14.dtsi as well.

Let the PMU driver request both NMIs and normal interrupts with an affinity mask
matching the PMU affinity.

While it would be nice to simply make request_percpu_irq() take an affinity
mask, the churn is likely to be on the irritating side given that most
drivers do not give a damn about affinities.
So take the more innocuous path to provide a helper that parallels
request_percpu_irq(), with an affinity as a bonus argument.
Yes, request_percpu_irq_affinity() is a bit of a mouthful.

Interrupt sharing for percpu-devid interrupts is forbidden, and for good
reasons. These are interrupts generated *from* a CPU and handled by itself
(timer, for example). Nobody in their right mind would put two devices on
the same pin (and if they have, they get to keep the pieces...).
But this also prevents more benign cases, where devices are connected
to groups of CPUs, and for which the affinities are not overlapping.
Effectively, the only thing they share is the interrupt number, and
nothing else.
Tweak the definition of IRQF_SHARED applied to percpu_devid interrupts to
allow this particular use case. This results in extra validation at the
point of the interrupt being setup and freed, as well as a tiny bit of
extra complexity for interrupts at handling time (to pick the correct
irqaction).

Continue spreading the notion of affinity to the per CPU interrupt request
code by updating the call sites that use request_percpu_nmi() (all two of
them) to take an affinity pointer. This pointer is firmly NULL for now.

Add an affinity field to both the irqaction structure and the interrupt
request primitives. Nothing is making use of it yet, and the only value
used it NULL, which is used as a shorthand for cpu_possible_mask.
This will shortly get used with actual affinities.

Move the code creating a per-cpu irqaction into its own helper, so that
future changes to this code can be kept localised.
At the same time, fix the documentation which appears to say the wrong
thing when it comes to interrupts being automatically enabled
(percpu_devid interrupts never are).

When irqaction::percpu_dev_id was introduced, it was hoped that it could be
part of an anonymous union with dev_id, as the two fields are mutually
exclusive.
However, toolchains used at the time were often showing terrible support
for anonymous unions, breaking the build on a number of architectures. It
was therefore decided to keep the two fields separate and address this down
the line.
14 years later, the compiler dark age is over, and there is universal
support for anonymous unions. Get a whole pointer back that can immediately
be spent on something else.
