Add dedicated device-tree for 1080p version of Nyan Big in order to
describe display panel properly. FHD panel doesn't support modes other
than 1080p, hence it's wrong to use incompatible lower resolution panel
in device-tree.

Add device-tree for ASUS Transformer Pad TF300TG, which is a NVIDIA
Tegra30-based 2-in-1 detachable, originally running Android. It's a

All Tegra30 ASUS tablets have a similar design pattern in terms of
hardware integration of LVDS display panels, like exactly the same GPIOs
are used for power and reset, etc. Add a common device-tree for LVDS
display panels of Tegra30 ASUS tablets to avoid replicating the
boilerplate panel description.

Add common DTSI for Tegra30 ASUS Transformers. It will be used by multiple
device-trees of ASUS devices. The common part initially was born out of
the ASUS TF300T tablet's device-tree that was created by Michał Mirosław.
It was heavily reworked and improved by Svyatoslav Ryhel, Maxim Schwalm,
Ion Agorria et al.

The Medcom Wide and PAZ00 boards don't specify the power supply for the
backlight, which means that the Linux driver will provide a dummy one.
Wire up an explicit dummy to also make the DT schema validation succeed.
Unfortunately I don't have access to the schematics for the Medcom Wide,
so I don't know if a more accurate description is possible.
The AC100 (PAZ00) schematics from here:
https://www.s-manuals.com/pdf/motherboard/compal/compal_la-6352p_r1.0a_schematics.pdf
aren't entirely clear which one of the supplies powers backlight, but
the panel supply is probably close enough.

The "pwm-" prefix currently matches the DT schema for PWM controllers
and throws an error in that case. This is something that should be fixed
in the PWM DT schema, but in this case we can also preempt any such
conflict by naming the nodes after the pins like we do for many others
of these nodes.

Make the order of the clocks and clock-names properties match the order
in the device tree bindings. This isn't strictly necessary from a point
of view of the operating system because matching will be done based on
the clock-names, but it makes it easier to validate the device trees
against the DT schema.

In order to be able to pass DT schema validation, change the GPU nodes'
unit-address to the standard notation. Previously this was using a "0,"
prefix that originated from a time when the top-level device tree node
contained #address-cells = <2>.
Note that this technically breaks backwards-compatibility with certain
older versions of the U-Boot bootloader because early versions used a
hard-coded DT path lookup to find the GPU node and perform some fixups
on it. However, this was changed to a compatible string based lookup in
April 2016, so it's reasonable to expect people to update U-Boot on the
systems that they want to use this updated kernel DTB with.

that should always be preferred.

Regulators defined at the top level in device tree are no longer part of
a simple bus and therefore don't have a reg property. Nodes without a
reg property shouldn't have a unit-address either, so drop the unit
address from the node names. To ensure nodes aren't duplicated (in which
case they would end up merged in the final DTB), append the name of the
regulator to the node name.

Add Kconfig support for -Wimplicit-fallthrough for both GCC and Clang.
The compiler option is under configuration CC_IMPLICIT_FALLTHROUGH,
which is enabled by default.
Special thanks to Nathan Chancellor who fixed the Clang bug[1][2]. This
bugfix only appears in Clang 14.0.0, so older versions still contain
the bug and -Wimplicit-fallthrough won't be enabled for them, for now.
This concludes a long journey and now we are finally getting rid
of the unintentional fallthrough bug-class in the kernel, entirely. :)

interrupt controller.
- PCI/MSI:
- Prevent a use after free when PCI/MSI interrupts are released by
destroying the sysfs entries before freeing the memory which is
accessed in the sysfs show() function.
- Implement a mask quirk for the Nvidia ION AHCI chip which does not
advertise masking capability despite implementing it. Even worse the
chip comes out of reset with all MSI entries masked, which due to the
missing masking capability never get unmasked.
- Move the check which prevents accessing the MSI[X] masking for XEN
back into the low level accessors. The recent consolidation missed
that these accessors can be invoked from places which do not have
that check which broke XEN. Move them back to he original place
instead of sprinkling tons of these checks all over the code.

Pull irq fixes from Thomas Gleixner:
"A set of fixes for the interrupt subsystem
Core code:
- A regression fix for the Open Firmware interrupt mapping code where
a interrupt controller property in a node caused a map property in
the same node to be ignored.
Interrupt chip drivers:
- Workaround a limitation in SiFive PLIC interrupt chip which
silently ignores an EOI when the interrupt line is masked.
- Provide the missing mask/unmask implementation for the CSKY MP
interrupt controller.
PCI/MSI:
- Prevent a use after free when PCI/MSI interrupts are released by
destroying the sysfs entries before freeing the memory which is
accessed in the sysfs show() function.
- Implement a mask quirk for the Nvidia ION AHCI chip which does not
advertise masking capability despite implementing it. Even worse
the chip comes out of reset with all MSI entries masked, which due
to the missing masking capability never get unmasked.
