Hi folks,

This series adds initial SoC support for the GS101 SoC and also initial board
support for Pixel 6 phone (Oriole).

Thankyou to everyone who has reviewed and tested the previous series. Your
time and effort doing so is much appreciated! If any relevant subsystem
maintainers can send a acked-by that would be much appreciated. In particular

@RobH: Please can you re-review google.yaml as a ect node was added since you
gave your previous reviewed-by

@Guenter/Wim: If you're happy, can you send an acked-by for Watchdog changes?

V7 incorporates the review feedback received so far, and is rebased onto
linux-next as per Krzysztof request to incorporate all his dt-binding changes
for exynos. I'm really hoping V7 will be the last series, and we can get this
series merged this week so it will make it into v6.8 Linux release.

v7 fixes up various cosmetic nits in device tree and drivers regarding
alphabetical ordering. See below for more verbose details. There is one
additional patch to fixup some incorrect numbering and spelling typo
in the google,gs101.h. Also the patches which have already been applied
have been dropped from the series.

As this series spans multiple subsytems the expectation is that Krzysztof
will apply the whole series through the Samsung SoC tree. If the relevant
subsystem maintainers can give a acked-by or reviewed-by on the relevant
patches that would be most appreciated!

The gs101 / Tensor SoC is also used in Pixel6a (bluejay) and Pixel 6 Pro
(raven) phones. Currently DT is added for the gs101 SoC and Oriole.
As you can see from the patches the SoC is based on a Samsung Exynos SoC,
and therefore lots of the low level Exynos drivers and bindings can be
re-used.

The support added in this series consists of:
* cpus
* pinctrl
* CCF implementation of cmu_top, cmu_misc & cmu_apm
* watchdog
* USI uart
* gpio

This is enough to boot through to a busybox initramfs and shell using an
upstream kernel though :) More platform support will be added over the
following weeks and months.

For further information on how to build and flash the upstream kernel on your
Pixel 6, with a prebuilt busybox initramfs please refer to the script and
README.md here:

https://git.codelinaro.org/linaro/googlelt/pixelscripts

Note: Booting without a dtbo works with some versions of the bootloader
but crashes on others. Later versions aren't necessarily better. You can
get the bootloader version with `fastboot getvar version-bootloader`
Known good bootloader versions are: -
- slider-1.3-11000330
- slider-1.2-9152140
Known to crash without dtbo
- slider-1.3-10780582

kind regards,

Peter.

Ah! I see you have change use BIT here, so you can squash this patch to
patch 10/16 or
Move BIT change from patch 10/16 to this patch. Either way is fine.

I actually kept them separate deliberately to avoid conflating adding
of the DBGACK quirk with cleanup of the driver to use BIT macro.

As such one patch adds the QUIRK and only updates the macros that were
touched by that patch (to avoid the --strict warnings), and the second
patch cleans up the rest of the macros to use BIT macro for
consistency.

Peter
