[PATCH 00/21] Add minimal Tensor/GS101 SoC support and Oriole/Pixel6 board

[Peter Griffin <peter.griffin@xxxxxxxxxx>]

Hi folks,

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

The gs101 / Tensor SoC is also used in Pixel6a (bluejay) and Pixel 6 Pro (raven).
Currently DT is just added for the gs101 SoC and Oriole.

The support added in this series consists of:
* cpus
* pinctrl
* some CCF clock implementation
* watchdog
* 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. Currently we boot with clk_ignore_unused parameter but this will be
updated as more clocks and platform support lands.

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

I've also included the dtbo overlay containing board_id and board_rev in this
series as otherwise the LK bootloader will bootloop if this is not present in
the dtbo partition. It seems like it would be nicer for the upstream kernel to
build all the DT required to boot upstream kernel on a production phone rather
than having to obtain this dtbo from some other place, but if it is a pain point
then I can remove it.

Many thanks,

Peter.
