[PATCH v7 02/16] dt-bindings: arm: google: Add bindings for Google ARM platforms

[Peter Griffin <peter.griffin@linaro.org>]

This introduces bindings and dt-schema for the Google Tensor SoCs.
Currently just gs101 and pixel 6 are supported.

@RobH I removed your 'Reviewed-by: Rob Herring <robh@kernel.org>' tag
as since you reviewed this I added the empty ect node. Can you please
do the review again?

+  ARM platforms using SoCs designed by Google branded "Tensor" used in Pixel
+  devices.
+
+  Currently upstream this is devices using "gs101" SoC which is found in Pixel
+  6, Pixel 6 Pro and Pixel 6a.
+
+  Google have a few different names for the SoC:
+  - Marketing name ("Tensor")
+  - Codename ("Whitechapel")
+  - SoC ID ("gs101")
+  - Die ID ("S5P9845")
+
+  Likewise there are a couple of names for the actual device
+  - Marketing name ("Pixel 6")
+  - Codename ("Oriole")
+
+  Devicetrees should use the lowercased SoC ID and lowercased board codename,
+  e.g. gs101 and gs101-oriole.
