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

+description: |
+  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
+
+properties:
+  $nodename:
+    const: '/'
+  compatible:
