Ikjoon Jang April 15, 2021, 3:29 a.m. UTC
Add device a tree binding for a "cros-cbas" switch device of
ChromeOS tablets with Whiskers base board.

Changes in v5:
 - Add missing blank lines and change the description property's position.
 - Add a note to description: "this device cannot be detected at runtime."

Changes in v4:
Define cros-cbase bindings inside google,cros-ec.yaml instead of
a separated binding document.

Ikjoon Jang (2):
  mfd: google,cros-ec: add DT bindings for a baseboard's switch device
  HID: google: Add of_match table to Whiskers switch device.

Sorry, I'm a bit confused here.
'base_detection: cbas' in example should be just 'cbas'?
Maybe that's because cbas doesn't need to have a phandle or just by
its definition in schema?

Please let me upload v6 if this needs to be fixed.

Thanks for reviewing!
