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.

This is for ChromeOS tablets which have a 'cros_cbas' switch device
in the "Whiskers" base board. This device can be instantiated only by
device tree on ARM platforms. ChromeOS EC doesn't provide a way to
probe the device.

Thanks a lot!
Sorry for bothering you again but I can't find
a device tree binding patch [1] in your trees.
I think dt-binding should go first before the driver part.
Can it also be applied to hid tree (or am I missing something)?

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!

This is for ChromeOS tablets which have a 'cros_cbas' switch device
in the "Whiskers" base board. This device can be instantiated only by
device tree on ARM platforms. ChromeOS EC doesn't provide a way to
probe the device.

Changes in v6:
- Remove a label from cbas node in an example
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.
