Hi Shreeya,

As we are making this Zhigang Shi's problem to maintain, I'm 
looking for an ack.  Bit mean otherwise :)

Except for the deprecated part this could just have gone in
trivial-bindings.yaml.

I guess you don't need it for your existing board, but best
practice would probably include ensuring whatever supplies
the device needs are here so that platforms that don't enable
them by default can turn them on.

Also, there is an interrupt according to the datasheet linked
from patch 3 and that should definitely be in the binding
even if the driver isn't using it.
