Filename based on compatible.
This is not specific for SDX75. These are generic ones that should be
used for all other targets.
Konrad suggested in v1 to avoid target specific prefixes everytime and
to create a new generic
dt-bindings that can be reused.

These are very generic names, usually not used in global headers. Please
use some reasonable prefix.
This was based on the suggestion from Konrad in v2 to drop the RPMHPD
prefix and we can go only with names like CX, etc.

I don't think having so generic name in tree-wide header is good idea.
Conversely, I think that it would be very clear in files including this header.

It is expected to be included into dtsi and into rpmhpd driver (only). However I'd also suggest adding some generic prefix (e.g. RPMHPD_CX). Just `CX' is too short and has a sensible possibility of getting a symbol conflict.


Konrad
CX can mean anything.

Krzysztof
