Please instead introduce a set of defines without the SoC prefix
(i.e. CX, CX_AO, MX etc.). We've been putting this off for too long
and you're the first unlucky guy that submitted new RPMhPD support after
we've concluded it'd be the way to go! :D Sadly, we can't replace the
existing ones retroactively..

Surely No issues. Will update it.

I have a doubt here. Cant we completely omit the #defines here and 
directly index this as 0,1,...
because if the intention of this #defines is to understand the name of 
the pd then we can get
it from the .name attribute in rpmhpd as well, right?

The problems with a common set of #define would be, lets say if we 
define CX_AO as 1 and some platform
doesn't have CX_AO then wouldnt it leave a null entry in the driver 
entry of that platform?

Thanks,
Rohit.

Yes.

We already do this in the rpmh clock driver, as:

1. there are domains that all chips share (like CX etc.)
2. wasting a couple of bytes lets us massively save on convolution
