Hi Geert,

Thank you for the patch.

Shouldn't we also define the always-on power domain for the other SoCs 
(patches 2/7 to 6/7 in this series) ? I know they're already covered by the 
cpg power domain, but going forward I believe that standardizing on the SYSC 
power domains would be beneficial. We of course have to keep backward 
compatibility in the implementation.

This isn't an issue for this patch, so
