Hi Jassi,

Please ignore it for now.  I will resend after validating it with
remoteproc.

What is the difference between this and the existing 'sa8775p' compatible? Are
they both representing the same SoC series?

Nord is a gen newer

Okay. This should've been present in the commit message to make it clear.

This should be explained somewhere, e.g. in board/soc bindings or SoC ID
bindings. None of these are posted, so most of the patches being posted
could receive that comment - what is the difference and why commit msg
explains nothing.

Best regards,

Indeed! I should have posted SoC ID change [1] first to introduce Nord
SoC.
