What's the meaning of "PSP_CMDRESP_RESP"? I see that this new macro
name is currently used by other drivers, but in my opinion "READY" is
more descriptive. (It is also aligned to the comment above this line.)
It should indicate that the PSP has responded. I think both terms work
to describe what's going on.
Tom - What's your preference?
I'll either adjust all the drivers to use READY or fix the comment for v2.
I think the comment should be changed.
Thanks,
Tom
