Commit Message

Melody Olvera March 6, 2023, 11:11 p.m. UTC 
  This documents the compatible for the component used to boot the
MPSS on the QDU1000 and QRU1000 SoCs.

The QDU1000 and QRU1000 mpss boot process now requires the specification
of an RMB register space to complete the handshake needed to start or
attach the mpss.

You need to list the items instead (just like for clocks).

Wait, I already commented on this... Some other comments also ignored.

This is a friendly reminder during the review process.

It seems my previous comments were not fully addressed. Maybe my
feedback got lost between the quotes, maybe you just forgot to apply it.
Please go back to the previous discussion and either implement all
requested changes or keep discussing them.

Thank you.

Krzysztof

Last comments said to drop this since it's redundant from qcom,pas-common.yaml. Will drop per
our discussion on https://lore.kernel.org/all/aba45ae9-8558-50c1-e5ad-dd910dacdbb3@linaro.org/.
