Commit Message

Manne, Nava kishore Oct. 13, 2022, 9:05 a.m. UTC
  Adds PM API for performing Programmable Logic(PL) configuration
register readback. It provides an interface to the firmware(pmufw)
to readback the FPGA configuration register.

Signed-off-by: Nava kishore Manne <nava.kishore.manne@amd.com>
---
hanges for v2:
              - None.

Changes for v3:
              - Updated API and config reg read-back handling logic
              - Updated the commit msg to align with the changes.
