This tag contains the following fixes for 5.11-rc2:

- Fixes that are needed for supporting the new F/W with security features:
  - Correctly fetch PLL information in GOYA when security is enabled in F/W
  - Fix hard-reset support when F/W is in its preboot stage
  - Disable clock gating when initializing the H/W
  - Fix hard-reset procedure
