[v2] platform/x86: ISST: Fix for write lock and suspend/resume

[PATCH v2 0/2] platform/x86: ISST: Fix for write lock and suspend/resume

Posted by Srinivas Pandruvada 1 month ago

There are two issues, which are not urgent as the current deployed systems
don't support them, but need fixes:
- Write lock- Even if the TPMI is write locked it will still write to MMIO
- store-restore data during suspend/resume: Not storing and restoring data to
all power domains.

v2:
  One minor fix for new line

Srinivas Pandruvada (2):
  platform/x86: ISST: Add missing write block check
  platform/x86: ISST: Store and restore all domains data

Thank you for your contribution, it has been applied to my local
review-ilpo-next branch. Note it will show up in the public
platform-drivers-x86/review-ilpo-next branch only once I've pushed my
local branch there, which might take a while.
