Subject: [PATCH v3 0/3] regcache: Avoid accessing non-initialised cache
Date: Thu, 26 Feb 2026 14:57:08 +0100	[thread overview]
Message-ID: <20260226135918.381979-1-andriy.shevchenko@linux.intel.com> (raw)

Refactor regcache flow that populates cache on initialisation phase
based on the values in HW. This makes code robust against any possible
accesses to not-fully initialised caches.

Changelog v3:
- dropped unneeded churn in patch 3 (Mark)
- fixed code to pass kunit test cases (Mark)

v2: 20260225161659.3811671-1-andriy.shevchenko@linux.intel.com

Changelog v2:
- rebased on top of the latest regmap changes (Mark)
- added two more little cleanups (patches 4 & 5)

Andy Shevchenko (3):
  regcache: Move HW readback after cache initialisation
  regcache: Define iterator inside for-loop and align their types
  regcache: Amend printf() specifiers when printing registers
