[PATCH v3 0/3] watchdog: rzv2h: Convert WDTDCR handling to regmap

From: Lad Prabhakar <[email protected]>

Hi All,

This patch series converts the WDTDCR register access from raw
readl/writel variants over to the regmap framework using
devm_regmap_init_mmio(). This conversion serves as a preparatory
refactoring step. It allows the driver to subsequently support
syscon-based system controllers natively by passing along alternative
regmap handles without forcing messy architectural branching at runtime.

Note,
 - This change was suggested [0]
   [0] https://lore.kernel.org/all/[email protected]/ 
- Patches are rebased on top of next-20260813

v2->v3:
- Patch#1, is split from v2 patch #1 to make thing easier to review.
- Moved unwinding changes to patch#1.
- Set use_raw_spinlock to true in regmap config as certain watchdog operations
  runs in an atomic panic context.
- Updated commit message to reflect the change for patch#3.

v1->v2:
 - Dropped patch #1 from v1 series.
 - Switched to use regmap_set/clear_bits()

v2: https://lore.kernel.org/all/[email protected]/
v1: https://lore.kernel.org/all/[email protected]/

Cheers,
Prabhakar
