[PATCH v2 0/2] watchdog: rzv2h: Convert WDTDCR handling to regmap

Posted by Prabhakar 1 week, 3 days ago

From: Lad Prabhakar <prabhakar.mahadev-lad.rj@bp.renesas.com>

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.

- Patches are rebased on top of next-20260714

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

v1: https://lore.kernel.org/all/20260702160457.1884345-1-prabhakar.mahadev-lad.rj@bp.renesas.com/

Cheers,
