Subject: [PATCH v4 0/2] Add Watchdog Timer driver for Renesas RZ/V2H(P) SoC

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

Hi All,

This patch series aims to add WDT support to Renesas RZ/V2H(P)
SoC.

v3->v4
- Simplified calculation of max_hw_heartbeat_ms
- Turn on the clocks first before reset operation in start & restart callbacks
- Added checks in restart callback before turning ON clocks/resets
- Dropped udelay after every ping operation
- Added comments

v2->v3
- Fixed dependency, ARCH_R9A09G011->ARCH_R9A09G057
- Added dependency for PM
- Added delay after de-assert operation as clks are halted temporarily
  after de-assert operation
- Clearing WDTSR register

v1->v2
- Included RB tag for binding patch
- Fixed review comments from Claudiu
- Stopped using PM runtime calls in restart handler
- Dropped rstc deassert from probe

Cheers,
Prabhakar
