Subject: [PATCH 0/3] watchdog: ma35d1: Add support for MA35D1 Watchdog
Date: Thu, 23 Jul 2026 14:07:51 +0800 [thread overview]
Message-ID: <20260723060755.1596858-1-zychennvt@gmail.com> (raw)
This patch series introduces watchdog timer support for the Nuvoton MA35D1
SoC platform.
The MA35D1 watchdog timer hardware provides a programmable countdown timer
capable of triggering a system reset upon timeout expiration or generating
an interrupt to wake up the system from low-power states.
Key features supported in this driver:
- Standard watchdog operations (start, stop, ping, set_timeout).
- Boot status detection to identify watchdog reset events (WDIOF_CARDRESET).
- Power management support including suspend/resume and wakeup functionality.
Series breakdown:
- Patch 1: Add DT binding documentation for Nuvoton MA35D1 watchdog.
- Patch 2: Add the watchdog driver implementation for MA35D1.
- Patch 3: Add the watchdog node in the MA35D1 SoC DeviceTree file.
Testing:
- Tested on the Nuvoton MA35D1 development board using standard watchdog
test utilities (e.g., watchdog-test from tools/testing/selftests/watchdog).
