The driver integrates with the Linux watchdog framework and supports: - Basic watchdog operations (start, stop, ping, set_timeout). - Programmable reset and interrupt intervals. - Automatic detection of the supported interrupt timer bit-width. - System reset via the watchdog restart handler. Changes in v2: - dt-bindings: - Drop redundant text "including supported properties..." from the commit message. - Clarify the relationship between ATCWDT200 IP and SoCs (AE350/Qilai) in the commit message. - Add missing type definition ($ref: uint32), enum constraint, and description for 'andestech,clock-source' property. - watchdog: atcwdt200: - Use devm_clk_get_enabled() instead of devm_clk_get() and clk_prepare_enable() - Drop unnecessary "andestech,qilai-wdt" compatible - Remove .owner assignment from platform_driver - Simplify resume error handling CL Wang (3): dt-bindings: watchdog: Add support for Andes ATCWDT200 watchdog: atcwdt200: Add driver for Andes ATCWDT200 MAINTAINERS: Add entry for Andes ATCWDT200 .../watchdog/andestech,ae350-wdt.yaml | 53 ++ MAINTAINERS | 6 + drivers/watchdog/Kconfig | 9 + drivers/watchdog/Makefile | 1 + drivers/watchdog/atcwdt200_wdt.c | 580 ++++++++++++++++++ 5 files changed, 649 insertions(+) create mode 100644 Documentation/devicetree/bindings/watchdog/andestech,ae350-wdt.yaml create mode 100644 drivers/watchdog/atcwdt200_wdt.c -- 2.34.1
