Subject: [PATCH v4 0/2] Add drivers for Intel Keem Bay SoC watchdog
Date: Thu, 17 Dec 2020 02:32:46 +0800
Message-ID: <> (raw)

From: Vijayakannan Ayyathurai <>


This patch set adds the watchdog timer driver support for Intel Keem Bay Soc.

Patch 2 holds the driver and Patch 1 holds the Device Tree
binding documentation.

This driver was tested on the Keem Bay evaluation module board.

Thank you,

Changes since v3:
 - Fix pretimeout clear, when user attempt in the below sequence.
	- set pretimeout
	- clear pretimeout
	- set timeout to some other value
 - Cleanup the ping variable usage in the driver.
 - Add keembay_wdt_set_timeout_reg function.
 - Cleanup the keembay_wdt_th_isr function.
 - Rebase the driver with 5.10-rc7 tag.

Changes since v2:
 - Remove reduntant write to TIM_WATCHDOG as per Guenter.
 - Rebase the driver with 5.10-rc5 tag.

Changes since v1:
 - Fix indentation error in the dt-bindings file.
 - Use true/false in the second arg of keembay_wdt_set_timeout_reg().
 - Fix the watchdog start sequence.
 - Avoid reduntant timeout register setting.
 - Remove min usage to find actual time at keembay_wdt_set_timeout().
 - Remove timeout configuration boundary check at
 - Use devm_watchdog_register_device() for wdt registration, which
   eventually supports driver unload functionality as well.
