Subject: [PATCH v4 0/3] Introduce EC-based watchdog
Date: Fri, 26 Jan 2024 09:57:18 +0000 [thread overview]
Message-ID: <20240126095721.782782-1-lma@chromium.org> (raw)
Chromeos devices are equipped with the embedded controller (EC)
that can be used as a watchdog. The following patches
updates the structures and definitions required to
communicate with EC-based watchdog and implements the
driver itself.
V1:https://patchwork.kernel.org/project/linux-watchdog/patch/20240117102450.4080839-1-lma@chromium.org/
V2:https://patchwork.kernel.org/project/linux-watchdog/list/?series=817925
V3:https://patchwork.kernel.org/project/linux-watchdog/list/?series=818036
Changelog
V3->V4:
* updated sizeof() argument with pointer dereference
* added cros_ec_wdt_id to the driver structure
* "mfd: cros_ec: Register EC-based watchdog subdevice"
has been already applied to the for-mfd-next
V2->V3:
* drop "-drv" from driver name
* use format #define<space>NAME<tab>value
V1->V2:
* Split into three patches
* Supplement the watchdog configuration with min/max timeouts
* Removed struct cros_ec_wdt_data and get aligned to watchdog framework
* Simplified suspend/resume callbacks
* Removed excessive log messages
* Reworked cros_ec_wdt_send_hang_detect() function to be more generic
* Usage of devm_* allowed to delete .remove module callback
* Changed MODULE_ALIAS to MODULE_DEVICE_TABLE
* Moved clearing bootstatus (on EC) to probe() and thanks to that
got rid of .shutdown() module callback
* Fixed/removed comments, removed unused includes and general cleanup
Best regards,
Lukasz
