Subject: [PATCH v4 00/10] handling all DM watchdogs in watchdog_reset()
Date: Mon, 2 Aug 2021 17:00:06 +0200 [thread overview]
Message-ID: <20210802150016.588750-1-rasmus.villemoes@prevas.dk> (raw)
This series is an attempt at expanding the wdt-uclass provided
watchdog_reset() to handle all DM watchdogs, not just the first
one. Some of the ad hoc work done for the first DM watchdog in
initr_watchdog() is now moved to a .pre_probe hook so it is
automatically done for all devices.
It also includes a patch adding a driver for a gpio-petted watchdog
device (and a sandbox test of that) - it is included here because that
also gives a relatively easy way to have more than one (kind of)
watchdog device in the sandbox, which is then used at the end to test
that watchdog_reset() behaves as expected.
v2 here: https://lore.kernel.org/u-boot/20210527220017.1266765-1-rasmus.villemoes@prevas.dk/
v3 here: https://lore.kernel.org/u-boot/20210702124510.124401-1-rasmus.villemoes@prevas.dk/
Changes in v4:
- Do not make init_watchdog_dev() into a .post_probe hook, but call it
from within the probing loop in initr_watchdog().
Rasmus Villemoes (10):
watchdog: wdt-uclass.c: use wdt_start() in wdt_expire_now()
watchdog: wdt-uclass.c: introduce struct wdt_priv
watchdog: wdt-uclass.c: neaten UCLASS_DRIVER definition
watchdog: wdt-uclass.c: refactor initr_watchdog()
watchdog: wdt-uclass.c: keep track of each device's running state
sandbox: disable CONFIG_WATCHDOG_AUTOSTART
watchdog: wdt-uclass.c: handle all DM watchdogs in watchdog_reset()
watchdog: add gpio watchdog driver
sandbox: add test of wdt_gpio driver
sandbox: add test of wdt-uclass' watchdog_reset()
