watchdog: bcm6345: allow to use this driver on arm bcm63158

watchdog: bcm6345: switch to raw I/O functions

2019-02-09T12:50:50Z

This driver is used on several big endian mips board. So we could use raw I/O function instead of forcing big endian access. Signed-off-by: Philippe Reynes Reviewed-by: Daniel Schwierzeck

watchdog: armada_37xx: Fix compliance with kernel's driver

2019-01-21T10:39:49Z

The Armada 37xx watchdog driver was recently accepted for mainline kernel by watchdog subsystem maintainer, but the driver works a little different than the one in U-Boot. This patch fixes this. In the previous implementation there was a tiny period of time when the watchdog was disabled and the system was vulnerables - this was during pinging, which was done by disabling, setting, and enabling the counter. Now pinging is done without disabling the watchdog. We use 2 counters: Counter 1 is the watchdog counter - on expiry, the system is reset. Counter 0 is used to reset Counter 1 to start counting from the set timeout again. So Counter 1 is set to be reset on Counter 0 expiry event event and pinging is done by forcing an immediate expiry event on Counter 0. Signed-off-by: Marek Behún Signed-off-by: Stefan Roese

watchdog: imx: add config to disable wdog reset

2019-01-01T13:12:18Z

Add Kconfig option WATCHDOG_RESET_DISABLE to disable watchdog reset in imx_watchdog driver, so that the watchdog will not be fed in u-boot if CONFIG_WATCHDOG_RESET_DISABLE is enabled. Signed-off-by: Xiaoliang Yang

watchdog: driver support for fsl-lsch2

2019-01-01T13:12:18Z

Support watchdog driver for fsl-lsch2. It's disabled in default. If you want to use it, please enable CONFIG_IMX_WATCHDOG. Define CONFIG_WATCHDOG_TIMEOUT_MSECS to set watchdog timeout. Signed-off-by: Xiaoliang Yang

drivers: watchdog: add a DM driver for the MPC8xx watchdog

2018-12-03T15:44:10Z

This patch adds a DM driver for the MPC8xx watchdog. Basically, the watchdog is enabled by default from the start and SYPCR register has to be writen once to set the timeout and/or deactivate the watchdog. Once written, it cannot be written again. It means that wdt_stop() can be called before wdt_start() to stop the watchdog, but cannot be called if wdt_start() has been called. Signed-off-by: Christophe Leroy
