watchdog: rti_wdt: Add 10% safety margin to clock frequency

2022-03-08T08:08:09Z

When running against RC_OSC_32k, the watchdog may suffer from running faster than expected, expiring earlier. The Linux kernel adds a 10% margin to the timeout calculation by slowing down the read clock rate accordingly. Do the same here, also to have comparable preset values for both drivers. Along this, fix the name of the local var holding to frequency - in Hz, not kHz. Signed-off-by: Jan Kiszka Signed-off-by: Stefan Roese

watchdog: armada_37xx: Probe driver also when watchdog is already running

2022-03-08T08:08:09Z

If Armada 37xx watchdog is started before U-Boot then CNTR_CTRL_ACTIVE bit is set, U-Boot armada-37xx-wdt.c driver fails to initialize and so U-Boot is unable to use or kick this watchdog. Do not check for CNTR_CTRL_ACTIVE bit and always initialize watchdog. Same behavior is implemented in Linux kernel driver. This change allows to activate watchdog in firmware which loads U-Boot.

drivers: watchdog: wdt-uclass.c: add a property u-boot, noautostart

2022-03-08T08:08:00Z

Since commit 492ee6b8d0e7 ("watchdog: wdt-uclass.c: handle all DM watchdogs in watchdog_reset()"), all the watchdog are started when the config WATCHDOG_AUTOSTART. To avoid a binary choice none/all, a property u-boot,noautostart may be added in the watchdog node of the u-boot device tree to not autostart this watchdog.

watchdog: add sl28cpld watchdog driver

2022-02-28T06:29:35Z

The watchdog timer is part of the sl28cpld management controller. The watchdog timer usually supervises the bootloader boot-up and if it bites the failsafe bootloader will be activated. Apart from that it supports the usual board level reset and one SMARC speciality: driving the WDT_TIMEOUT# signal. Signed-off-by: Michael Walle Reviewed-by: Priyanka Jain

watchdog: armada_37xx: Convert to official DT bindings

2022-02-17T13:17:07Z

Official DT bindings have only one reg property: watchdog address space. Convert armada-37xx-wdt.c driver to offical DT bindings and access sel_reg register via MVEBU_REGISTER() macro, as its value (required by U-Boot driver) is not in DT yet. In later stage can be driver cleaned to not use it. This change would allow U-Boot to use A3720 watchdog DTS structure from Linux kernel. Signed-off-by: Pali Rohár Reviewed-by: Stefan Roese
