watchdog: mlx-wdt: introduce a watchdog driver for Mellanox systems.

2019-03-02T14:28:20Z

Introduce watchdog driver for a various range of Mellanox Ethernet and Infiniband switch systems. Watchdog driver for Mellanox watchdog devices, implemented in programmable logic device. Main and auxiliary watchdog devices can exist on the same system. There are several actions that can be defined in the watchdog: system reset, start fans on full speed and increase a counter. The last 2 actions are performed without a system reset. Actions without reset are provided for auxiliary watchdog devices, which is optional. Access to HW registers is performed through generic regmap interface. There are 2 types of HW watchdog implementations. Type 1: actual HW timeout can be defined as power of 2 msec. e.g. timeout 20 sec will be rounded up to 32768 msec.; maximum timeout period is 32 sec (32768 msec.); get time-left isn't supported Type 2: actual HW timeout is defined in sec. and it's the same as user-defined timeout; maximum timeout is 255 sec; get time-left is supported; Watchdog driver is probed from the common mlx_platform driver.

watchdog: stpmic1: Add STPMIC1 watchdog driver

The STPMIC1 PMIC embeds a watchdog which is disabled by default. As soon as the watchdog is started, it must be refreshed periodically otherwise the PMIC goes off. Signed-off-by: Pascal Paillet Reviewed-by: Guenter Roeck Signed-off-by: Lee Jones

watchdog: Add pm8916 watchdog driver

2018-12-22T11:15:33Z

The PM816 module is a versatile PMIC with many diverse functions integrated, including, a watchdog. This watchdog is subcomponent of the PON (Power On) peripheral, in the same way as pwrkey/resin buttons. It works with two timers (2-stages), the first one generates an IRQ to the main SoC (APQ8016/MSM8916), the second one performs the reset. This driver expects the following device hierarchy: [pm8916]->[pm8916-pon]->[pm8916-wdt] It uses the pm8916 regmap to access PM8916 registers.

watchdog: Add support for Armada 37xx CPU watchdog

2018-10-13T13:19:39Z

This adds support for the CPU watchdog found on Marvell Armada 37xx SoCs. There are 4 counters which can be set as CPU watchdog counters. This driver uses the second counter (ID 1, counting from 0) as watchdog counter, and first counter (ID 0) to implement pinging on the second counter without the need to disable it. Since counters IDs 2 and 3 are enabled already before even U-Boot starts, this driver does not use them at all, for example by adding a device tree property for counter selection.
