watchdog timer.

watchdog: Add pm8916 watchdog driver

2018-12-22T11:15:33+00:00

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

2018-10-13T13:19:39+00:00

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.

In those cases that depend on architectures we have already removed,
they can be omitted.

watchdog: Add Nuvoton NPCM watchdog driver

2018-03-24T09:19:39+00:00

The Nuvoton NPCM750 has a watchdog implemented as a single register
inside the timer peripheral.

This driver exposes that watchdog as a standard watchdog device with
coarse timeout intervals, limited by the combination of prescaler and
counter that is provided by the hardware. The calculation is taken from
the Nuvoton vendor tree.

The watchdog is left running if a bootloader had it going. The rate is
the one specified in the device tree, or the default value (obtained
from the datasheet).

There is a pre-timeout IRQ that is wired up. This timeout always occurs
1024 clocks before the timeout.
