watchdog: ROHM BD96801 PMIC WDG driver

2024-06-27T08:24:45+00:00

Introduce driver for WDG block on ROHM BD96801 scalable PMIC.

This driver only supports watchdog with I2C feeding and delayed
response detection. Whether the watchdog toggles PRSTB pin or
just causes an interrupt can be configured via device-tree.

The BD96801 PMIC HW supports also window watchdog (too early
feeding detection) and Q&A mode. These are not supported by
this driver.

watchdog: ar7_wdt: remove driver to prepare for platform removal

2023-10-19T08:34:09+00:00

AR7 is going to be removed from the Kernel, so remove its watchdog
support. This allows us to remove the platform because this driver
includes a platform specific header.

watchdog: xilinx_wwdt: Add Versal window watchdog support

2023-06-26T12:30:06+00:00

Versal watchdog driver uses window watchdog mode. Window watchdog
timer(WWDT) contains closed(first) and open(second) window with
32 bit width. Write to the watchdog timer within predefined window
periods of time. This means a period that is not too soon and a
period that is not too late. The WWDT has to be restarted within
the open window time. If software tries to restart WWDT outside of
the open window time period, it generates a reset.

watchdog/pseries-wdt: initial support for H_WATCHDOG-based watchdog timers

2022-07-20T11:57:39+00:00

PAPR v2.12 defines a new hypercall, H_WATCHDOG.  The hypercall permits
guest control of one or more virtual watchdog timers.  The timers have
millisecond granularity.  The guest is terminated when a timer
expires.

This patch adds a watchdog driver for these timers, "pseries-wdt".

pseries_wdt_probe() currently assumes the existence of only one
platform device and always assigns it watchdogNumber 1.  If we ever
expose more than one timer to userspace we will need to devise a way
to assign a distinct watchdogNumber to each platform device at device
registration time.
