Watchdog: Add marvell GTI watchdog driver

2023-08-13T12:29:49+00:00

This patch add support for Marvell GTI watchdog. Global timer unit (GTI) support hardware watchdog timer. Software programs watchdog timer to generate interrupt on first timeout, second timeout is configured to be ignored and system reboots on third timeout.

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.

watchdog: Add Renesas RZ/N1 Watchdog driver

2022-05-21T08:09:31+00:00

This is a driver for the standard WDT on the RZ/N1 devices. This WDT has very limited timeout capabilities. However, it can reset the device. To do so, the corresponding bits in the SysCtrl RSTEN register need to be enabled. This is not done by this driver.
