watchdog: armada_37xx_wdt: check the return value of devm_ioremap() in armada_37xx_wdt_probe()

2022-08-17T13:15:57+00:00

[ Upstream commit 2d27e52841092e5831dd41f313028c668d816eb0 ]

The function devm_ioremap() in armada_37xx_wdt_probe() can fail, so
its return value should be checked.

watchdog: sp5100_tco: Fix a memory leak of EFCH MMIO resource

2022-08-17T13:15:57+00:00

[ Upstream commit c6d9c0798ed366a09a9e53d71edcd2266e34a6eb ]

Unlike release_mem_region(), a call to release_resource() does not
free the resource, so it has to be freed explicitly to avoid a memory
leak.

watchdog: f71808e_wdt: Add check for platform_driver_register

[ Upstream commit 97d5ec548150764946f38632e62e79759832b54b ]

As platform_driver_register() could fail, it should be better
to deal with the return value in order to maintain the code
consisitency.

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

of_parse_phandle() returns a node pointer with refcount
incremented, we should use of_node_put() on it when done.
Add  missing of_node_put() in some error paths.

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.

watchdog: wdat_wdt: Stop watchdog when rebooting the system

2022-05-21T08:09:30+00:00

Executing reboot command several times on the machine "Dell
PowerEdge R740", UEFI security detection stopped machine
with the following prompt:

UEFI0082: The system was reset due to a timeout from the watchdog
timer. Check the System Event Log (SEL) or crash dumps from
Operating Sysstem to identify the source that triggered the
watchdog timer reset. Update the firmware or driver for the
identified device.

iDRAC has warning event: "The watchdog timer reset the system".

This patch fixes this issue by adding the reboot notifier.
