watchdog: Delete the cpu5wdt driver

2024-11-05T09:04:39+00:00

This driver has a number of issues (accesses arbitrary I/O ports
without identifying the hardware, doesn't document what hardware it
supports, suspiciously inconsistent locking model, doesn't implement
WDIOC_SETTIMEOUT, potential integer overflow...)

The driver was added in 2003 and there's no evidence that it has any
recent user, all changes seem to be tree-wide, subsystem-wide, or the
result of static code analysis. So I believe we should simply drop
this legacy piece of code.

watchdog: Add support for Airoha EN7851 watchdog

2024-11-05T09:04:39+00:00

Add support for Airoha EN7851 watchdog. This is a very basic watchdog
with no pretimeout support, max timeout is 28 seconds and it ticks based
on half the SoC BUS clock.

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.
