watchdog: aspeed: Add support for aspeed,reset-mask DT property

2023-10-29T18:45:11+00:00

This property allows the device-tree to specify how the Aspeed
watchdog timer's reset mask register(s) should be set, so that
peripherals can be individually exempted from (or opted in to) being
reset when the watchdog timer expires.

drivers: watchdog: marvell_gti: Program the max_hw_heartbeat_ms

2023-10-29T18:45:08+00:00

Program the max_hw_heartbeat_ms value so that the watchdog_pretimeout
worker is activated. This kernel worker thread makes sure to ping the
watchdog in case the userspace is unable to do so. This kernel worker
ping will be done only till the full watchdog timeout there by
maintaining the watchdog functionality in case of a real hang.

drivers: watchdog: marvell_gti: fix zero pretimeout handling

2023-10-29T18:45:08+00:00

When pretimeout is set to 0 then do not reprogram timer
with zero timeout, this will reset device immediately.
Also disable interrupt to stop pretimeout notification.

watchdog: marvell_gti: Replace of_platform.h with explicit includes

2023-10-29T18:45:07+00:00

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it was merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other and pull in various other headers. In
preparation to fix this, adjust the includes for what is actually needed.

of_platform.h isn't needed, but of.h was implicitly included by it (via
of_device.h).

watchdog: imx_sc_wdt: continue if the wdog already enabled

2023-10-29T18:45:07+00:00

if the wdog is already enabled, and try to enabled it again,
we should ignore the error and continue, rather than return
error.
