More patches (unsent or sent and pending review or revision) can be found here[1]. This series adds support for the top reset generation unit (TOPRGU) found on the MediaTek MT6735 SoC. TOPRGU generates several reset signals and provides watchdog timer functionality.

It appears to confuse "reset" (which is triggered by writing a specific value into the WDT_SWRST register) with the action to be taken when the watchdog triggers. The code below does not trigger the watchdog; it is supposed to trigger a soft reset, which should be independent of the above. So this needs more explanation than just "issue a system reset instead of an IRQ", because that is presumably not supposed to be what is happening when writing into the WDT_SWRST register. The above also doesn't explain what is supposed to happen if WDT_MODE_EXRST_EN is not set, adding more to the confusion.
