watchdog: renesas-wdt: Add support for WDIOF_CARDRESET This patch adds the WDIOF_CARDRESET support for the Renesas platform watchdog, to know if the board reboot is due to a watchdog reset. This is done via the WOVF bit (bit 4) of the RWTCSRA register, which indicates if RWTCNT overflowed, triggering the reset in last boot.
