Subject: [PATCH v1 2/8] watchdog: f71808e_wdt: indicate WDIOF_CARDRESET support in watchdog_info.options
Date: Thu, 11 Jun 2020 21:17:43 +0200
Message-ID: <20200611191750.28096-3-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20200611191750.28096-1-a.fatoum@pengutronix.de>

The driver supports populating bootstatus with WDIOF_CARDRESET, but so
far userspace couldn't portably determine whether absence of this flag
meant no watchdog reset or no driver support. Or-in the bit to fix this.
