Subject: [PATCH 4.4 04/33] watchdog: f71808e_wdt: indicate WDIOF_CARDRESET support in watchdog_info.options
Date: Mon, 24 Aug 2020 10:31:00 +0200	[thread overview]
Message-ID: <20200824082346.743864011@linuxfoundation.org> (raw)
In-Reply-To: <20200824082346.498653578@linuxfoundation.org>

From: Ahmad Fatoum <a.fatoum@pengutronix.de>

[ Upstream commit e871e93fb08a619dfc015974a05768ed6880fd82 ]

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.
