Subject: [PATCH 4/5] Watchdog/i.MX: make the watchdog driver a regular driver
Date: Tue, 23 Jun 2015 14:58:03 +0200	[thread overview]
Message-ID: <1435064284-8015-5-git-send-email-jbe@pengutronix.de> (raw)
In-Reply-To: <1435064284-8015-1-git-send-email-jbe@pengutronix.de>

Even if the driver for the internal watchdog unit is disabled, it gets
enabled again silently if we select an i.MX platform.

This change compiles the driver on user demand only. Barebox can handle one
watchdog and one reset source. This change enables a user to select a
different one if the built-in unit cannot be used due to hardware issues like
power management and voltage changes the internal watchdog cannot reset
correctly.
