Subject: [PATCH 2/3] ARM: sa1100/assabet: switch to using gpio leds
Date: Mon, 29 Aug 2016 12:03:07 +0100	[thread overview]
Message-ID: <E1beKLL-000170-HH@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20160829110157.GE1041@n2100.armlinux.org.uk>

Switch over to using gpio leds now that we have the gpio driver for
the assabet board register in place.
