Subject: [PATCH 14/33] pcmcia: soc_common: add CF socket state helper
Date: Mon, 29 Aug 2016 11:25:17 +0100 [thread overview]
Message-ID: <E1beJkj-0000n4-71@rmk-PC.armlinux.org.uk> (raw)
In-Reply-To: <20160829102328.GA28796@n2100.armlinux.org.uk>
Add a helper to get the voltage state of CF sockets, where the voltage
sense pins are not wired up. Switch assabet and cerf to use this
helper.
