Subject: [PATCH RESEND 03/15] ARM: clps711x: autcpu12: Move LCD DPOT definitions to board file
Date: Wed,  5 Jun 2013 09:59:11 +0400	[thread overview]
Message-ID: <1370411967-29451-4-git-send-email-shc_work@mail.ru> (raw)
In-Reply-To: <1370411967-29451-1-git-send-email-shc_work@mail.ru>

We do not have driver for Up/Down digital potentiometer (DPOT), so
just define pins as GPIOs and export these pins to user.
