Subject: [U-Boot] [PATCH 1/4] arm: vf610: add NFC pin mux
Date: Wed,  6 Aug 2014 10:59:35 +0200	[thread overview]
Message-ID: <96ca140d8a275540c3068795307f531d9325b7fa.1407312577.git.stefan@agner.ch> (raw)
In-Reply-To: <cover.1407312577.git.stefan@agner.ch>

Add pin mux for NAND Flash Controller (NFC). NAND can be connected
using 8 or 16 data lines, this patch adds pin mux entries for all
16 data lines.
