From: Alison Wang Date: Fri, 26 Dec 2014 05:14:01 +0000 (+0800) Subject: ls102xa: fdt: Disable QSPI and DSPI in NOR/NAND/SD boot X-Git-Tag: v2015.04-rc1~44 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=33d2e46591ef9e7805cfea8ed880d20b7bbcee7e;p=platform%2Fkernel%2Fu-boot.git ls102xa: fdt: Disable QSPI and DSPI in NOR/NAND/SD boot As QSPI/DSPI and IFC are pin multiplexed, QSPI and DSPI are only enabled in QSPI boot, and disabled in other boot modes. IFC is enabled in NOR/NAND/SD boot, and disabled in QSPI boot. This patch will add fdt support for the above rules.
