From 33d2e46591ef9e7805cfea8ed880d20b7bbcee7e Mon Sep 17 00:00:00 2001 From: Alison Wang Date: Fri, 26 Dec 2014 13:14:01 +0800 Subject: 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.
