From 78800558d104e003f9ae92e0107f1de39cf9de9f Mon Sep 17 00:00:00 2001 From: Alex Smith Date: Thu, 3 Dec 2015 12:02:22 +0000 Subject: MIPS: dts: jz4780/ci20: Add NEMC, BCH and NAND device tree nodes Add device tree nodes for the NEMC and BCH to the JZ4780 device tree, and make use of them in the Ci20 device tree to add a node for the board's NAND. Note that since the pinctrl driver is not yet upstream, this includes neither pin configuration nor busy/write-protect GPIO pins for the NAND. Use of the NAND relies on the boot loader to have left the pins configured in a usable state, which should be the case when booted from the NAND.
