From a4f203512be974dbd7425f8f1d3d40720bf36997 Mon Sep 17 00:00:00 2001 From: John Crispin Date: Mon, 30 Apr 2012 19:30:46 +0200 Subject: [PATCH] OF: MTD: make plat_nand loadable from DT This patch sets the of_match_table field inside plat_nand's platform_driver. We also add a struct mtd_part_parser_data pointer to make sure of_part parsing works. If an arch wants to support plat_nand via DT it needs to setup the platform_nand_data and hook it into the platform_device.
