From 6f11840d0ccc43bf0a8f0d06c4a43a8ccce6dd73 Mon Sep 17 00:00:00 2001 From: Pekon Gupta Date: Tue, 28 Jan 2014 11:42:40 +0530 Subject: ARM: OMAP2+: gpmc: fix: DT NAND child nodes not probed when MTD_NAND is built as module commit 6b187b21c92b6e2c7e8ef0b450181c37a3f31681 upstream. Fixes: commit bc6b1e7b86f5d8e4a6fc1c0189e64bba4077efe0 ARM: OMAP: gpmc: add DT bindings for GPMC timings and NAND OMAP SoC(s) depend on GPMC controller driver to parse GPMC DT child nodes and register them platform_device for NAND driver to probe later. However this does not happen if generic MTD_NAND framework is built as module (CONFIG_MTD_NAND=m). Therefore, when MTD/NAND and MTD/NAND/OMAP2 modules are loaded, they are unable to find any matching platform_device and remain un-binded. This causes on board NAND flash to remain un-detected. This patch causes GPMC controller to parse DT nodes when CONFIG_MTD_NAND=y || CONFIG_MTD_NAND=m Signed-off-by: Pekon Gupta Signed-off-by: Tony Lindgren Signed-off-by: Greg Kroah-Hartman --- arch/arm/mach-omap2/gpmc.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch') diff --git a/arch/arm/mach-omap2/gpmc.c b/arch/arm/mach-omap2/gpmc.c index 6c4da1254f5..dc4ccdbde06 100644 --- a/arch/arm/mach-omap2/gpmc.c +++ b/arch/arm/mach-omap2/gpmc.c @@ -1335,7 +1335,7 @@ static void __maybe_unused gpmc_read_timings_dt(struct device_node *np, of_property_read_bool(np, "gpmc,time-para-granularity"); } -#ifdef CONFIG_MTD_NAND +#if IS_ENABLED(CONFIG_MTD_NAND) static const char * const nand_ecc_opts[] = { [OMAP_ECC_HAMMING_CODE_DEFAULT] = "sw", -- cgit v1.2.3
