From 626a645eb75415255aad3162f4da3f6988f0c8ec Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Tue, 12 Feb 2013 18:15:33 +0100 Subject: ARM: shmobile: streamline mackerel SD and MMC devices This patch fixes the following issues with SD and MMC interfaces on mackerel: 1. replace custom card-detection functions with standard GPIO CD API 2. resources don't have to be numbered 3. add SDHI interrupt names 4. remove OCR masks, where regulators are used 5. only specify SDHI CD interrupts on interfaces where a CD pin is present - SDHI0 6. don't instantiate an MMCIF device and initialise MMCIF pins if SDHI1 is selected Signed-off-by: Guennadi Liakhovetski Signed-off-by: Simon Horman --- arch/arm/mach-shmobile/board-mackerel.c | 113 ++++++++++++++++---------------- 1 file changed, 57 insertions(+), 56 deletions(-) (limited to 'arch/arm/mach-shmobile/board-mackerel.c') diff --git a/arch/arm/mach-shmobile/board-mackerel.c b/arch/arm/mach-shmobile/board-mackerel.c index 336ccb4a0f2a..fb058c763a7d 100644 --- a/arch/arm/mach-shmobile/board-mackerel.c +++ b/arch/arm/mach-shmobile/board-mackerel.c @@ -963,15 +963,6 @@ static struct platform_device nand_flash_device = { }, };
