From 583f958b8a23343c904ec0790c25c96f5f82d409 Mon Sep 17 00:00:00 2001 From: Bartlomiej Zolnierkiewicz Date: Thu, 2 Oct 2014 18:10:06 +0200 Subject: [PATCH] ARM: dts: fix MMC2 regulators for Exynos5420 Arndale Octa board Regulators for MMC2 (SD card) are PVDD_TFLASH_2V8 (LDO19) for vmmc and PVDD_APIO_MMCOFF_2V8 (LDO13) for vqmmc. Currently the device tree entry for MMC2 uses PVDD_PRE_1V8 (LDO10) for vmmc and vqmmc is not specified. Fix it. Without this patch: - "mmc: dw_mmc: use mmc_regulator_get_supply to handle regulators" patch causes a SD card detection to fail - "mmc: dw_mmc: Support voltage changes" patch causes a boot hang This patch fixes both above problems.
