From 74b94e6b8013dcec6782b2fca4abf301f5aa5245 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Fri, 21 Jun 2019 17:44:54 +0200 Subject: ARM: dts: exynos: Use proper regulator for eMMC memory on Arndale Octa The eMMC memory is supplied by LDO18 (PVDD_EMMC_1V8) and buck10 (PVDD_EMMCF_2V8), not by LDO10. The LDO10 (PVDD_PRE_1V8) supplies instead VDDP_MMC pin of eMMC host interface and it is already marked as always on. This change only properly models the hardware and reflects in usage of regulators. There is no functional change because: 1. LDO18 cannot be turned off (e.g. by lack of consumers) because in off mode it is controlled by LDO18EN pin, which is pulled up by always-on regulator LDO2 (PVDD_APIO_1V8). 2. LDO10 is marked as always on so removing its consumer will not have effect.
