From b756dc48b7645f8753516c49594157e45ba3e4f1 Mon Sep 17 00:00:00 2001 From: Tomasz Figa Date: Sun, 14 Sep 2014 02:10:35 +0900 Subject: ARM: dts: Fix pull setting in sd4_width8 pin group for exynos4x12 The group has the samsung,pin-pud property set to 4, which is not a correct value. This patch fixes this by replacing it with 3, which is the correct value for pull-up.

Fix it. [ Please note that cpu_v7_do_[suspend,resume] code in proc-v7.S already correctly checks for CONFIG_ARM_CPU_SUSPEND, same is true for functions for other architectures. ] This fix is needed for decoupling suspend/resume and advanced cpuidle support on Exynos platform (next patch fixes build for config with CONFIG_PM_SLEEP=n and CONFIG_ARM_EXYNOS_CPUIDLE=y).
