From 7c8b77f81552c2b0e5d9c560da70bc4149ce66a5 Mon Sep 17 00:00:00 2001 From: Enric Balletbo i Serra Date: Mon, 16 Apr 2018 11:39:57 -0300 Subject: [PATCH] arm64: defconfig: Enable Rockchip io-domain driver MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Heiko Stübner justified pretty well the change in commit e330eb86ba0b ("ARM: multi_v7_defconfig: enable Rockchip io-domain driver"). This change is also needed for arm64 rockchip boards, so, do the same for arm64. The io-domain driver is necessary to notify the soc about voltages changes happening on supplying regulators. Probably the most important user right now is the mmc tuning code, where the soc needs to get notified when the voltage is dropped to the 1.8V point. As this option is necessary to successfully tune UHS cards etc, it should get built in. Otherwise, tuning will fail with, dwmmc_rockchip fe320000.dwmmc: All phases bad! mmc0: tuning execution failed: -5 Signed-off-by: Enric Balletbo i Serra Acked-by: Robin Murphy Signed-off-by: Heiko Stuebner --- arch/arm64/configs/defconfig | 2 ++ 1 file changed, 2 insertions(+) diff --git a/arch/arm64/configs/defconfig b/arch/arm64/configs/defconfig index bdd594387232..7e3b3f0484b9 100644 --- a/arch/arm64/configs/defconfig +++ b/arch/arm64/configs/defconfig @@ -332,6 +332,8 @@ CONFIG_GPIO_XGENE_SB=y CONFIG_GPIO_PCA953X=y CONFIG_GPIO_PCA953X_IRQ=y CONFIG_GPIO_MAX77620=y +CONFIG_POWER_AVS=y +CONFIG_ROCKCHIP_IODOMAIN=y CONFIG_POWER_RESET_MSM=y CONFIG_POWER_RESET_XGENE=y CONFIG_POWER_RESET_SYSCON=y -- GitLab
