From b31ce3041787b61f2dad39d2dcda5c4a81d10e2b Mon Sep 17 00:00:00 2001 From: Shawn Lin Date: Tue, 17 Oct 2017 11:38:04 +0800 Subject: [PATCH] arm64: dts: rockchip: correct vqmmc voltage for rk3399 platforms The vcc_sd or vcc_sdio used for IO voltage for sdmmc and sdio interface on rk3399 platform have a limitation that it can't be larger than 3.0v, otherwise it has a potential risk for the chip. Correct all of them. Fixes: 171582e00db1 ("arm64: dts: rockchip: add support for firefly-rk3399 board") Fixes: 2c66fc34e945 ("arm64: dts: rockchip: add RK3399-Q7 (Puma) SoM") Fixes: 8164a84cca12 ("arm64: dts: rockchip: Add support for rk3399 sapphire SOM") Cc: stable@vger.kernel.org Signed-off-by: Shawn Lin Tested-by: Klaus Goger Signed-off-by: Heiko Stuebner --- arch/arm64/boot/dts/rockchip/rk3399-firefly.dts | 4 ++-- arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi | 4 ++-- arch/arm64/boot/dts/rockchip/rk3399-sapphire.dtsi | 4 ++-- 3 files changed, 6 insertions(+), 6 deletions(-) diff --git a/arch/arm64/boot/dts/rockchip/rk3399-firefly.dts b/arch/arm64/boot/dts/rockchip/rk3399-firefly.dts index 7fd4bfcaa38e..fef82274a39d 100644 --- a/arch/arm64/boot/dts/rockchip/rk3399-firefly.dts +++ b/arch/arm64/boot/dts/rockchip/rk3399-firefly.dts @@ -371,10 +371,10 @@ regulator-always-on; regulator-boot-on; regulator-min-microvolt = <1800000>; - regulator-max-microvolt = <3300000>; + regulator-max-microvolt = <3000000>; regulator-state-mem { regulator-on-in-suspend; - regulator-suspend-microvolt = <3300000>; + regulator-suspend-microvolt = <3000000>; }; }; diff --git a/arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi b/arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi index 53ff3d191a1d..910628d18add 100644 --- a/arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3399-puma.dtsi @@ -325,12 +325,12 @@ vcc_sd: LDO_REG4 { regulator-name = "vcc_sd"; regulator-min-microvolt = <1800000>; - regulator-max-microvolt = <3300000>; + regulator-max-microvolt = <3000000>; regulator-always-on; regulator-boot-on; regulator-state-mem { regulator-on-in-suspend; - regulator-suspend-microvolt = <3300000>; + regulator-suspend-microvolt = <3000000>; }; }; diff --git a/arch/arm64/boot/dts/rockchip/rk3399-sapphire.dtsi b/arch/arm64/boot/dts/rockchip/rk3399-sapphire.dtsi index 6c30bb02210d..0f873c897d0d 100644 --- a/arch/arm64/boot/dts/rockchip/rk3399-sapphire.dtsi +++ b/arch/arm64/boot/dts/rockchip/rk3399-sapphire.dtsi @@ -315,10 +315,10 @@ regulator-always-on; regulator-boot-on; regulator-min-microvolt = <1800000>; - regulator-max-microvolt = <3300000>; + regulator-max-microvolt = <3000000>; regulator-state-mem { regulator-on-in-suspend; - regulator-suspend-microvolt = <3300000>; + regulator-suspend-microvolt = <3000000>; }; };
