From 67e7607fcdf1fad10e9f183424e709c59713e45d Mon Sep 17 00:00:00 2001 From: Jerome Brunet Date: Thu, 31 Aug 2017 15:52:20 +0200 Subject: ARM64: dts: meson: add mmc clk gate pins Add the pinctrl to switch mmc clk pins in gpio (pulled down) mode. This is necessary to be able to gate the clk outside of the SoC while keeping it running in the controller Signed-off-by: Jerome Brunet Signed-off-by: Kevin Hilman --- arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts | 8 +++++--- 1 file changed, 5 insertions(+), 3 deletions(-) (limited to 'arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts') diff --git a/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts b/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts index a12303becab4..1ffa1c238a72 100644 --- a/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts +++ b/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts @@ -50,7 +50,7 @@ / { compatible = "hardkernel,odroid-c2", "amlogic,meson-gxbb"; model = "Hardkernel ODROID-C2"; - + aliases { serial0 = &uart_AO; }; @@ -253,7 +253,8 @@ &sd_emmc_b { status = "okay"; pinctrl-0 = <&sdcard_pins>; - pinctrl-names = "default"; + pinctrl-1 = <&sdcard_clk_gate_pins>; + pinctrl-names = "default", "clk-gate"; bus-width = <4>; cap-sd-highspeed; @@ -271,7 +272,8 @@ &sd_emmc_c { status = "okay"; pinctrl-0 = <&emmc_pins>; - pinctrl-names = "default"; + pinctrl-1 = <&emmc_clk_gate_pins>; + pinctrl-names = "default", "clk-gate"; bus-width = <8>; max-frequency = <200000000>; -- cgit v1.2.3
