Signed-off-by: Chris Zhong --- Changes in v9: - update the subject and description Changes in v8: - set vdd_gpu to 1.0v during suspend - add regulator-on-in-suspend before set suspend voltage Changes in v7: - add regulator-state-mem sub node for suspend Changes in v6: None Changes in v5: None Changes in v4: None Changes in v3: None Changes in v2: None arch/arm/boot/dts/rk3288-evb-rk808.dts | 51 +++++++++++++++++++++++++++++++++- 1 file changed, 50 insertions(+), 1 deletion(-) diff --git a/arch/arm/boot/dts/rk3288-evb-rk808.dts b/arch/arm/boot/dts/rk3288-evb-rk808.dts index d8c775e6..742bd89 100644 --- a/arch/arm/boot/dts/rk3288-evb-rk808.dts +++ b/arch/arm/boot/dts/rk3288-evb-rk808.dts @@ -31,7 +31,7 @@ interrupt-parent = <&gpio0>; interrupts = <4 IRQ_TYPE_LEVEL_LOW>; pinctrl-names = "default"; - pinctrl-0 = <&pmic_int>; + pinctrl-0 = <&pmic_int &global_pwroff>; rockchip,system-power-controller; wakeup-source; #clock-cells = <1>; @@ -50,6 +50,9 @@ regulator-min-microvolt = <750000>; regulator-max-microvolt = <1350000>; regulator-name = "vdd_arm"; + regulator-state-mem { + regulator-off-in-suspend; + }; }; vdd_gpu: DCDC_REG2 { @@ -58,12 +61,20 @@ regulator-min-microvolt = <850000>; regulator-max-microvolt = <1250000>; regulator-name = "vdd_gpu"; + regulator-state-mem { + regulator-on-in-suspend; + regulator-suspend-microvolt = <1000000>; + }; }; vcc_ddr: DCDC_REG3 { regulator-always-on; regulator-boot-on; regulator-name = "vcc_ddr"; + regulator-suspend-mem-enabled; + regulator-state-mem { + regulator-on-in-suspend; + }; }; vcc_io: DCDC_REG4 { @@ -72,6 +83,10 @@ regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-name = "vcc_io"; + regulator-state-mem { + regulator-on-in-suspend; + regulator-suspend-microvolt = <3300000>; + }; }; vccio_pmu: LDO_REG1 { @@ -80,6 +95,10 @@ regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-name = "vccio_pmu"; + regulator-state-mem { + regulator-on-in-suspend; + regulator-suspend-microvolt = <3300000>; + }; }; vcc_tp: LDO_REG2 { @@ -88,6 +107,9 @@ regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-name = "vcc_tp"; + regulator-state-mem { + regulator-off-in-suspend; + }; }; vdd_10: LDO_REG3 { @@ -96,6 +118,10 @@ regulator-min-microvolt = <1000000>; regulator-max-microvolt = <1000000>; regulator-name = "vdd_10"; + regulator-state-mem { + regulator-on-in-suspend; + regulator-suspend-microvolt = <1000000>; + }; }; vcc18_lcd: LDO_REG4 { @@ -104,6 +130,9 @@ regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; regulator-name = "vcc18_lcd"; + regulator-state-mem { + regulator-off-in-suspend; + }; }; vccio_sd: LDO_REG5 { @@ -112,6 +141,9 @@ regulator-min-microvolt = <1800000>; regulator-max-microvolt = <3300000>; regulator-name = "vccio_sd"; + regulator-state-mem { + regulator-off-in-suspend; + }; }; vdd10_lcd: LDO_REG6 { @@ -120,6 +152,9 @@ regulator-min-microvolt = <1000000>; regulator-max-microvolt = <1000000>; regulator-name = "vdd10_lcd"; + regulator-state-mem { + regulator-off-in-suspend; + }; }; vcc_18: LDO_REG7 { @@ -128,6 +163,11 @@ regulator-min-microvolt = <1800000>; regulator-max-microvolt = <1800000>; regulator-name = "vcc_18"; + regulator-suspend-mem-microvolt = <1800000>; + regulator-state-mem { + regulator-on-in-suspend; + regulator-suspend-microvolt = <1800000>; + }; }; vcca_codec: LDO_REG8 { @@ -136,18 +176,27 @@ regulator-min-microvolt = <3300000>; regulator-max-microvolt = <3300000>; regulator-name = "vcca_codec"; + regulator-state-mem { + regulator-off-in-suspend; + }; }; vcc_wl: SWITCH_REG1 { regulator-always-on; regulator-boot-on; regulator-name = "vcc_wl"; + regulator-state-mem { + regulator-on-in-suspend; + }; }; vcc_lcd: SWITCH_REG2 { regulator-always-on; regulator-boot-on; regulator-name = "vcc_lcd"; + regulator-state-mem { + regulator-off-in-suspend; + }; }; }; }; -- 1.9.1
