Add device tree node for ATC2603C PMIC and remove the 'fixed-3.1V' dummy regulator used for the uSD supply. Additionally, add 'SYSPWR' fixed regulator and provide cpu0 supply. Signed-off-by: Cristian Ciocaltea <cristian.ciocaltea@xxxxxxxxx> --- Please note the patch depends on the ATC260x PMIC support which is queued for merging in v5.13: https://lore.kernel.org/lkml/cover.1611653995.git.cristian.ciocaltea@xxxxxxxxx/ https://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd.git/log/?h=for-mfd-next&qt=range&q=a38fd8748464831584a19438cbb3082b5a2dab15..eac013a0b7041f5cfc8feedf429a767675350102 arch/arm/boot/dts/owl-s500-roseapplepi.dts | 132 ++++++++++++++++++++- 1 file changed, 126 insertions(+), 6 deletions(-) diff --git a/arch/arm/boot/dts/owl-s500-roseapplepi.dts b/arch/arm/boot/dts/owl-s500-roseapplepi.dts index ff91561ca99c..b8c5db2344aa 100644 --- a/arch/arm/boot/dts/owl-s500-roseapplepi.dts +++ b/arch/arm/boot/dts/owl-s500-roseapplepi.dts @@ -2,7 +2,7 @@ /* * Roseapple Pi * - * Copyright (C) 2020 Cristian Ciocaltea <cristian.ciocaltea@xxxxxxxxx> + * Copyright (C) 2020-2021 Cristian Ciocaltea <cristian.ciocaltea@xxxxxxxxx> */ /dts-v1/; @@ -27,20 +27,140 @@ memory@0 { reg = <0x0 0x80000000>; /* 2GB */ }; - /* Fixed regulator used in the absence of PMIC */ - sd_vcc: sd-vcc { + syspwr: regulator-5v0 { compatible = "regulator-fixed"; - regulator-name = "fixed-3.1V"; - regulator-min-microvolt = <3100000>; - regulator-max-microvolt = <3100000>; + regulator-name = "SYSPWR"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; regulator-always-on; }; }; +&cpu0 { + cpu0-supply = <&vdd_cpu>; +}; + &i2c0 { status = "okay"; pinctrl-names = "default"; pinctrl-0 = <&i2c0_pins>; + + atc260x: pmic@65 { + compatible = "actions,atc2603c"; + reg = <0x65>; + interrupt-parent = <&sirq>; + interrupts = <2 IRQ_TYPE_LEVEL_HIGH>; + + reset-time-sec = <6>; + + regulators { + compatible = "actions,atc2603c-regulator"; + + dcdc1-supply = <&syspwr>; + dcdc2-supply = <&syspwr>; + dcdc3-supply = <&syspwr>; + ldo1-supply = <&syspwr>; + ldo2-supply = <&syspwr>; + ldo3-supply = <&syspwr>; + ldo5-supply = <&syspwr>; + ldo6-supply = <&syspwr>; + ldo7-supply = <&syspwr>; + ldo8-supply = <&syspwr>; + ldo11-supply = <&syspwr>; + ldo12-supply = <&syspwr>; + switchldo1-supply = <&vcc>; + + vdd_cpu: dcdc1 { + regulator-name = "VDD_CPU"; + regulator-min-microvolt = <700000>; + regulator-max-microvolt = <1400000>; + regulator-always-on; + }; + + vddq: dcdc2 { + regulator-name = "VDDQ"; + regulator-min-microvolt = <1300000>; + regulator-max-microvolt = <2150000>; + regulator-always-on; + regulator-boot-on; + }; + + vcc: dcdc3 { + regulator-name = "VCC"; + regulator-min-microvolt = <2600000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + }; + + vcc_3v3: ldo1 { + regulator-name = "VCC_3V3"; + regulator-min-microvolt = <2600000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + }; + + avcc: ldo2 { + regulator-name = "AVCC"; + regulator-min-microvolt = <2600000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + }; + + vdd_1v8: ldo3 { + regulator-name = "VDD_1V8"; + regulator-min-microvolt = <1500000>; + regulator-max-microvolt = <2000000>; + regulator-always-on; + }; + + vcc_3v1: ldo5 { + regulator-name = "VCC_3V1"; + regulator-min-microvolt = <2600000>; + regulator-max-microvolt = <3300000>; + }; + + avdd: ldo6 { + regulator-name = "AVDD"; + regulator-min-microvolt = <700000>; + regulator-max-microvolt = <1400000>; + regulator-always-on; + }; + + sens_1v8: ldo7 { + regulator-name = "SENS_1V8"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + }; + + ldo8: ldo8 { + regulator-name = "LDO8"; + regulator-min-microvolt = <2300000>; + regulator-max-microvolt = <3300000>; + }; + + svcc: ldo11 { + regulator-name = "SVCC"; + regulator-min-microvolt = <2600000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + }; + + rtc_vdd: ldo12 { + regulator-name = "RTC_VDD"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + regulator-always-on; + }; + + sd_vcc: switchldo1 { + regulator-name = "SD_VCC"; + regulator-min-microvolt = <3000000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + regulator-boot-on; + }; + }; + }; }; &i2c1 { -- 2.30.2
