The Palma driver support this device. Enable following submodule of the TPS65913: - GPIO driver - RTC driver. - Power regulator driver. Signed-off-by: Laxman Dewangan --- Changes from V1: - renames nodes from palams_* to simple as gpio, rtc, pmic etc. - Added line gap properly. - Remove comment for palams-gpio reference as the entry itself explain. - Remove unit address for tps65913. Changes from V2: - Made LDO9 as always ON for sd card functionality. Hi Stephen, I observed that if sd card is not initailised in bootloader then it will not get enumerated in the kernel also. In my case, I am using fastboot and hence it is not observed that sd card is getting initialised. But today I use the uboot and on this, sd card is getting enumerated. And observer that LDO9 is getting disabled in late init call due to full constraint and it can create issue for sd card. With this modified patch I make the LDO9 as always ON. I am not able to validate this througly as the kernel crash in the method of uboot. Need more debugging. arch/arm/boot/dts/tegra114-dalmore.dts | 186 +++++++++++++++++++++++++++++++- 1 files changed, 185 insertions(+), 1 deletions(-) diff --git a/arch/arm/boot/dts/tegra114-dalmore.dts b/arch/arm/boot/dts/tegra114-dalmore.dts index a42bfa4..d5728ff 100644 --- a/arch/arm/boot/dts/tegra114-dalmore.dts +++ b/arch/arm/boot/dts/tegra114-dalmore.dts @@ -791,7 +791,7 @@ regulator-boot-on; }; - dcdc3 { + tps65090_dcdc3_reg: dcdc3 { regulator-name = "vdd-ao"; regulator-always-on; regulator-boot-on; @@ -836,6 +836,180 @@ }; }; }; + + palmas: tps65913 { + compatible = "ti,palmas"; + reg = <0x58>; + interrupts = <0 86 0x4>; + + #interrupt-cells = <2>; + interrupt-controller; + + palmas_gpio: gpio { + compatible = "ti,palmas-gpio"; + gpio-controller; + #gpio-cells = <2>; + }; + + rtc { + compatible = "ti,palmas-rtc"; + interrupt-parent = <&palmas>; + interrupts = <8 0>; + }; + + pmic { + compatible = "ti,tps65913-pmic", "ti,palmas-pmic"; + smps1-in-supply = <&tps65090_dcdc3_reg>; + smps3-in-supply = <&tps65090_dcdc3_reg>; + smps4-in-supply = <&tps65090_dcdc2_reg>; + smps7-in-supply = <&tps65090_dcdc2_reg>; + smps8-in-supply = <&tps65090_dcdc2_reg>; + smps9-in-supply = <&tps65090_dcdc2_reg>; + ldo1-in-supply = <&tps65090_dcdc2_reg>; + ldo2-in-supply = <&tps65090_dcdc2_reg>; + ldo3-in-supply = <&palmas_smps3_reg>; + ldo4-in-supply = <&tps65090_dcdc2_reg>; + ldo5-in-supply = <&vdd_ac_bat_reg>; + ldo6-in-supply = <&tps65090_dcdc2_reg>; + ldo7-in-supply = <&tps65090_dcdc2_reg>; + ldo8-in-supply = <&tps65090_dcdc3_reg>; + ldo9-in-supply = <&palmas_smps9_reg>; + ldoln-in-supply = <&tps65090_dcdc1_reg>; + ldousb-in-supply = <&tps65090_dcdc1_reg>; + + regulators { + smps12 { + regulator-name = "vddio-ddr"; + regulator-min-microvolt = <1350000>; + regulator-max-microvolt = <1350000>; + regulator-always-on; + regulator-boot-on; + }; + + palmas_smps3_reg: smps3 { + regulator-name = "vddio-1v8"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + regulator-always-on; + regulator-boot-on; + }; + + smps45 { + regulator-name = "vdd-core"; + regulator-min-microvolt = <900000>; + regulator-max-microvolt = <1400000>; + regulator-always-on; + regulator-boot-on; + }; + + smps457 { + regulator-name = "vdd-core"; + regulator-min-microvolt = <900000>; + regulator-max-microvolt = <1400000>; + regulator-always-on; + regulator-boot-on; + }; + + smps8 { + regulator-name = "avdd-pll"; + regulator-min-microvolt = <1050000>; + regulator-max-microvolt = <1050000>; + regulator-always-on; + regulator-boot-on; + }; + + palmas_smps9_reg: smps9 { + regulator-name = "sdhci-vdd-sd-slot"; + regulator-min-microvolt = <2800000>; + regulator-max-microvolt = <2800000>; + regulator-always-on; + }; + + ldo1 { + regulator-name = "avdd-cam1"; + regulator-min-microvolt = <2800000>; + regulator-max-microvolt = <2800000>; + }; + + ldo2 { + regulator-name = "avdd-cam2"; + regulator-min-microvolt = <2800000>; + regulator-max-microvolt = <2800000>; + }; + + ldo3 { + regulator-name = "avdd-dsi-csi"; + regulator-min-microvolt = <1200000>; + regulator-max-microvolt = <1200000>; + regulator-always-on; + regulator-boot-on; + }; + + ldo4 { + regulator-name = "vpp-fuse"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + }; + + ldo6 { + regulator-name = "vdd-sensor-2v85"; + regulator-min-microvolt = <2850000>; + regulator-max-microvolt = <2850000>; + }; + + ldo7 { + regulator-name = "vdd-af-cam1"; + regulator-min-microvolt = <2800000>; + regulator-max-microvolt = <2800000>; + }; + + ldo8 { + regulator-name = "vdd-rtc"; + regulator-min-microvolt = <900000>; + regulator-max-microvolt = <900000>; + regulator-always-on; + regulator-boot-on; + ti,enable-ldo8-tracking; + }; + + ldo9 { + regulator-name = "vddio-sdmmc-2"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + regulator-boot-on; + }; + + ldoln { + regulator-name = "hvdd-usb"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + }; + + ldousb { + regulator-name = "avdd-usb"; + regulator-min-microvolt = <3300000>; + regulator-max-microvolt = <3300000>; + regulator-always-on; + regulator-boot-on; + }; + + regen1 { + regulator-name = "rail-3v3"; + regulator-max-microvolt = <3300000>; + regulator-always-on; + regulator-boot-on; + }; + + regen2 { + regulator-name = "rail-5v0"; + regulator-max-microvolt = <5000000>; + regulator-always-on; + regulator-boot-on; + }; + }; + }; + }; }; spi@7000da00 { @@ -980,6 +1154,16 @@ gpio = <&gpio TEGRA_GPIO(K, 1) GPIO_ACTIVE_HIGH>; vin-supply = <&tps65090_dcdc1_reg>; }; + + vdd_cam_1v8_reg: regulator@6 { + compatible = "regulator-fixed"; + reg = <6>; + regulator-name = "vdd_cam_1v8_reg"; + regulator-min-microvolt = <1800000>; + regulator-max-microvolt = <1800000>; + enable-active-high; + gpio = <&palmas_gpio 6 0>; + }; }; sound { -- 1.7.1.1
