TPS65910 Power Management Integrated Circuit Required properties: - compatible: "ti,tps65910" or "ti,tps65911" - reg: I2C slave address - interrupts: the interrupt outputs of the controller - #gpio-cells: number of cells to describe a GPIO, this should be 2. The first cell is the GPIO number. The second cell is used to specify additional options . - gpio-controller: mark the device as a GPIO controller - #interrupt-cells: the number of cells to describe an IRQ, this should be 2. The first cell is the IRQ number. The second cell is the flags, encoded as the trigger masks from Documentation/devicetree/bindings/interrupt-controller/interrupts.txt - regulators: This is the list of child nodes that specify the regulator initialization data for defined regulators. Not all regulators for the given device need to be present. The definition for each of these nodes is defined using the standard binding for regulators found at Documentation/devicetree/bindings/regulator/regulator.txt. The regulator is matched with the regulator-compatible. The valid regulator-compatible values are: tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1, vaux2, vaux33, vmmc, vbb tps65911: vrtc, vio, vdd1, vdd3, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5, ldo6, ldo7, ldo8 - xxx-supply: Input voltage supply regulator. These entries are require if regulators are enabled for a device. Missing of these properties can cause the regulator registration fails. If some of input supply is powered through battery or always-on supply then also it is require to have these parameters with proper node handle of always on power supply. tps65910: vcc1-supply: VDD1 input. vcc2-supply: VDD2 input. vcc3-supply: VAUX33 and VMMC input. vcc4-supply: VAUX1 and VAUX2 input. vcc5-supply: VPLL and VDAC input. vcc6-supply: VDIG1 and VDIG2 input. vcc7-supply: VRTC and VBB input. vccio-supply: VIO input. tps65911: vcc1-supply: VDD1 input. vcc2-supply: VDD2 input. vcc3-supply: LDO6, LDO7 and LDO8 input. vcc4-supply: LDO5 input. vcc5-supply: LDO3 and LDO4 input. vcc6-supply: LDO1 and LDO2 input. vcc7-supply: VRTC input. vccio-supply: VIO input. Optional properties: - ti,vmbch-threshold: (tps65911) main battery charged threshold comparator. (see VMBCH_VSEL in TPS65910 datasheet) - ti,vmbch2-threshold: (tps65911) main battery discharged threshold comparator. (see VMBCH_VSEL in TPS65910 datasheet) - ti,en-ck32k-xtal: enable external 32-kHz crystal oscillator (see CK32K_CTRL in TPS6591X datasheet) - ti,en-gpio-sleep: enable sleep control for gpios There should be 9 entries here, one for each gpio. - ti,system-power-controller: Telling whether or not this pmic is controlling the system power. Regulator Optional properties: - ti,regulator-ext-sleep-control: enable external sleep control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)] If this property is not defined, it defaults to 0 (not enabled).
