1TPS65910 Power Management Integrated Circuit 2 3Required properties: 4- compatible: "ti,tps65910" or "ti,tps65911" 5- reg: I2C slave address 6- interrupts: the interrupt outputs of the controller 7- #gpio-cells: number of cells to describe a GPIO, this should be 2. 8 The first cell is the GPIO number. 9 The second cell is used to specify additional options <unused>. 10- gpio-controller: mark the device as a GPIO controller 11- #interrupt-cells: the number of cells to describe an IRQ, this should be 2. 12 The first cell is the IRQ number. 13 The second cell is the flags, encoded as the trigger masks from 14 Documentation/devicetree/bindings/interrupts.txt 15- regulators: This is the list of child nodes that specify the regulator 16 initialization data for defined regulators. Not all regulators for the given 17 device need to be present. The definition for each of these nodes is defined 18 using the standard binding for regulators found at 19 Documentation/devicetree/bindings/regulator/regulator.txt. 20 The regulator is matched with the regulator-compatible. 21 22 The valid regulator-compatible values are: 23 tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1, 24 vaux2, vaux33, vmmc 25 tps65911: vrtc, vio, vdd1, vdd3, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5, 26 ldo6, ldo7, ldo8 27 28- xxx-supply: Input voltage supply regulator. 29 These entries are require if regulators are enabled for a device. Missing of these 30 properties can cause the regulator registration fails. 31 If some of input supply is powered through battery or always-on supply then 32 also it is require to have these parameters with proper node handle of always 33 on power supply. 34 tps65910: 35 vcc1-supply: VDD1 input. 36 vcc2-supply: VDD2 input. 37 vcc3-supply: VAUX33 and VMMC input. 38 vcc4-supply: VAUX1 and VAUX2 input. 39 vcc5-supply: VPLL and VDAC input. 40 vcc6-supply: VDIG1 and VDIG2 input. 41 vcc7-supply: VRTC input. 42 vccio-supply: VIO input. 43 tps65911: 44 vcc1-supply: VDD1 input. 45 vcc2-supply: VDD2 input. 46 vcc3-supply: LDO6, LDO7 and LDO8 input. 47 vcc4-supply: LDO5 input. 48 vcc5-supply: LDO3 and LDO4 input. 49 vcc6-supply: LDO1 and LDO2 input. 50 vcc7-supply: VRTC input. 51 vccio-supply: VIO input. 52 53Optional properties: 54- ti,vmbch-threshold: (tps65911) main battery charged threshold 55 comparator.
