0001 TPS65910 Power Management Integrated Circuit
0002
0003 Required properties:
0004 - compatible: "ti,tps65910" or "ti,tps65911"
0005 - reg: I2C slave address
0006 - interrupts: the interrupt outputs of the controller
0007 - #gpio-cells: number of cells to describe a GPIO, this should be 2.
0008 The first cell is the GPIO number.
0009 The second cell is used to specify additional options <unused>.
0010 - gpio-controller: mark the device as a GPIO controller
0011 - #interrupt-cells: the number of cells to describe an IRQ, this should be 2.
0012 The first cell is the IRQ number.
0013 The second cell is the flags, encoded as the trigger masks from
0014 Documentation/devicetree/bindings/interrupt-controller/interrupts.txt
0015 - regulators: This is the list of child nodes that specify the regulator
0016 initialization data for defined regulators. Not all regulators for the given
0017 device need to be present. The definition for each of these nodes is defined
0018 using the standard binding for regulators found at
0019 Documentation/devicetree/bindings/regulator/regulator.txt.
0020 The regulator is matched with the regulator-compatible.
0021
0022 The valid regulator-compatible values are:
0023 tps65910: vrtc, vio, vdd1, vdd2, vdd3, vdig1, vdig2, vpll, vdac, vaux1,
0024 vaux2, vaux33, vmmc, vbb
0025 tps65911: vrtc, vio, vdd1, vdd2, vddctrl, ldo1, ldo2, ldo3, ldo4, ldo5,
0026 ldo6, ldo7, ldo8
0027
0028 - xxx-supply: Input voltage supply regulator.
0029 These entries are required if regulators are enabled for a device. Missing these
0030 properties can cause the regulator registration to fail.
0031 If some of input supply is powered through battery or always-on supply then
0032 also it is require to have these parameters with proper node handle of always
0033 on power supply.
0034 tps65910:
0035 vcc1-supply: VDD1 input.
0036 vcc2-supply: VDD2 input.
0037 vcc3-supply: VAUX33 and VMMC input.
0038 vcc4-supply: VAUX1 and VAUX2 input.
0039 vcc5-supply: VPLL and VDAC input.
0040 vcc6-supply: VDIG1 and VDIG2 input.
0041 vcc7-supply: VRTC and VBB input.
0042 vccio-supply: VIO input.
0043 tps65911:
0044 vcc1-supply: VDD1 input.
0045 vcc2-supply: VDD2 input.
0046 vcc3-supply: LDO6, LDO7 and LDO8 input.
0047 vcc4-supply: LDO5 input.
0048 vcc5-supply: LDO3 and LDO4 input.
0049 vcc6-supply: LDO1 and LDO2 input.
0050 vcc7-supply: VRTC input.
0051 vccio-supply: VIO input.
0052
0053 Optional properties:
0054 - ti,vmbch-threshold: (tps65911) main battery charged threshold
0055 comparator. (see VMBCH_VSEL in TPS65910 datasheet)
0056 - ti,vmbch2-threshold: (tps65911) main battery discharged threshold
0057 comparator. (see VMBCH_VSEL in TPS65910 datasheet)
0058 - ti,en-ck32k-xtal: enable external 32-kHz crystal oscillator (see CK32K_CTRL
0059 in TPS6591X datasheet)
0060 - ti,en-gpio-sleep: enable sleep control for gpios
0061 There should be 9 entries here, one for each gpio.
0062 - ti,system-power-controller: Telling whether or not this pmic is controlling
0063 the system power.
0064 - ti,sleep-enable: Enable SLEEP state.
0065 - ti,sleep-keep-therm: Keep thermal monitoring on in sleep state.
0066 - ti,sleep-keep-ck32k: Keep the 32KHz clock output on in sleep state.
0067 - ti,sleep-keep-hsclk: Keep high speed internal clock on in sleep state.
0068
0069 Regulator Optional properties:
0070 - ti,regulator-ext-sleep-control: enable external sleep
0071 control through external inputs [0 (not enabled), 1 (EN1), 2 (EN2) or 4(EN3)]
0072 If this property is not defined, it defaults to 0 (not enabled).
