1 AXP family PMIC device tree bindings
3 The axp20x family current members :
13 - compatible: should be one of:
22 - reg: The I2C slave address or RSB hardware address for the AXP chip
23 - interrupt-parent: The parent interrupt controller
24 - interrupts: SoC NMI / GPIO interrupt connected to the PMIC's IRQ pin
25 - interrupt-controller: The PMIC has its own internal IRQs
26 - #interrupt-cells: Should be set to 1
29 - x-powers,dcdc-freq: defines the work frequency of DC-DC in KHz
30 AXP152/20X: range: 750-1875, Default: 1.5 MHz
31 AXP22X/80X: range: 1800-4050, Default: 3 MHz
33 - x-powers,drive-vbus-en: axp221 / axp223 only boolean, set this when the
34 N_VBUSEN pin is used as an output pin to control an external
35 regulator to drive the OTG VBus, rather then as an input pin
36 which signals whether the board is driving OTG VBus or not.
38 - x-powers,master-mode: Boolean (axp806 only). Set this when the PMIC is
39 wired for master mode. The default is slave mode.
41 - <input>-supply: a phandle to the regulator supply node. May be omitted if
42 inputs are unregulated, such as using the IPSOUT output
45 - regulators: A node that houses a sub-node for each regulator. Regulators
46 not used but preferred to be managed by the OS should be
48 See Documentation/devicetree/bindings/regulator/regulator.txt
49 for more information on standard regulator bindings.
51 Optional properties for DCDC regulators:
52 - x-powers,dcdc-workmode: 1 for PWM mode, 0 for AUTO (PWM/PFM) mode
53 Default: Current hardware setting
54 The DCDC regulators work in a mixed PWM/PFM mode,
55 using PFM under light loads and switching to PWM
56 for heavier loads. Forcing PWM mode trades efficiency
57 under light loads for lower output noise. This
58 probably makes sense for HiFi audio related
59 applications that aren't battery constrained.
