AXP202/AXP209 device tree bindings
The axp20x family current members :
axp202 (X-Powers)
axp209 (X-Powers)
Required properties:
- compatible: "x-powers,axp202" or "x-powers,axp209"
- reg: The I2C slave address for the AXP chip
- interrupt-parent: The parent interrupt controller
- interrupts: SoC NMI / GPIO interrupt connected to the PMIC's IRQ pin
- interrupt-controller: axp20x has its own internal IRQs
- #interrupt-cells: Should be set to 1
Optional properties:
- x-powers,dcdc-freq: defines the work frequency of DC-DC in KHz
(range: 750-1875). Default: 1.5MHz
- <input>-supply: a phandle to the regulator supply node. May be omitted if
inputs are unregulated, such as using the IPSOUT output
from the PMIC.
- regulators: A node that houses a sub-node for each regulator. Regulators
not used but preferred to be managed by the OS should be
listed as well.
See Documentation/devicetree/bindings/regulator/regulator.txt
for more information on standard regulator bindings.
Optional properties for DCDC regulators:
- x-powers,dcdc-workmode: 1 for PWM mode, 0 for AUTO (PWM/PFM) mode
Default: Current hardware setting
The DCDC regulators work in a mixed PWM/PFM mode,
using PFM under light loads and switching to PWM
for heavier loads. Forcing PWM mode trades efficiency
under light loads for lower output noise. This
probably makes sense for HiFi audio related
applications that aren't battery constrained.
AXP202/AXP209 regulators, type, and corresponding input supply names:

select its own mode based on
realtime current draw, only for:
pm8921 smps and ftsmps
- qcom,power-mode-hysteretic:
Usage: optional
Value type: <empty>
Definition: select that the power supply should operate in hysteretic
mode, instead of the default pwm mode

- qcom,force-mode:
Usage: optional
Value type: <u32>
Defintion: indicates that the regulator should not be forced to any
particular mode, valid values are:
QCOM_RPM_FORCE_MODE_NONE - do not force any mode
QCOM_RPM_FORCE_MODE_LPM - force into low power mode
QCOM_RPM_FORCE_MODE_HPM - force into high power mode
QCOM_RPM_FORCE_MODE_BYPASS - set regulator to use bypass
mode, i.e. to act as a switch
and not regulate, only for:
pm8921 pldo, nldo and nldo1200
=== Negative Charge Pump custom properties
- qcom,switch-mode-frequency:
Usage: required
Value type: <u32>
Definition: Frequency (Hz) of the swith mode power supply;
must be one of:
