-AXP family PMIC device tree bindings
-
-The axp20x family current members :
-axp152 (X-Powers)
-axp202 (X-Powers)
-axp209 (X-Powers)
-axp221 (X-Powers)
-axp223 (X-Powers)
-axp803 (X-Powers)
-axp806 (X-Powers)
-axp809 (X-Powers)
-axp813 (X-Powers)
-
-The AXP813 is 2 chips packaged into 1. The 2 chips do not share anything
-other than the packaging. Pins are routed separately. As such they should
-be treated as separate entities. The other half is an AC100 RTC/codec
-combo chip. Please see ./ac100.txt for its bindings.
-
-Required properties:
-- compatible: should be one of:
- * "x-powers,axp152"
- * "x-powers,axp202"
- * "x-powers,axp209"
- * "x-powers,axp221"
- * "x-powers,axp223"
- * "x-powers,axp803"
- * "x-powers,axp806"
- * "x-powers,axp805", "x-powers,axp806"
- * "x-powers,axp305", "x-powers,axp805", "x-powers,axp806"
- * "x-powers,axp809"
- * "x-powers,axp813"
-- reg: The I2C slave address or RSB hardware address for the AXP chip
-- interrupt-controller: The PMIC has its own internal IRQs
-- #interrupt-cells: Should be set to 1
-
-Supported common regulator properties, see ../regulator/regulator.txt for
-more information:
-- regulator-ramp-delay: sets the ramp up delay in uV/us
- AXP20x/DCDC2: 1600, 800
- AXP20x/LDO3: 1600, 800
-- regulator-soft-start: enable the output at the lowest possible voltage and
- only then set the desired voltage
- AXP20x/LDO3: software-based implementation
-
-Optional properties:
-- interrupts: SoC NMI / GPIO interrupt connected to the PMIC's IRQ pin
-- x-powers,dcdc-freq: defines the work frequency of DC-DC in KHz
- AXP152/20X: range: 750-1875, Default: 1.5 MHz
- AXP22X/8XX: range: 1800-4050, Default: 3 MHz
-
-- x-powers,drive-vbus-en: boolean, set this when the N_VBUSEN pin is
- used as an output pin to control an external
- regulator to drive the OTG VBus, rather then
- as an input pin which signals whether the
- board is driving OTG VBus or not.
- (axp221 / axp223 / axp803/ axp813 only)
-
-- x-powers,self-working-mode and
- x-powers,master-mode: Boolean (axp806 only). Set either of these when the
- PMIC is wired for self-working mode or master mode.
- If neither is set then slave mode is assumed.
- This corresponds to how the MODESET pin is wired.
-
-- <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.
