+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,axp809"
+    * "x-powers,axp813"
+- reg: The I2C slave address or RSB hardware address for the AXP chip
+- interrupts: SoC NMI / GPIO interrupt connected to the PMIC's IRQ pin
+- interrupt-controller: The PMIC 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
+		      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.
