-AS3711 is an I2C PMIC from Austria MicroSystems with multiple DCDC and LDO power
-supplies, a battery charger and an RTC. So far only bindings for the two stepup
-DCDC converters are defined. Other DCDC and LDO supplies are configured, using
-standard regulator properties, they must belong to a sub-node, called
-"regulators" and be called "sd1" to "sd4" and "ldo1" to "ldo8." Stepup converter
-configuration should be placed in a subnode, called "backlight."
-
-Compulsory properties:
-- compatible : must be "ams,as3711"
-- reg : specifies the I2C address
-
-To use the SU1 converter as a backlight source the following two properties must
-be provided:
-- su1-dev : framebuffer phandle
-- su1-max-uA : maximum current
-
-To use the SU2 converter as a backlight source the following two properties must
-be provided:
-- su2-dev : framebuffer phandle
-- su1-max-uA : maximum current
-
-Additionally one of these properties must be provided to select the type of
-feedback used:
-- su2-feedback-voltage : voltage feedback is used
-- su2-feedback-curr1 : CURR1 input used for current feedback
-- su2-feedback-curr2 : CURR2 input used for current feedback
-- su2-feedback-curr3 : CURR3 input used for current feedback
-- su2-feedback-curr-auto: automatic current feedback selection
-
-and one of these to select the over-voltage protection pin
-- su2-fbprot-lx-sd4 : LX_SD4 is used for over-voltage protection
-- su2-fbprot-gpio2 : GPIO2 is used for over-voltage protection
-- su2-fbprot-gpio3 : GPIO3 is used for over-voltage protection
-- su2-fbprot-gpio4 : GPIO4 is used for over-voltage protection
-
-If "su2-feedback-curr-auto" is selected, one or more of the following properties
-have to be specified:
-- su2-auto-curr1 : use CURR1 input for current feedback
-- su2-auto-curr2 : use CURR2 input for current feedback
-- su2-auto-curr3 : use CURR3 input for current feedback
-
-Example:
-
-as3711@40 {
- compatible = "ams,as3711";
- reg = <0x40>;
-
- regulators {
- sd4 {
- regulator-name = "1.215V";
- regulator-min-microvolt = <1215000>;
- regulator-max-microvolt = <1235000>;
- };
- ldo2 {
- regulator-name = "2.8V CPU";
- regulator-min-microvolt = <2800000>;
- regulator-max-microvolt = <2800000>;
- regulator-always-on;
- regulator-boot-on;
- };
- };
-
- backlight {
- compatible = "ams,as3711-bl";
- su2-dev = <&lcdc>;
- su2-max-uA = <36000>;
- su2-feedback-curr-auto;
- su2-fbprot-gpio4;
