1 AS3711 is an I2C PMIC from Austria MicroSystems with multiple DCDC and LDO power
2 supplies, a battery charger and an RTC. So far only bindings for the two stepup
3 DCDC converters are defined. Other DCDC and LDO supplies are configured, using
4 standard regulator properties, they must belong to a sub-node, called
5 "regulators" and be called "sd1" to "sd4" and "ldo1" to "ldo8." Stepup converter
6 configuration should be placed in a subnode, called "backlight."
9 - compatible : must be "ams,as3711"
10 - reg : specifies the I2C address
12 To use the SU1 converter as a backlight source the following two properties must
14 - su1-dev : framebuffer phandle
15 - su1-max-uA : maximum current
17 To use the SU2 converter as a backlight source the following two properties must
19 - su2-dev : framebuffer phandle
20 - su1-max-uA : maximum current
22 Additionally one of these properties must be provided to select the type of
24 - su2-feedback-voltage : voltage feedback is used
25 - su2-feedback-curr1 : CURR1 input used for current feedback
26 - su2-feedback-curr2 : CURR2 input used for current feedback
27 - su2-feedback-curr3 : CURR3 input used for current feedback
28 - su2-feedback-curr-auto: automatic current feedback selection
30 and one of these to select the over-voltage protection pin
31 - su2-fbprot-lx-sd4 : LX_SD4 is used for over-voltage protection
32 - su2-fbprot-gpio2 : GPIO2 is used for over-voltage protection
33 - su2-fbprot-gpio3 : GPIO3 is used for over-voltage protection
34 - su2-fbprot-gpio4 : GPIO4 is used for over-voltage protection
36 If "su2-feedback-curr-auto" is selected, one or more of the following properties
38 - su2-auto-curr1 : use CURR1 input for current feedback
39 - su2-auto-curr2 : use CURR2 input for current feedback
40 - su2-auto-curr3 : use CURR3 input for current feedback
