1Voltage/Current regulator

3Binding:
4The regulator devices don't use the "compatible" property. The binding is done
5by the prefix of regulator node's name. Usually the pmic I/O driver will provide
6the array of 'struct pmic_child_info' with the prefixes and compatible drivers.
7The bind is done by calling function: pmic_bind_childs().
8Example drivers:
9pmic: drivers/power/pmic/max77686.c
10regulator: drivers/power/regulator/max77686.c
11
12For the node name e.g.: "prefix[:alpha:]num { ... }":
13- the driver prefix should be: "prefix" or "PREFIX" - case insensitive
14- the node name's "num" is set as "dev->driver_data" on bind
15
16Example the prefix "ldo" will pass for: "ldo1", "ldo@1", "LDO1", "LDOREG@1"...

18Required properties:
19- regulator-name: a string, required by the regulator uclass
20
21Note
22The "regulator-name" constraint is used for setting the device's uclass
23platform data '.name' field. And the regulator device name is set from
24it's node name.
25
26Optional properties:
27- regulator-min-microvolt: a minimum allowed Voltage value
28- regulator-max-microvolt: a maximum allowed Voltage value
29- regulator-min-microamp: a minimum allowed Current value
30- regulator-max-microamp: a maximum allowed Current value
31- regulator-always-on: regulator should never be disabled
32- regulator-boot-on: enabled by bootloader/firmware
33
34Other kernel-style properties, are currently not used.
35
36Note:
37For the regulator autoset from constraints, the framework expects that:
38- regulator-min-microvolt is equal to regulator-max-microvolt
39- regulator-min-microamp is equal to regulator-max-microamp
40- regulator-always-on or regulator-boot-on is set
41
42Example:
43ldo0 {
44	/* Mandatory */
45	regulator-name = "VDDQ_EMMC_1.8V";
46
47	/* Optional */
48	regulator-min-microvolt = <1800000>;
49	regulator-max-microvolt = <1800000>;
50	regulator-min-microamp = <100000>;
51	regulator-max-microamp = <100000>;
52	regulator-always-on;
53	regulator-boot-on;
54};
