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" - case sensitive
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", "ldoreg@1, ...
17
18Optional properties:
19- regulator-name: a string, required by the regulator uclass
20- regulator-min-microvolt: a minimum allowed Voltage value
21- regulator-max-microvolt: a maximum allowed Voltage value
22- regulator-min-microamp: a minimum allowed Current value
23- regulator-max-microamp: a maximum allowed Current value
24- regulator-always-on: regulator should never be disabled
25- regulator-boot-on: enabled by bootloader/firmware
26
27Note
28The "regulator-name" constraint is used for setting the device's uclass
29platform data '.name' field. And the regulator device name is set from
30it's node name. If "regulator-name" is not provided in dts, node name
31is chosen for setting the device's uclass platform data '.name' field.
32
33Other kernel-style properties, are currently not used.
34
35Note:
36For the regulator autoset from constraints, the framework expects that:
37- regulator-min-microvolt is equal to regulator-max-microvolt
38- regulator-min-microamp is equal to regulator-max-microamp
39- regulator-always-on or regulator-boot-on is set

41Example:
42ldo0 {
43	/* Optional */
44	regulator-name = "VDDQ_EMMC_1.8V";
45	regulator-min-microvolt = <1800000>;
46	regulator-max-microvolt = <1800000>;
47	regulator-min-microamp = <100000>;
48	regulator-max-microamp = <100000>;
49	regulator-always-on;
50	regulator-boot-on;
51};
