Subject: dm: regulator: add max77686 regulator driver
This commit adds support to MAX77686 regulator driver,
based on a driver model regulator's API. It implements
almost all regulator operations, beside those for setting
and geting the Current value.
For proper bind and operation it requires the MAX77686 PMIC driver.
New file: drivers/power/regulator/max77686.c
New config: CONFIG_DM_REGULATOR_MAX77686

+MAXIM, MAX77686 regulators
+
+This device uses two drivers:
+- drivers/power/pmic/max77686.c (as parent I/O device)
+- drivers/power/regulator/max77686.c (for child regulators)
+
+This file describes the binding info for the REGULATOR driver.
+
+First, please read the binding info for the pmic:
+- doc/device-tree-bindings/pmic/max77686.txt
+
+Required subnode:
+- voltage-regulators: required for the PMIC driver
+
+Required properties:
+- regulator-name: used for regulator uclass platform data '.name'
+
+Optional:
+- regulator-min-microvolt: minimum allowed Voltage to set
+- regulator-max-microvolt: minimum allowed Voltage to set
+- regulator-always-on: regulator should be never disabled
+- regulator-boot-on: regulator should be enabled by the bootloader
+
+Example:
+(subnode of max77686 pmic node)
+voltage-regulators {
+ ldo1 {
+ regulator-name = "VDD_ALIVE_1.0V";
+ regulator-min-microvolt = <1000000>;
+ regulator-max-microvolt = <1000000>;
+ regulator-always-on;
+ regulator-boot-on;
+ };
+
+ ldo2 {
+ regulator-name = "VDDQ_VM1M2_1.2V";
+ regulator-min-microvolt = <1200000>;
+ regulator-max-microvolt = <1200000>;
+ regulator-always-on;
+ regulator-boot-on;
+ };
+ .
+ .
+ .
+ ldo26 {
+ regulator-name = "nc";
+ regulator-min-microvolt = <3000000>;
+ regulator-max-microvolt = <3000000>;
