Przemyslaw Marczak 52a3de5e12 dm: pmic: add max77686 pmic driver
This is the implementation of driver model PMIC driver.
The max77686 PMIC driver implements read/write operations and driver
bind method - to bind its childs.

This driver will try to bind the regulator devices by using it's child
info array with regulator prefixes and driver names. This should succeed
when compatible regulator driver is compiled. If no regulator driver found,
then the pmic can still provide read/write operations, and can be used with
PMIC function calls.

MAXIM, MAX77686 pmic
This device uses two drivers:
- drivers/power/pmic/max77686.c (for parent device)
- drivers/power/regulator/max77686.c (for child regulators)
This file describes the binding info for the PMIC driver.
To bind the regulators, please read the additional binding info:
- doc/device-tree-bindings/regulator/max77686.txt
Required properties:
- compatible: "maxim,max77686"
- reg = 0x9
With those two properties, the pmic device can be used for read/write only.
To bind each regulator, the optional regulators subnode should exists.
Optional subnode:
- voltage-regulators: subnode list of each device's regulator
(see max77686.txt - regulator binding info)
Example:
max77686@09 {
compatible = "maxim,max77686";
reg = <0x09>;
voltage-regulators {
ldo1 {
...
};
...
};
};
