regulator: da9210: add Device Tree support
This patch adds basic Device Tree support to the da9210 regulator driver - with no special properties, since also driver's platform data only contains standard regulator initialisation parameters.

* Dialog Semiconductor DA9210 Voltage Regulator
|
||||
|
||||
Required properties:
|
||||
|
||||
- compatible: must be "diasemi,da9210"
|
||||
- reg: the i2c slave address of the regulator. It should be 0x68.
|
||||
|
||||
Any standard regulator properties can be used to configure the single da9210
|
||||
DCDC.
|
||||
|
||||
Example:
|
||||
|
||||
da9210@68 {
|
||||
compatible = "diasemi,da9210";
|
||||
reg = <0x68>;
|
||||
|
||||
regulator-min-microvolt = <900000>;
|
||||
regulator-max-microvolt = <1000000>;
|
||||
regulator-boot-on;
|
||||
regulator-always-on;
|
||||
};
