regulator: anatop: patching to device-tree property "reg".
Change "reg" to "anatop-reg-offset" due to there is a warning of handling no size field in reg. This patch also adds the missing device-tree binding documentation.

Anatop Voltage regulators
|
||||||
|
|
||||||
|
Required properties:
|
||||||
|
- compatible: Must be "fsl,anatop-regulator"
|
||||||
|
- anatop-reg-offset: Anatop MFD register offset
|
||||||
|
- anatop-vol-bit-shift: Bit shift for the register
|
||||||
|
- anatop-vol-bit-width: Number of bits used in the register
|
||||||
|
- anatop-min-bit-val: Minimum value of this register
|
||||||
|
- anatop-min-voltage: Minimum voltage of this regulator
|
||||||
|
- anatop-max-voltage: Maximum voltage of this regulator
|
||||||
|
|
||||||
|
Any property defined as part of the core regulator
|
||||||
|
binding, defined in regulator.txt, can also be used.

Example:
|
||||||
|
|
||||||
|
regulator-vddpu {
|
||||||
|
compatible = "fsl,anatop-regulator";
|
||||||
|
regulator-name = "vddpu";

||||||

regulator-min-microvolt = <725000>;
|
||||||
|
regulator-max-microvolt = <1300000>;
|
||||||
|
regulator-always-on;
|
||||||
|
anatop-reg-offset = <0x140>;
|
||||||
|
anatop-vol-bit-shift = <9>;
|
||||||
|
anatop-vol-bit-width = <5>;
|
||||||
|
anatop-min-bit-val = <1>;

||||||
|
anatop-min-voltage = <725000>;
|
||||||

anatop-max-voltage = <1300000>;
