ANATOP REGULATOR
Anatop is an integrated regulator inside i.MX6 SoC.
Required properties:
- compatible: Must be "fsl,anatop-regulator".
- regulator-name: Name of the regulator
- anatop-reg-offset: u32 value representing the anatop MFD register offset.
- anatop-vol-bit-shift: u32 value representing the bit shift for the register.
- anatop-vol-bit-width: u32 value representing the number of bits used in the
register.
- anatop-min-bit-val: u32 value representing the minimum value of this
register.
- anatop-min-voltage: u32 value representing the minimum voltage of this
regulator.
- anatop-max-voltage: u32 value representing the maximum voltage of this
regulator.
Optional properties:
- anatop-delay-reg-offset: u32 value representing the anatop MFD step time
register offset.
- anatop-delay-bit-shift: u32 value representing the bit shift for the step
time register.
- anatop-delay-bit-width: u32 value representing the number of bits used in
the step time register.
- anatop-enable-bit: u32 value representing regulator enable bit offset.
- vin-supply: input supply phandle.
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-delay-reg-offset = <0x170>;
anatop-delay-bit-shift = <24>;
anatop-delay-bit-width = <2>;
anatop-min-bit-val = <1>;
anatop-min-voltage = <725000>;
anatop-max-voltage = <1300000>;
};
