pwm regulator bindings
|
|
|
|
Required properties:
|
|
- compatible: Should be "pwm-regulator"
|
|
- pwms: OF device-tree PWM specification (see PWM binding pwm.txt)
|
|
- voltage-table: voltage and duty table, include 2 members in each set of
|
|
brackets, first one is voltage(unit: uv), the next is duty(unit: percent)
|
|
|
|
Any property defined as part of the core regulator binding defined in
|
|
regulator.txt can also be used.
|
|
|
|
Example:
|
|
pwm_regulator {
|
|
compatible = "pwm-regulator;
|
|
pwms = <&pwm1 0 8448 0>;
|
|
|
|
voltage-table = <1114000 0>,
|
|
<1095000 10>,
|
|
<1076000 20>,
|
|
<1056000 30>,
|
|
<1036000 40>,
|
|
<1016000 50>;
|
|
|
|
regulator-min-microvolt = <1016000>;
|
|
regulator-max-microvolt = <1114000>;
|
|
regulator-name = "vdd_logic";
|
|
};
