Qualcomm SAW Regulators
SAW (Subsystem Power Manager and Adaptive Voltage Scaling Wrapper) is a hardware
block in the Qualcomm chipsets that regulates the power to the CPU cores on devices
such as APQ8064, MSM8974, APQ8084 and others.
- compatible:
Usage: required
Value type: <string>
Definition: must be one of:
"qcom,apq8064-saw2-v1.1-regulator"
Example:
saw0: power-controller@2089000 {
compatible = "qcom,apq8064-saw2-v1.1-cpu", "qcom,saw2", "syscon", "simple-mfd";
reg = <0x02089000 0x1000>, <0x02009000 0x1000>;
#address-cells = <1>;
#size-cells = <1>;
saw0_regulator: regulator@2089000 {
compatible = "qcom,apq8064-saw2-v1.1-regulator";
