The cvdd regulator is fixed at 1.2V on this board so disable the lower operating points and enable the 375MHz opp. Signed-off-by: Bartosz Golaszewski --- arch/arm/boot/dts/da850-evm.dts | 30 ++++++++++++++++++++++++++++++ 1 file changed, 30 insertions(+) diff --git a/arch/arm/boot/dts/da850-evm.dts b/arch/arm/boot/dts/da850-evm.dts index f04bc3e15332..f63867692da4 100644 --- a/arch/arm/boot/dts/da850-evm.dts +++ b/arch/arm/boot/dts/da850-evm.dts @@ -151,6 +151,15 @@ system-clock-frequency = <24576000>; }; }; + + cvdd: regulator0 { + compatible = "regulator-fixed"; + regulator-name = "cvdd"; + regulator-min-microvolt = <1200000>; + regulator-max-microvolt = <1200000>; + regulator-always-on; + regulator-boot-on; + }; }; &ecap2 { @@ -191,6 +200,27 @@ }; }; +&cpu { + cpu-supply = <&cvdd>; +}; + +/* + * DA850-EVM has a fixed CVDD of 1.2V - we cannot go below 300MHz or + * above 375MHz. + */ + +&opp_100 { + status = "disabled"; +}; + +&opp_200 { + status = "disabled"; +}; + +&opp_375 { + status = "okay"; +}; + &sata { status = "okay"; }; -- 2.20.1
