Signed-off-by: Timo Sigurdsson --- Changes since v1 (RFC): - Dropped the changes to the cpufreq operating points and renamed the patch accordingly - Limited the CPU voltage range so it doesn't exceed the SOC specifications --- arch/arm/boot/dts/sun7i-a20-bananapi.dts | 35 ++++++++++++++++++++++++++++---- 1 file changed, 31 insertions(+), 4 deletions(-) diff --git a/arch/arm/boot/dts/sun7i-a20-bananapi.dts b/arch/arm/boot/dts/sun7i-a20-bananapi.dts index 9f7b472..74382f3 100644 --- a/arch/arm/boot/dts/sun7i-a20-bananapi.dts +++ b/arch/arm/boot/dts/sun7i-a20-bananapi.dts @@ -92,6 +92,10 @@ status = "okay"; }; +&cpu0 { + cpu-supply = <®_dcdc2>; +}; + &ehci0 { status = "okay"; }; @@ -119,13 +123,9 @@ status = "okay"; axp209: pmic@34 { - compatible = "x-powers,axp209"; reg = <0x34>; interrupt-parent = <&nmi_intc>; interrupts = <0 IRQ_TYPE_LEVEL_LOW>; - - interrupt-controller; - #interrupt-cells = <1>; }; }; @@ -182,6 +182,33 @@ }; }; +#include "axp209.dtsi" + +®_dcdc2 { + regulator-always-on; + regulator-min-microvolt = <1000000>; + regulator-max-microvolt = <1400000>; + regulator-name = "vdd-cpu"; +}; + +®_dcdc3 { + regulator-always-on; + regulator-min-microvolt = <1000000>; + regulator-max-microvolt = <1400000>; + regulator-name = "vdd-int-dll"; +}; + +®_ldo1 { + regulator-name = "vdd-rtc"; +}; + +®_ldo2 { + regulator-always-on; + regulator-min-microvolt = <3000000>; + regulator-max-microvolt = <3000000>; + regulator-name = "avcc"; +}; + ®_usb1_vbus { status = "okay"; }; -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
