As per the schematic Monolithic Power Systems MP2161GJ-C499 supply a fixed output voltage of 5.0V. This supplies linked to VDD_EE, HDMI_P5V0, USB_POWER, VCCK, VDDIO_AO1V8, DDR_VDDC according to the schematics.

Added regulator-always-on since this is core input regulator. Split the linking on regulator and usb node in separate patch. Later more patchs will follow linking more core regulator as per shematics. --- arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts | 9 +++++++++ 1 file changed, 9 insertions(+) diff --git a/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts b/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts index 9972b1515da6..41d5fa370eb3 100644 --- a/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts +++ b/arch/arm64/boot/dts/amlogic/meson-gxbb-odroidc2.dts @@ -50,6 +50,15 @@ }; }; + p5v0: regulator-p5v0 { + compatible = "regulator-fixed"; + + regulator-name = "P5V0"; + regulator-min-microvolt = <5000000>; + regulator-max-microvolt = <5000000>; + regulator-always-on; + }; + tflash_vdd: regulator-tflash_vdd { /* * signal name from schematics: TFLASH_VDD_EN -- 2.23.0
