I assume the board is this one: https://world.taobao.com/item/530374411673.htm > Signed-off-by: Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxx> > --- > arch/arm/boot/dts/Makefile | 1 + > arch/arm/boot/dts/sun8i-r16-parrot.dts | 333 +++++++++++++++++++++++++++++++++ > 2 files changed, 334 insertions(+) > create mode 100644 arch/arm/boot/dts/sun8i-r16-parrot.dts > > diff --git a/arch/arm/boot/dts/Makefile b/arch/arm/boot/dts/Makefile > index 06b6c2d..1149512 100644 > --- a/arch/arm/boot/dts/Makefile > +++ b/arch/arm/boot/dts/Makefile > @@ -760,6 +760,7 @@ dtb-$(CONFIG_MACH_SUN8I) += \ > sun8i-a33-ippo-q8h-v1.2.dtb \ > sun8i-a33-q8-tablet.dtb \ > sun8i-a33-sinlinx-sina33.dtb \ > + sun8i-r16-parrot.dtb \ > sun8i-a83t-allwinner-h8homlet-v2.dtb \ > sun8i-a83t-cubietruck-plus.dtb \ > sun8i-h3-orangepi-2.dtb \ > diff --git a/arch/arm/boot/dts/sun8i-r16-parrot.dts b/arch/arm/boot/dts/sun8i-r16-parrot.dts > new file mode 100644 > index 0000000..75e2420 > --- /dev/null > +++ b/arch/arm/boot/dts/sun8i-r16-parrot.dts > @@ -0,0 +1,333 @@ > +/* > + * Copyright 2015 Quentin Schulz > + * > + * Quentin Schulz <quentin.schulz@xxxxxxxxxxxxxxxxxx> > + * > + * This file is dual-licensed: you can use it either under the terms > + * of the GPL or the X11 license, at your option.

You may want to add parrot_ or parrot_evb_ to it.

Would turning it off render the system inoperable? How was it referenced in the fex file? If this is for WiFi I/O VCC, then you should specify it in mmc1 with vqmmc-supply. > +}; > + > +®_aldo2 { > + regulator-always-on; > + regulator-min-microvolt = <2350000>; > + regulator-max-microvolt = <2650000>; > + regulator-name = "vdd-dll"; > +}; > + > +®_aldo3 { > + regulator-always-on; > + regulator-min-microvolt = <2700000>; > + regulator-max-microvolt = <3300000>; > + regulator-name = "vcc-pll-avcc"; > +}; > + > +®_dc5ldo { > + regulator-always-on; > + regulator-min-microvolt = <900000>; > + regulator-max-microvolt = <1400000>; > + regulator-name = "vdd-cpus"; > +}; > + > +®_dcdc1 { > + regulator-always-on; > + regulator-min-microvolt = <3000000>; > + regulator-max-microvolt = <3000000>; > + regulator-name = "vcc-3v0"; > +}; > + > +®_dcdc2 { > + regulator-always-on; > + regulator-min-microvolt = <900000>; > + regulator-max-microvolt = <1400000>; > + regulator-name = "vdd-sys"; > +}; > + > +®_dcdc3 { > + regulator-always-on; > + regulator-min-microvolt = <900000>; > + regulator-max-microvolt = <1400000>; > + regulator-name = "vdd-cpu"; > +}; > + > +®_dcdc5 { > + regulator-always-on; > + regulator-min-microvolt = <1500000>; > + regulator-max-microvolt = <1500000>; > + regulator-name = "vcc-dram"; > +}; > + > +®_dldo1 { > + regulator-always-on; A comment saying why this is always on would be nice.
