Signed-off-by: Quentin Schulz --- Patch dependencies: - regulator: axp20x: Add support for the (external) drivebus regulator - ARM: dts: axp22x.dtsi: Add reg_drivebus node - ARM: dts: axp22x.dtsi: Add usb_power_supply node - power: axp20x_usb: Add support for usb power-supply on axp22x pmics - mfd: axp20x: Extend axp22x_volatile_ranges - mfd: axp20x: Add axp20x-usb-power-supply for axp22x pmics - phy-sun4i-usb: Add workaround for missing Vbus det interrupts on A31 or the micro USB port would not be powered. v2: - correct typos, - chose less generic name suffix for nodes (now_parrot_r16), - add comment for i2c childless node, - add comment for two regulators-powered WiFi chip, - add comment to explicit the use of some regulators, - add usb_vbus_power-supply property in usbphy node (this adds a dependance to an other patch), arch/arm/boot/dts/Makefile | 1 + arch/arm/boot/dts/sun8i-r16-parrot.dts | 356 +++++++++++++++++++++++++++++++++ 2 files changed, 357 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 1ff5434..6c7581f 100644 --- a/arch/arm/boot/dts/Makefile +++ b/arch/arm/boot/dts/Makefile @@ -762,6 +762,7 @@ 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..cd68bfa --- /dev/null +++ b/arch/arm/boot/dts/sun8i-r16-parrot.dts @@ -0,0 +1,356 @@ +/* + * Copyright 2016 Quentin Schulz + * + * Quentin Schulz + * + * This file is dual-licensed: you can use it either under the terms + * of the GPL or the X11 license, at your option.
