[PATCH v2] ARM: sun8i: Add Parrot Board DTS

From: Quentin Schulz
Date: Wed Jun 22 2016 - 09:42:33 EST

The Parrot Board is an evaluation board with an Allwinner R16 (assumed
to be close to an Allwinner A33), 4GB of eMMC, 512MB of RAM, USB host
and OTG, a WiFi/Bluetooth combo chip, a micro SD Card reader, 2
controllable buttons, an LVDS port with separated backlight and
capacitive touch panel ports, an audio/microphone jack, a camera CSI
port, 2 sets of 22 GPIOs and an accelerometer.

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),
