[PATCH] arm64: dts: allwinner: add support for Pinebook

[Icenowy Zheng]

25.02.2017, 15:01, "Icenowy Zheng" <icenowy at aosc.xyz>:
> Pinebook is a A64-based laptop produced by Pine64, with the following
> peripherals:
>
> USB:
> - Two external USB ports (one is directly connected to A64's OTG
> controller, the other is under a internal hub connected to the host-only
> controller.)
> - USB HID keyboard and touchpad connected to the internal hub.
> - USB UVC camera connected to the internal hub.
>
> Power-related:
> - A DC IN jack connected to AXP803's DCIN pin.
> - A Li-Polymer battery connected to AXP803's battery pins.
>
> Storage:
> - An eMMC by Foresee on the main board (in the product revision of the
> main board it's designed to be switchable).
> - An external MicroSD card slot.
>
> Display:
> - An eDP LCD panel (1366x768) connected via an ANX6345/ANX9807 RGB-eDP
> bridge.
> - A mini HDMI jack.
>
> Misc:
> - A Hall sensor designed to detect the status of lid, connected to GPIO PH10.
> - A headphone jack connected to the SoC's internal codec.
> - A BMA223 gravity sensor connected to the SoC's I2C1 bus. (Not
> supported yet)
> - A debug UART port muxed with one of the USB ports, only available on
> product revision of the main board.
>
> This commit adds basical support for it, with out-of-tree patches for
> display support the laptop can be basically usable.

Sorry but I missed a line here:

#include <dt-bindings/input/input.h>

It's for the switch code for gpio_keys part (it's used to describe
the Hall sensor).
