Subject: [PATCH 4/5] arm64: dts: allwinner: add support for Pinebook
|
|
|
|
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 RGB-eDP bridge.
|
|
- A mini HDMI port.
|
|
|
|
Misc:
|
|
- A Hall sensor designed to detect the status of lid, connected to GPIO PL12.
|
|
- A headphone jack connected to the SoC's internal codec.
|
|
- A debug UART port muxed with headphone jack.
|
|
|
|
This commit adds basical support for it.
|
|
|
|
[vasily: squashed several commits into one, added simplefb node, added usbphy
|
|
to ehci0 and ohci0 nodes and other cosmetic changes to dts]
