[PATCH 0/2] arm64: dts: allwinner: Add Orange Pi Zero 2W support

[Andre Przywara]

Hi,

this adds support for the Orange Pi Zero 2W, a small board in the
Raspberry Pi Zero form factor, but with an Allwinner H618 Soc and up to
4 GB of DRAM.

This is just for the base board, created by looking at the schematics.
There is an FPC connector, which connects to a stackable expansion
board, that provides two additional USB-A sockets and an Ethernet jack,
among other connectors.
What is the recommended way to model this, via a DT overlay, applied
dynamically by the bootloader, or using a separate .dts file, that
includes this base board file?

Cheers,
Andre

The Orange Pi Zero 2W is a small board with an Allwinner H618 SoC.

Add the compatible string to the binding documents.

[PATCH 2/2] arm64: dts: allwinner: h616: add Orange Pi Zero 2W support

[Andre Przywara]

The Orange Pi Zero 2W is a board based on the Allwinner H618 SoC.
It uses the RaspberryPi Zero form factor, with an optional expansion
board, connected via an FPC connector, to provide more connectors.

The base board features:
	- Allwinner H618 SoC (quad Cortex-A53 cores, with 1MB L2 cache)
	- 1, 2 or 4GB of LPDDR4 DRAM
	- SD card socket
	- two USB-C sockets, one UFP, one DFP
	- HDMI connector
	- (yet unsupported) WiFi module
	- 16 MiB SPI flash
	- power supply via the UFP USB-C port

The FPC connector provides access to two more USB host ports, Fast
Ethernet, some GPIOs, Audio Line out and the IR receiver pin.

I compared it to the schematic and all values looks good. Sadly, it missed 
merge window.

I would do it through DT overlay. It can be included in kernel, alongside
board DT.

No worries, I wasn't expecting it to make it, just wanted to get this
out to start the discussion and have something at a canonical place,
since the first boards seem to arrive for people now.
