[PATCH v3] ARM: dts: sun8i: Add dts file for Olimex A33-OLinuXino

[PATCH v3] ARM: dts: sun8i: Add dts file for Olimex A33-OLinuXino

[Stefan Mavrodiev]

A33-OLinuXino is A33 development board designed by Olimex LTD.

It has AXP233 PMU, 1GB DRAM, a micro SD card, one USB-OTG connector,
headphone and mic jacks, connector for LiPo battery and optional
4GB NAND Flash.

It has two 40-pin headers. One for LCD panel, and one for
additional modules. Also there is CSI/DSI connector.

Changes for v2:
	- Removed unused power nodes
	- Removed default-trigger for green led
	- Removed "always-on" option for LCD power

Changes for v3:
	- Nodes are sorted alphabetically

in that case.

The hardware should work as OTG. In FEL mode it works as device, and in current dt configuration - as host. I've spend some time trying to make it work as otg, but didn't succeed. 

There are some hardware differences between our board and other a33, but if you say that OTG work, I'll spend some additional time working on it.

There are some hardware differences between our board and other a33, but if you say that OTG work, I'll spend some additional time working on it.

Yes, I've been testing and got it to work on at least two other A33
boards (the R16 Parrot and the Sinlinx SinA33). You can look at the
Parrot DT, you should have everything you need (but you will most
likely need linux-next).
