[PATCH v4] ARM: dts: sun8i: Add dts file for Olimex A33-OLinuXino

From: Stefan Mavrodiev <hidden>
Date: 2016-07-25 12:37:44 

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

Changes for v4:
	- Green led renamed
	- Added OTG support

The "regulator" dc1sw is, in fact, a switch (so it's named as "sw").
So it have only on-off status.

The constraints in dc1sw has prevented one of my A31s tablet from booting
when it's not removed.

Then it's poorly named, and you should tie it to the MMC, and remove
the always-on if it's only used by the mmc. always-on is supposed to
be for regulators that shouldn't but turned off for the system to stay
running. Some MMC regulator doesn't fit that description.

If I remove "always-on" the board still will work, since dcdc1 is tied to 
mmc0. 
vmmc-supply = <&reg_dcdc1>;

We assume this voltage will be always present and there are some pullups that 
are tied to it (on i2c0 and i2c1 bus).  In this case should I remove "always-
on" from the regulator node?

It's named upon the A33 power pin - "VCC-DSI".
Usually, it's based on the name of the output in the schematics,
precisely because, from one board to another, it might have different
usage.

If I remove "always-on" the board still will work, since dcdc1 is tied to 
mmc0. 
vmmc-supply = <&reg_dcdc1>;

No, you should just tie that regulator to the i2c buses as well.
