[PATCH] [V2] ARM: dts: sun7i: Add dts file for Bananapi M1 Plus board

[luoyi.ly]

From: Luo Yi <luoyi.ly@gmail.com>

Add support for the Bananapi M1 Plus A20 development board from
sinovoip.com.cn . This board is nearly a clone of the Lemaker's
Bananapro, but differ with the wlan chipset connection and i2s pinout.
And I also enable the integrated audio codec on default.

Does anyone know if this should be enabled on the bananapro too?

Yes, everything that is shared with the banana-pro (which, judging
from Bernhard, is pretty much everything but a GPIO) should be merged
in the banapro DT.

Don't take my word for granted, as I do not own this hardware or know it
particularly well. There is no doubt that "BPi-M1+" and "Banana Pro" are
very similar, but if in doubt the information form the wiki should be 
verified.

@luoyi:

You seem to be using an editor that uses 4 spaces for displaying a <TAB>.
It looks like that makes you prone to whitespace formatting issues, which
have shown up in both versions of the .dts you submitted so far.

Please double-check that you're using TABs for indentation and they weren't
mixed up with SPACEs accidentally. (Most editors will also offer a setting
that allows you to display "non-printable" chars, where you might be able to
distinguish whitespace better.)

Hmmmm, ok. Chen-Yu, any input on this? You know the banana-pis much
more than I do.

I did a comparison of the "Banana Pro" vs the "BPi-M1+".

The differences are similar to what we have with any other development
board, say the Cubietruck:

  - A different WiFi chip is used, and the BT part is not hooked up.
  - Different GPIOs for external power regulator/switches
  - Different GPIOs for LEDs
  - Different peripherals exposed on the headers.

IMO There's no need to merge or have a common .dtsi for the two boards.
They (and all the other development boards) look similar because
everyone is following the basic set by Allwinner's reference design,
like which MMC controller and pins are used for SD/MMC, which ones
are used for SDIO-based WiFi, and so on.

I did a version completely from scratch using just the schematics:

  https://github.com/wens/linux/commits/bpi-m1-plus

Please ignore the last commit. It's just me playing with NTP support
for GPS time.

So, what do you mean by that? Do you have some comments on that patch,
or should I merge it, and you'll post your additions on top of it?
