board: add support for Banana Pro

Browse Source 
The board support package includes the following components:
 - U-Boot 2016.11
 - Linux 4.9.3
 - packages:
   - alsa-utils for basic audio usage of the on-board headphone jack
     and microphone
   - iw and wpa_supplicant for managing the wireless interface

Two Linux patches are necessary to enable audio and wifi support. Both
patches are fetched from the Linux next branch and are probably mainlined in
Linux 4.11.

A Linux configuration fragment enables the wireless device driver, which
is not enabled by default in the mainline defconfig of the board.

The wifi chip needs a NVRAM configuration file which is provided in the
rootfs overlay.

Subject: [PATCH 2/2] ARM: dts: sun7i: Add wifi dt node on Banana Pro
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
The Banana Pro has an AMPAK AP6181 WiFi+Bluetooth module. The WiFi part
is a BCM43362 IC connected to MMC3 of the A20 SoC via SDIO. The IC also
takes a power enable signal via GPIO.
This commit adds a device-tree node to power it up, so the mmc subsys
can scan it, and enables the mmc controller which is connected to it.
As the wifi enable pin of the AP6181 module is not really a regulator,
switch the mmc3 node to the mmc-pwrseq framework for controlling it.
This more accurately reflectes how the hardware actually works.

Banana Pro
Intro
=====
This default configuration will allow you to start experimenting with the
Buildroot environment for the Banana Pro. With the current configuration
it will bring-up the board, and allow access through the serial console.
How to build it
===============
Configure Buildroot:
$ make bananapro_defconfig
Compile everything and build the SD card image:
$ make
How to write the SD card
========================
Once the build process is finished you will have an image called "sdcard.img"
in the output/images/ directory.
Copy the bootable "sdcard.img" onto an SD card with "dd":
$ dd if=output/images/sdcard.img of=/dev/sdX
Notes:
- replace 'sdX' with the actual device with your micro SD card
- you may need to be root to do that (use 'sudo')
Insert the micro SD card in your Banana Pro and power it up. The console
is on the debug TTL UART, 115200 8N1.
Ethernet
==========
# udhcpc -i eth0
Wifi
==========
# wpa_passphrase YOUR_SSID >> /etc/wpa_supplicant.conf
(enter the wifi password and press enter)
# wpa_supplicant -i wlan0 -c /etc/wpa_supplicant.conf -B
# udhcpc -i wlan0
Note:
- replace 'YOUR_SSID' with the actual SSID from your access point
Audio
==========
Connect a headphone to the 3.5mm jack (TRRS). Note, that the Banana Pro
has an on-board microphone, too.
