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.

DEVELOPERS file, remove C++ support.]

Subject: [PATCH 2/2] ARM: dts: sun7i: Add wifi dt node on Banana Pro

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.
