Subject: sunxi: enable wifi module on Pine64 boards
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=bb9915407bdf24fd45daa49b32715fe3e8e00be0;p=openwrt%2Fstaging%2Fansuel.git

sunxi: enable wifi module on Pine64 boards

The Pine64(+) and the SoPine64 baseboard has an optional BT+WiFi
module, carrying an RTL8723BS. The wifi part is connected via
SDIO, the BT part is connected via UART. The BT part requires
additional code changes in the drivers so we'll skip that until 5.10.
Aside from a DTS patch to enable the wifi module, add the required
packages into the device definitions.
