Subject[PATCH] arm64: dts: meson-gxbb: nanopi-k2: Enable Bluetooth
Date
From: Chen-Yu Tsai <wens@csie.org>

The NanoPi K2 has a AP6212 WiFi+BT combo module. The WiFi portion is
already enabled. The BT part is connected via UART and I2S.

Enable the UART and add a device node describing the Bluetooth portion
of the module.
