Subject: [PATCH 8/8] DO-NOT-MERGE: arm64: allwinner: a64: enable Bluetooth On SoPine baseboard
Date:   Fri, 18 Jan 2019 09:02:32 -0800

Precedence: bulk

SoPine has optional RTL8723BS WiFi + BT module, BT is connected to UART1
and uses PL4 as BT reset, PL5 as device wake GPIO, PL6 as host wake GPIO
the I2C controlling signals are connected to R_I2C bus.

Enable it in the device tree.
