Subject: [PATCH 098/170] arm64:dts: sun50i-a64-pine64 enable Bluetooth
|
||
|
|
|
||
|
|
Pine64 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.
