Subject: [PATCH 144/146] arm64: allwinner: a64: enable Bluetooth On Pinebook
|
|
|
|
Pinebook has an RTL8723CS WiFi + BT chip, 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.
