From: Ondrej Jirman <megous@xxxxxxxxxx> The board contains AP6256 WiFi/BT module that has its bluetooth part connected to SoC's UART1 port. Enable this port, and add node for the bluetooth device. Bluetooth part is named bcm4345c5. You'll need a BCM4345C5.hcd firmware file that can be found in the Xulongs's repository for H6: https://github.com/orangepi-xunlong/OrangePiH6_external/tree/master/ap6256 The driver expects the firmware at the following path relative to the firmware directory: brcm/BCM4345C5.hcd Signed-off-by: Ondrej Jirman <megous@xxxxxxxxxx> --- .../dts/allwinner/sun50i-h6-orangepi-3.dts | 19 +++++++++++++++++++ 1 file changed, 19 insertions(+) diff --git a/arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-3.dts b/arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-3.dts index 49d954369087..a9e776446c35 100644 --- a/arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-3.dts +++ b/arch/arm64/boot/dts/allwinner/sun50i-h6-orangepi-3.dts @@ -15,6 +15,7 @@ aliases { serial0 = &uart0; + serial1 = &uart1; }; chosen { @@ -271,6 +272,24 @@ status = "okay"; }; +/* There's the BT part of the AP6256 connected to that UART */ +&uart1 { + pinctrl-names = "default"; + pinctrl-0 = <&uart1_pins>, <&uart1_rts_cts_pins>; + uart-has-rtscts; + status = "okay"; + + bluetooth { + compatible = "brcm,bcm4345c5"; + clocks = <&rtc 1>; + clock-names = "lpo"; + device-wakeup-gpios = <&r_pio 1 2 GPIO_ACTIVE_HIGH>; /* PM2 */ + host-wakeup-gpios = <&r_pio 1 1 GPIO_ACTIVE_HIGH>; /* PM1 */ + shutdown-gpios = <&r_pio 1 4 GPIO_ACTIVE_HIGH>; /* PM4 */ + max-speed = <1500000>; + }; +}; + &usb2otg { /* * This board doesn't have a controllable VBUS even though it -- 2.23.0
