This is identical for all boards which inherit meson-gx-p23x-q20x: - GXL S905D P230 - GXL S905D P231 - GXM S912 Q200 - GXM S912 Q201 To get the HCI interface up one has to install bluez-utils and run: hciattach -s115200 /dev/ttyAML1 bcm43xx 2000000 flow - Signed-off-by: Martin Blumenstingl --- arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi | 12 +++++++++++- 1 file changed, 11 insertions(+), 1 deletion(-) diff --git a/arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi b/arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi index 7a078bef04cd..7db779048091 100644 --- a/arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi +++ b/arch/arm64/boot/dts/amlogic/meson-gx-p23x-q20x.dtsi @@ -48,6 +48,7 @@ / { aliases { serial0 = &uart_AO; + serial1 = &uart_A; }; chosen { @@ -94,12 +95,21 @@ sdio_pwrseq: sdio-pwrseq { compatible = "mmc-pwrseq-simple"; - reset-gpios = <&gpio GPIOX_6 GPIO_ACTIVE_LOW>; + reset-gpios = <&gpio GPIOX_6 GPIO_ACTIVE_LOW>, + <&gpio GPIOX_17 GPIO_ACTIVE_LOW>; clocks = <&wifi32k>; clock-names = "ext_clock"; }; }; +/* This is connected to the Bluetooth module of the wifi/BT combo chip: */ +&uart_A { + status = "okay"; + pinctrl-0 = <&uart_a_pins &uart_a_cts_rts_pins>; + pinctrl-names = "default"; + uart-has-rtscts; +}; + /* This UART is brought out to the DB9 connector */ &uart_AO { status = "okay"; -- 2.11.0
