This takes the Bluetooth module out of reset (the reset line is connected to GPIOX_20) and enables uart_A which is used to configure the module. This is common for all Vega S95 boards. The device can then be initialized by running the hciattach tool: hciattach -s115200 /dev/ttyAML1 bcm43xx 2000000 flow - Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> --- arch/arm64/boot/dts/amlogic/meson-gxbb-vega-s95.dtsi | 9 +++++++++ 1 file changed, 9 insertions(+)diff --git a/arch/arm64/boot/dts/amlogic/meson-gxbb-vega-s95.dtsi b/arch/arm64/boot/dts/amlogic/meson-gxbb-vega-s95.dtsi index ab497126c9a3..9e0a13b1ac93 100644 --- a/arch/arm64/boot/dts/amlogic/meson-gxbb-vega-s95.dtsi +++ b/arch/arm64/boot/dts/amlogic/meson-gxbb-vega-s95.dtsi@@ -47,6 +47,7 @@ aliases { serial0 = &uart_AO; + serial1 = &uart_A; }; chosen {@@ -100,6 +101,14 @@ }; }; +/* This is connected to the Bluetooth module of the wifi/BT combo chip: */
Personally I would just say "Connected to the .... chip" or even just "Bluetooth .... chip", without trailing colon, for consistency.
