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(+)
