[PATCH 4/4] ARM64: dts: meson-gxbb-vega-s95: enable the Bluetooth module

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



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 -
