From: Chen-Yu Tsai <redacted> The NanoPi K2 has a AP6212 WiFi+BT combo module. The WiFi portion is already enabled. The BT part is connected via UART and I2S. Enable the UART and add a device node describing the Bluetooth portion of the module. Signed-off-by: Chen-Yu Tsai <redacted> --- Changes since v1: - added uart-has-rtscts property - added alias for uart_A Hi Neil, Martin, I dropped your review-bys since I added the UART alias and I'm not sure what the policy for those are.

this should not be needed anymore since
a26988e8fef4b258d1b771e0f4b2e3b67cb2e044 ("tty: serial: meson: if no
alias specified use an available id")
IIRC for "newly added" .dts we are only adding the alias for anything
that shows up in /dev/ for the user
meson-khadas-vim3.dtsi for example is not adding an alias for uart_A
(also used for Bluetooth)
Best regards,
