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 --- 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.
