/*
 * OpenThread RCP on the Seeed XIAO nRF54L15.
 *
 * uart20 (P1.09 TX / P1.08 RX) is wired to the onboard CMSIS-DAP USB-serial
 * bridge, so it is both the board's default console and the only UART that
 * reaches the host over USB. The RCP needs that link for spinel, so:
 *
 *   - zephyr,ot-uart  -> uart20  (spinel to otbr-agent on the host)
 *   - zephyr,console  -> uart21  (moved off, or console output would corrupt
 *                                 the spinel byte stream)
 *
 * uart21 (P2.08 TX / P2.07 RX) is exposed on the XIAO edge pads. Nothing needs
 * to be attached; hook up a USB-UART adapter there if you want boot logs.
 *
 * Unlike Nordic's nrf54l15dk overlay, hw-flow-control is NOT set: the XIAO's
 * pinctrl only defines TX and RX for uart20, and the CMSIS-DAP bridge does not
 * carry RTS/CTS. See docs/ for the baud rate this was validated at.
