The mezzanine board carries an E key type M.2 slot. This is connected to USB, SDIO and UART0. Enable sdio and uart0 for use with e.g. wlan and/or bt M.2 cards. Signed-off-by: Markus Reichl <redacted> --- Wifi via SDIO has been tested with Laird ST60-2230C (Marvell 88W8997) Bluetoth via USB has been tested with Intel 9260 Bluetooth via UART has not been tested. --- --- .../dts/rockchip/rk3399-roc-pc-mezzanine.dts | 21 +++++++++++++++++++ 1 file changed, 21 insertions(+)
