The board integrates an on-board mux to route shared signals to either CAN2 or PDM (MICFIL). The mux is controlled by a GPIO. Add a pinctrl-based multiplexer node to describe this routing and ensure proper probe ordering of the dependent devices. Signed-off-by: Frank Li <Frank.Li@nxp.com>
Can you please explain what is wrong with the current approach? Current dtb imx8mp-evk.dtb is used to enable PDM MICFIL and sets proper pinctrl routing.
