Yes. If this device needs certain pins to be muxed in a certain
configuration, then it needs:
pinctrl-names = "default";
pinctrl-0 = <&pinctrl_some_config_name>;
And then in the imx6q.dtsi, the pinctrl_some_config_name pinctrl
configuration needs to be defined.
But I guess this starts to be a bit off-topic for the U-Boot list. What
about raising the issue with i.MX 6 kernel maintainers on LAKML instead?
Best regards,
Thomas
