I haven't followed i.MX 27 support lately, but this surely should be
done using a pinctrl driver. I see that there is a general pinctrl
driver for i.MX, but a drivers/pinctrl/pinctrl-imx27.c might be
missing. It would probably be a better idea to implement the missing
pinctrl driver, if not already available?

Best regards,

Thomas
