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? It's not available, and yes, it should be implemented. Adding the iomux setup to a i.MX27 SoC specific file is not a good idea.
