Issues when running DT enabled kernel on iMX28 from linux-next

Should one be able to run top of the linux-next on MX28 EVK hardware 
with DT support enabled?
I have attached boot log I see when I try to do that.

Further if one enables, CONFIG_MTD_NAND_GPMI_NAND=y 
CONFIG_MTD_NAND_PLATFORM=y code in 
drivers/mtd/nand/gpmi-nand/gpmi-nand.c doesn't compile because of this code:

         pinctrl = devm_pinctrl_get_select_default(&pdev->dev);
         if (IS_ERR(pinctrl)) {
                 ret = PTR_ERR(pinctrl);
                 goto exit_pin;
         }
