Since the patch tries to add default selects for all drivers I suspect this
oneliner is the culprit:

@@ -6,7 +6,6 @@ menuconfig ARCH_MXC
        select CLKSRC_IMX_GPT
        select GENERIC_IRQ_CHIP
        select GPIOLIB
-       select PINCTRL
        select PM_OPP if PM
        select SOC_BUS
        select SRAM

Should we just add that one line back?
