Some of the iMX25 pins have not an associated configuration register so when they are configured the standard way through the device tree the kernel complains with: imx25-pinctrl 43fac000.iomuxc: Pin(MX25_PAD_EXT_ARMCLK) does not support config functionCould you please share your device tree that causes this warning? Shouldn't you pass 0x80000000 in the devicetree for this pad then? 0x80000000 means that the kernel should not touch the PAD_CTL register and use the default configuration from the bootloader/POR.
