It's preferable not to rely on the value that comes from the bootloader and explicitly describe the value in the DT. For the MX6QDL_PAD_DI0_PIN4__IPU1_DI0_PIN04 pin: look at its IOMUXC_SW_PAD_CTL register in the i.MX6Q Reference Manual. It is called IOMUXC_SW_PAD_CTL_PAD_DI0_PIN04 and its reset value is 0x1b0b0. So this entry would become: MX6QDL_PAD_DI0_PIN4__IPU1_DI0_PIN04 0x1b0b0
