Version is 4.4.2，I add the adv7180 device on IPU2 CSI1 ,but the board startup errors as shown in attachment.
modified board-imx6q_sabresd.c :
static void adv7180_pwdn(int pwdn)
{
if (pwdn)
gpio_set_value(SABRESD_CSI1_PWN, 1);
else
gpio_set_value(SABRESD_CSI1_PWN, 0);
}
static void mx6q_csi1_io_init(void)
{
if (cpu_is_mx6q())
mxc_iomux_v3_setup_multiple_pads(mx6q_sabresd_csi1_sensor_pads,
ARRAY_SIZE(mx6q_sabresd_csi1_sensor_pads));
else if (cpu_is_mx6dl())
mxc_iomux_v3_setup_multiple_pads(mx6dl_sabresd_csi1_sensor_pads,
ARRAY_SIZE(mx6dl_sabresd_csi1_sensor_pads));
if (cpu_is_mx6q())
mxc_iomux_set_gpr_register(1, 20, 1, 1);//by ruofeng
//mxc_iomux_set_gpr_register(1, 19, 1, 1);
else if (cpu_is_mx6dl())
//mxc_iomux_set_gpr_register(13, 0, 3, 4);
mxc_iomux_set_gpr_register(13, 3, 3, 4);
}

Where is my wrong Or what's the problem I overlooked？ HELP!
