Add the adv7180 on imx6dl

542411838 — Wed, 06 Jan 2016 02:58:33 GMT

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!

Hi yanfeng

i.MX6DL has only one IPU1, for ADV7180 examples one can look at

这个链接不存在了，我也有IMX6U/IMX6DL 驱动ADV7180的问题， 6S/6D都没有问题， 6U就花屏
