Linux/DRA754: ADV7182 video decoder capture failure on Jacinto 6

Tool/software: Linux

Video capture failure: adv7182 decoder connected to vip

We have connected adv7182 video decoder to vin3a of video input port (vip) on J6 for one of our target. Available driver of adv7182 (drivers/media/i2c/adv7180.c) is used as v4l2 subdev. Subdev registering successful with vip driver and device node for this is coming, but video capture is  failing. Time-out error is coming. Before going for start of streaming, vpdma and vip setup and irq enable seems ok, code flow is as expected. Setting ADV7182 chip to run on free-run mode, it’s clear in status3 register that, it is getting set to run on free-run mode. But no interrupt is seen on vip.

Below are the few details:

1. This is the dts change:

/* ADV7182 Video encoder */

&vip2 {

        status = "okay";

};

&vin3a {

        status = "okay";

        endpoint@0 {

                slave-mode;

                remote-endpoint = <&adv7182>;

        };

};

&i2c2 {

        status = "okay";

        clock-frequency = <400000>;

        adv7182-in@20 {

                compatible = "adi,adv7182";

                reg = <0x20>;

                pwrdwn-gpio = <&gpio6 4 GPIO_ACTIVE_HIGH>;

                reset-gpio = <&gpio6 18 GPIO_ACTIVE_HIGH>;

                intrq-gpio = <&gpio5 16 GPIO_ACTIVE_LOW>;

                remote = <&vip2>;

                port {

                        adv7182: endpoint {

                                buswidth = <8>;

                                remote-endpoint = <&vin3a>;

                                channels = <0>;

                        };

                };

        };

};

1. Setting it to Embedded Sync Bt.656 and 8b data interface.
2. Kernel version is  GSSDK 3.01. *Added “adv7180_s_stream” function extra on top of this, in adv7180.c driver.
3. Log looks like this;

Please let me know if I have to do any configuration in vip driver to support adv7182 video decoder.
