i.MX 8M Mini ISL79987 Video Issue

Hello,

I'm working on the i.MX 8M Mini platform.

I have activated the ISL79987 Video Decoder IC.

Although the IC is 4-Channel, I see "video0", "video1", and "video2" under the "/dev" directory.

I am using the following configuration as DTS.

     isl7998x_mipi@3d {
        compatible = "isil,isl79987";
        reg = <0x3d>;

        ports {
          #address-cells = <1>;
          #size-cells = <0>;

          port@0 {
            reg = <0>;
            isl79987_out: endpoint {
              remote-endpoint = <&mipi_csi2_in>;
              data-lanes = <1>;
            };
          };

          port@1 {
            reg = <1>;
            endpoint {
              /*remote-endpoint = <&camera_0>;*/
            };
          };

          port@2 {
            reg = <2>;
            endpoint {
              /*remote-endpoint = <&camera_1>;*/
            };
          };
          
          port@3 {
            reg = <3>;
            endpoint {
              /*remote-endpoint = <&camera_1>;*/
            };
          };
                  
          port@4 {
            reg = <4>;
            endpoint {
              /*remote-endpoint = <&camera_1>;*/
            };
          };
        };
      };

Could you help me with this issue?

Best regards,

Hello,

Thank you for your support.

I have looked through this page but could not find the solution.

How do I update my device tree so that I can see 4 channels of video under /dev directory?

Can you please help me with this?

Best regards.
