i.MX 8M Mini ISL79987 Video Issue

cbl — Fri, 05 Apr 2024 11:37:15 GMT

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.
