imx6 + CSI parallel camera + mxc capture driver + kernel 3.16

DeLe — Wed, 04 Mar 2015 07:34:40 GMT

Hi@all,

I'm using a custom board with an imx6DL and the kernel version 3.16! At the CSI0 interface I've an ADV7180 with a 8bit data connection!

I want to use the MXC v4l capture driver (VIDEO_MXC_CAPTURE) but this is using deprecated interface devices VIDEO_V4L2_INT_DEVICE.

I think the capture driver have to use the v4l2 sub devices (VIDEO_V4L2_SUBDEV_API)!?

If I try to activate the VIDEO_MXC_CAPTURE I got many linker errors, due to missing VIDEO_V4L2_INT_DEVICE components!

I think it could'nt be the right way to reactivate the deprecated VIDEO_V4L2_INT_DEVICE functionality, but I need an alternativ solution in the 3.16 kernel.

Is there any patch for that?

Thanks

Denis

Hi Denis,

Have you checked if the issue is also included on the official Freescale release BSP? I’m afraid that we haven’t tested kernel 3.16, as the latest BSP release is L3.10.53 (Yocto project).

Hope this information will be useful for you.

Best regards!

Hello Peter,

sorry for the late answer...

we didn't get a solution from community. So we improve the driver to support the newer SUBDEV_API interface.
