TE026 csi camera port, how enable v4l2?

[Shogun]

Hi there,

so far I use the device-tree definitions found in TE0726-rpi_hw_ips-vivado_2015.4-build_34_20160602111427, it covers a lot of Zynqberry's hardware but there is no definitions in system-top.dts for the camera.

It is obvious that VIDEO_XILINX and VIDEO_V4L2 need to be enabled in the kernel settings, but I have no idea how to configure in system-top.dts or whatever else might be neccessary.

Can someone share with us, please?

Thanks
Michael

the  linux video way is complex

what we have done is only setting up framebuffer for the camera, this works, we should also have dts for this. But in the hdmi+camera design the camera was set to disabled to make the image boot without camera attached.

V4L2, etc it is really complex set of stuff, same for the DRM
so while it may be possible we do not have full setup for V4L2 setup
