ADV7281M driver

yurykocherov — Wed, 28 Jan 2015 11:21:07 GMT

Hello!

I am trying to get CSI video from ADV7281M on UDOO Quad board (iMX6Q). I found "adv7280_mipi_csi2_tvin.c" in the kernel sources and plug it in the config.

Then I found that the initial code for UDOO does not manage ADV7280, so I have added necessary code. Right now I see that ADV7280 driver registered by system (probe function called), but there is no /dev/videoX file for my ADV7280 instance. I guess the reason is "adv7280_mipi_csi2_tvin.c" provides only I2C registration... not V4L.

I found that another board (mx6q sabreauto ???) also uses ADV7280, but it is not clear how...

So there are questions:

- how to use ADV7280 without V4L?

- is anyone uses ADV7280 and have working driver?

/Regards, Yury.

Update:

Well, I have updated "adv7280_mipi_csi2_tvin" (I have added V4L2 routines to it). But unfortunately I always have (even with free run mode):

- ERROR: v4l2 capture: mxc_v4l_dqueue timeout enc_counter 0

I think the issue with my MIPI CSI settings...

Does anybody have any suggestions what is wrong?

Regards, Yury.

P/s/

I have enabled debug output in the sources, and below some registers values:
