Hi Guennadi, I found in soc_camera when video device is opened, default format is applied sensor. I think this is the right thing to do, be it also means a lot of i2c transactions. I think in case of app wants to query drivers capability, it do a quick open-query-close, expecting only

[media] soc_camera: suggest to postpone applying default format

How to express planar formats with mediabus format code?

Hi, I know the title looks crazy, but here is our problem: In our SoC based ISP, the hardware can be divide to several blocks. Some blocks can do color space conversion(raw to YUV interleave/planar), others can do the pixel re-order(interleave/planar/semi-planar conversion, UV planar switch). We

Re: OMAP3 ISP DQBUF hangs

Hi Tom you are right. it seems that the list of the ccdc has no buffer left, because the printk(TOM ccdc_isr_buffer ERROR 1 ##\n); is shown in my log. But I don't understand what I need to do to solve the problem. What I do is: - configure the pipeline - open the video device - do
