Subject: [PATCH v4 11/11] media: rkisp1: Add UYVY as an output format

Add support for UYVY as an output format. The uv_swap bit in the
MI_XTD_FORMAT_CTRL register that is used for the NV formats does not
work for packed YUV formats. Thus, UYVY support is implemented via
byte-swapping. This method clearly does not work for implementing
support for YVYU and VYUY.

Paul,

I tested this patch series from one of the older submissions and I was
able to get it working, but I could not get the video to capture to
work no matter what resolution or video format I tried. Each time, I
get the same error message: rkisp1 32e10000.isp: start pipeline
failed -32

Do you have an example of how you configured the pipeline and how you
invoked the video capture?

thanks

adam

I have it working now but I had to apply the patch [1] provided by
Tomi in order for it to work properly

Can you send another revision with his patch included in the series?

With that, you can add

Tested-by: Adam Ford <[email protected]> #imx8mp-beacon-kit

Thank you.
