Sorry for my bad English first.
I had a question about the warning message:
"imx-ipuv3 imx-ipuv3.1: WARNING: adapt panel end blank lines"
I trace the source code "ipu_disp.c" and find that the message is printed in the function "adapt_panel_to_ipu_restricitions"
In the code, we can know that if the vertical back porch less than 2, it will adjust to 2.
If any document mention this limitation?
