Sorry for the late reply, and thank you for providing this information.

Your email isn't in a valid patch format. Could you perhaps use git to
format it as a patch and have the message above and links below be
part of the commit message? It should also have your Signed-off-by.

Alternatively, if you don't feel like doing it, I will create a patch
based on your email and diff. I would still need your Signed-off-by,
which you can give by simply replying here.

This is actually invalid. The maximum channel width cannot exceed the
band's width. Previously our database tool allowed it but the kernel
did not, causing the kernel to fail to load the database. The tool
was recently "fixed" to disallow this as well. So this needs to be 80 MHz.

The links you provided mention that the 5250-5350 and 5470-5725 bands
require TPC. Unfortunately neither the kernel nor this database supports
this. We have worked around this by lowering the power limits of these
bands by 3 dBm, as specified by EN 301 893.


Thanks
