Describes the calculation of the UART baud rate clock using a clock
frame. Forgot to add in Kconfig kernel test Robot compilation error
due to COMMON_CLK dependency.

As I already replied on V2 of this patch, you're invited to apply these fixes directly
on the next version of your "Use CCF to describe the UART baud rate clock" patchset
and not as a separate patch.

No, this is broken in linux-next now as the path listed here is in my
tree right now.
I need a fix for it, or I can revert the original.

Please revert the whole patchset, it's not ready yet, neither fully reviewed ands buggy

I have tested that there is no problem with G12A and S4 boards. Can I
merge them first and fix them later if there is any problem?

That's called a regression. That is not how we do things in mainline
There is still a lot of people using GXL boards. Those are still sold even.

This is a link issue. The rest is an unrelated error handling fix.
It should really be sent as two patches.

I'll take the first version of this patch, which just did this portion,
and the rest can be an independant change.

Hi greg and dan,
Thank you very much for your reply. I will make a separate submission
as you suggested to fix Dan's suggestion.
