Well, without this patch the SoC runs at 1.2GHz so it seems like the
fuse indicates that it is possible. But with a fair amount of IPs
enabled and high load the board becomes unstable (display
flickering/blanks, ethernet package drops, ...). I guess CompuLab
allowed 1.2GHz at first and then realized that it is a bad idea (at
least for some boards).

Is there any way to influence the fuse (e.g. from the
firmware/bootloader) or do you have another proposal on how to fix this
issue?

Ok, understood. So the mx6q fuse indicates that 1.2GHz operation is
possible on , but the board itself does not behave nicely at this
frequency.

Maybe you could send a v2 of this patch that matches the operating
points form mx6qdl.dtsi and remove only the 1.2GHz entry and put the
explanation you gave us here in the dts and commit log.

Will do.

Thanks,
Christopher
