The U-Boot fixup won't work with this. U-Boot patches the frequency directly
into the clockgen node (BTW, this is another reason to preserve the generic
1.0/2.0 compatible string). The new binding does not require an input clock
node when it is provided as clock-frequency directly in the clockgen node --
and the sysclk node was not in my original patch (nor did you note that you
made changes from that original). Why did you add it?
I would just remove it when applying, but I'm concerned that this indicates a
lack of testing (and I don't have the hardware access to test it myself,
except on t4240) -- unless the 100 MHz sysclk just happened to be correct on
the machines you tested (which would also be a test coverage problem)?
