Clock Regression in next-20150130 caused by cb75a8fcd14e

Hi all,

Looks like commit cb75a8fcd14e ("clk: Add rate constraints to clocks") causes a regression on at least omaps where the serial console either does not show anything, or just prints garbage.

Reverting cb75a8fcd14e makes things work again on next-20150130.

Any ideas?

Stephen posted a patch[0] to fix this. I've squashed that into Tomeu's commit that you reference above and my Panda board is booting fine once again.

Please let me know if any other issues pop up. There are new WARNs for OMAP3+ boards introduced by a different patch from Tomeu, but this is really because the OMAP DPLL and FAPLL code are dereferencing struct clk pointers when they should not be and is a separate issue from the constraints patch (with a separate email thread).
