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).

Seems Linux next is broken again. Now we omaps get tons of:

clock: dpll_abe_ck failed transition to 'locked'
WARNING: CPU: 0 PID: 1 at drivers/clk/clk.c:925 clk_disable+0x28/0x34()

and 

WARNING: CPU: 0 PID: 1 at arch/arm/mach-omap2/dpll3xxx.c:436
omap3_noncore_dpll_enable+0xdc/0x10c()

Regards,

Tony
