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?
Regards,
Tony

The patch seems to have some problems.

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.
[0] http://lkml.kernel.org/r/<20150131013158.GA4323@codeaurora.org>
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).

Mike

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()

Tony
