I tested 3.13-rc7-dt-clks-v13 on top of a next branch I am working on
with a OMAP4460 and it's working fine.

A couple of things I noticed in the boot log:
[ 0.000000] ti_dt_clocks_register: failed to lookup clock node bandgap_fclk
[ 0.000000] smp_twd: clock not found -2

I am get the bandgap_fclk clock lookup fail since it doesn't exist on
4460 and I guess the bandgap_ts_fclk clock will fail the same way on
4430. So maybe you need to differentiate between 4460 and 4430 in
clk-44xx.c to get rid of this warning.

As for the smp_twd clock I assume we can add "clocks =
<&mpu_periphclk>" to local-timer at 48240600 in omap4.dtsi to get rid of
the warning. I can cook up a patch here if it is the right thing to
do.
I think the smp_twd warning existed before I applied this patch set.
