Complete boot log attached to this e-mail. My tree is based on your clk-
omap-3.8 branch in git://git.linaro.org/people/mturquette/linux.git. I haven't
checked yet if patches for the following warnings have been posted to linux-
omap or other mailing lists.

If you mean removing the explicit handling of dpll4_m5_ck and setting the
cam_mclk rate directly then yes, that's the goal, and I'll submit patches for
that when the successor to thiis patch series will reach mainline. If you mean
something different please elaborate :-)
