Thanks for trying the patch out. This patch isn't meant to fix the clk
crash that you mentioned on another thread. I had made the following patch for
that: https://lore.kernel.org/lkml/YvqTvuqSll30Rv2k@google.com/. Have
you been able to give that a shot yet? If not can you please test with the
patch in this e-mail and that patch?

Please make sure you do not include this patch as it is known to cause
deadlocks: https://lore.kernel.org/lkml/YvXhJRlHN9OAIA5l@google.com/.

Did you test imx25-pdk emulations with just v1 of this patch previously?

Thanks,
Isaac
