I was going to comment on the last set but forgot.
My set dealt with the following issues
This set does not have any of the module clocks, which I added
in mine. This is also an issue with the clock and serial drivers
which do not ensure the bus/module clocks have been enabled in
the driver.
Mine also dealt with the multiple parents that some of these
clocks have.
I can try and re-post tonight for discussion.
