i.MX6: Increasing VPU frequency

[Jean-Michel Hautbois]

Hi !

I can see in FSL kernel that VPU is configurable to 352M (it defaults
at 264MHz in mainline I think).
In the TRM, it is even specified at 352MHz as a default frequency,
with a maximum of 540MHz.

Would it be possible to allow this clock rating modification if, for
instance, we select a performance governor in cpufreq, or if a coda
encoder is started with 1080p for instance ?
If so, then how is it doable properly ?

Another question is the IPU frequency, but I think it can run only @264MHz...

Thanks,
JM
