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...
