No, this not on my TODO list [1].

Current prio:
- Raspberry Pi 3+
- fixes and improvements for Raspberry Pi 3 DT
- VCHIQ data corruption

Implementing/Porting the cpufreq driver is only half of the work. Also all drivers which depend on the VPU core clock should be able to handle a frequency change (sdhost, i2c, aux uart comes to my mind). But i will be happy if somebody takes care of it.

Is this a critical feature for you?

Best regards
Stefan
