Yes. The BSP (sun50iw10p1.dtsi) has dynamic-power-coefficient = <190>
on cpu0, and sustainable-power = <1200> on the CPU thermal zone.
The energy model uses the OPP voltages, and Andre points out that the
current OPPs are A100-only and don't fit the A133. So I'd like to fix
the OPPs first, and then add the coefficient as a follow-up, tested with
the power allocator on the K5C. Is that okay with you?
Thanks,
Rajan
