[RFC PATCH 0/2] Introduce runtime modifiable Energy Model

[Lukasz Luba]

Hi all,

This is a follow-up patch aiming to show the users of the proposed
runtime modifiable Energy Model framework. The patches and discussion is
available here [1]. I didn't wanted to add more complexity in that
already big EM patch set and planned to add more users later.
This patch set is one of the first user. I have talked about the chip
binning in a few conferences and the need to update the EM after boot.
This Exynos is one of the platforms which adjust voltage after the EM
is registered. This is perfectly fine and alloed in the kernel, even
from a module so very late. The EM framework should just allow to
modify the power values after that.

This patch set will have to wait for merging of the dependet main EM
change. 

Regards,
Lukasz Luba
