[PATCH] power: energy_model: Rework the depends on for CONFIG_ENERGY_MODEL
Posted by Xuewen Yan 1 year, 1 month ago 
From: Jeson Gao <jeson.gao@unisoc.com>

Now not only CPUs can use energy efficiency models, but GPUs
can also use. On the other hand, even with only one CPU, we can also
use energy_model to align control in thermal.
So remove the dependence of SMP, and add the DEVFREQ.

That's true, there are 1-CPU platforms supported. Also, GPU can have
the EM alone.

Hi Rafael,

I noticed that this patch has not been merged yet. Do you have any comments?

Gentle ping. You probably have missed that change for the v6.15 queue

Indeed, I have missed this one.

Now applied as 6.15 material, thanks!
