From 17f08280cf89baf5e4620fc7af300082bcee7e24 Mon Sep 17 00:00:00 2001 From: Jeson Gao Date: Fri, 7 Mar 2025 13:23:49 +0000 Subject: [PATCH] PM: EM: Rework the depends on for CONFIG_ENERGY_MODEL 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.
