thermal: intel: int340x: Add missing DVFS support

[PATCH] thermal: intel: int340x: Add missing DVFS support

Posted by Srinivas Pandruvada 8 months, 1 week ago

DVFS (Dynamic Voltage Frequency Scaling) is still supported for DDR
memories on Lunar Lake and Panther Lake.

Add the missing flag PROC_THERMAL_FEATURE_DVFS.
