From 2c9de49a971497fadaf5272fd1bacee7a316dbfc Mon Sep 17 00:00:00 2001 From: Felix Held Date: Thu, 23 Mar 2023 23:57:44 +0100 Subject: soc/amd: introduce and use get_pstate_core_uvolts for SVI2 and SVI3 Since SVI3 has the CPU voltage ID split into two parts, a serial voltage ID version specific function is needed to get the raw core VID value. This will allow making get_pstate_core_power common for all AMD CPUs in a follow-up patch.
