From 595202c304d14e17b1ea1514169346d7cc637206 Mon Sep 17 00:00:00 2001 From: Julien Viard de Galbert Date: Thu, 29 Mar 2018 14:01:01 +0200 Subject: [PATCH] soc/intel/denverton_ns: Add ACPI T-States and P-States Also make soc_get_tss_table public and weak instead of static in intelblock so it can be overridden in denverton.
