From 684eca7dd2187346405180425d3537ed48db3c47 Mon Sep 17 00:00:00 2001 From: Rex Chou Date: Fri, 4 Aug 2023 15:29:59 +0800 Subject: mb/google/nissa/var/craaskov: Configure the external V1p05/Vnn/VnnSx MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This patch configures external V1p05/Vnn/VnnSx rails for Craaskov to follow best practices for power savings – untested though. * Enable the external V1p05, Vnn, VnnSx rails in S0i1, S0i2, S0i3, S3, S4, S5 , S0 states. * Set the supported voltage states. * Set the voltage for v1p05 and vnn. * Set the ICC max for v1p05 and vnn.
