From 39d3021b164429da00f4c4c79b2eccb42f416382 Mon Sep 17 00:00:00 2001 From: Furquan Shaikh Date: Thu, 1 Mar 2018 18:08:06 -0800 Subject: mb/google/poppy/variants: Set pch_trip_temp to 75C Similar to Soraka, this change sets the pch_trip_temp value to 75C. This is important so that PMC can shutdown the thermal sensor when CPU is in C-state and DTS temp <= pch_trip_temp.
