From 0678bea4b6dcd6c3e90ca400fbb5d5ec65f694f4 Mon Sep 17 00:00:00 2001 From: Duncan Laurie Date: Thu, 3 Sep 2015 16:22:49 -0700 Subject: glados: Enable DPTF - Add ACPI code for DPTF support with placeholder thresholds - Do not have custom PDL for mainboard - Do not have enable charger control for DPTF as there is already a complicated charge profile in the EC. We may still want to enable this but it would need to be tuned to work well with the EC profile.
