From 758c1715398f63a6b111ec086b0619d43bda17e6 Mon Sep 17 00:00:00 2001 From: robbie zhang Date: Fri, 11 Dec 2015 15:21:57 -0800 Subject: google/chell: Add VR config settings Use the Kunimitsu settings as baseline, except Psi4Enable set to 0 due to a known issue (not able to hit S0ix) on glados. The VR settings will then need to be updated per the board VR design.
