From 54c105d6cbcc93507247e82750e83eb49ff5d82b Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ville=20Syrj=C3=A4l=C3=A4?= Date: Fri, 8 Dec 2017 23:37:37 +0200 Subject: [PATCH] drm/i915: No need to power up PG2 for GMBUS on BXT Mime-version: 1.0 Content-type: text/plain; charset=UTF-8 Content-transfer-encoding: 8bit Git-commit: 54c105d6cbcc93507247e82750e83eb49ff5d82b Patch-mainline: v4.16-rc1 References: FATE#322643 bsc#1055900 GMBUS lives in PG1, so no need to power up PG2.
