From 645a2f6e03ed4a998da4b3642d80dd25d371b6b1 Mon Sep 17 00:00:00 2001 From: Uma Shankar Date: Wed, 8 Feb 2017 16:20:50 +0530 Subject: [PATCH] drm/i915: Check for platform specific GPIO config Panel GPIO control should be done based on platform. Add a check to restrict VLV and CHT specific GPIO confirguration, so that they dont apply to other platforms. The VBT spec fails to mention the PMIC backlight control option is valid only for VLV/CHT, and the field may be set to "PMIC" for BXT even if PMIC is not desired or possible.
