From d0815082cb98487618429b62414854137049b888 Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Thu, 28 Sep 2017 10:55:59 +0300 Subject: [PATCH] drm/i915/bios: parse DDI ports also for CHV for HDMI DDC pin and DP AUX channel Organization: Intel Finland Oy - BIC 0357606-4 - Westendinkatu 7, 02160 Espoo Cc: Jani Nikula While technically CHV isn't DDI, we do look at the VBT based DDI port info for HDMI DDC pin and DP AUX channel. (We call these "alternate", but they're really just something that aren't platform defaults.) In commit e4ab73a13291 ("drm/i915: Respect alternate_ddc_pin for all DDI ports") Ville writes, "IIRC there may be CHV system that might actually need this." I'm not sure why there couldn't be even more platforms that need this, but start conservative, and parse the info for CHV in addition to DDI.
