From: Imre Deak Date: Thu, 1 Nov 2018 14:04:21 +0000 (+0200) Subject: drm/i915: Move aux_ch to intel_digital_port X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=563d22a0394856a5d984c48b94312ef614fce841;p=openwrt%2Fstaging%2Fblogic.git drm/i915: Move aux_ch to intel_digital_port From ICL onwards all DDI/TypeC ports - even working in HDMI mode - need to know their corresponding AUX CH, so move the field to a common struct. No functional change. v3: - Add code comment about which ports aux_ch is used for.
