From 00c92d929ac36848fbe88567ef14af947ab636e4 Mon Sep 17 00:00:00 2001 From: Paulo Zanoni Date: Mon, 21 May 2018 17:25:47 -0700 Subject: [PATCH] drm/i915/icl: unconditionally init DDI for every port On ICP, port present straps (from SFUSE_STRAP PCH register) are no longer supported. Software should determine the presence through BIOS VBT, hotplug or other mechanisms. v2: Improve commit message (Lucas).
