From 7caaef332abaae872ddd2cd65bbe8a8bc0d8f5cc Mon Sep 17 00:00:00 2001 From: Jani Nikula Date: Wed, 16 Mar 2016 12:43:34 +0200 Subject: [PATCH] drm/i915/bios: drop has_mipi in favor of intel_bios_is_dsi_present Favor a single point of truth instead of duplicating the information. The change also filters out unsupported DSI ports at this stage, accepting only ports A and C, instead of waiting until the port checks.
