From 8b5f7a62464a24cb83d6290c01d6cf9c8871774a Mon Sep 17 00:00:00 2001 From: Jernej Skrabec Date: Mon, 25 Jun 2018 14:03:01 +0200 Subject: drm: of: Export and rename drm_crtc_port_mask() Function is useful when drm_of_find_possible_crtcs() can't be used and custom parsing is needed. This can happen for example when there is a node with multiple muxes between crtc and encoder.
