From 4e7470ddca671aee2f5d11ba68573c94feddc5c2 Mon Sep 17 00:00:00 2001 From: Tomi Valkeinen Date: Tue, 3 Dec 2013 16:57:40 +0200 Subject: OMAPDSS: add of helpers Add helpers to get ports and endpoints from DT data. These helpers parse v4l2 style ports and endpoints, but compared to the v4l2 helpers, these allow iterating ports and endpoints separately. This is a temporary solution until we get generic code to parse the ports and endpoints.
