From 871bcdfea68560991bd650406e47a801ab9d635d Mon Sep 17 00:00:00 2001
From: Vincent Abriou
Date: Fri, 31 Jul 2015 11:32:13 +0200
Subject: drm/sti: code clean up

Purpose is to simplify the STI driver:
- remove layer structure
- consider video subdev as part of the compositor (like mixer subdev)
- remove useless STI_VID0 and STI_VID1 enum
