From 8530783594f6de14ec6d4b7bf804437d6e1a4f5f Mon Sep 17 00:00:00 2001 From: Jacob Chen Date: Mon, 14 Mar 2016 11:20:18 +0800 Subject: [PATCH] rockchip: video: Add LVDS support in vop driver LVDS have a different display out mode, add code to get right flag. The vop_ip decide display device and the remote_vop_id decide which vop was being used. So we should use the remote_vop_id to set DCLK_VOP.
