From eab314f5909dba208d4cb7dc5aac6ee707d5d171 Mon Sep 17 00:00:00 2001 From: Jacob Chen Date: Mon, 14 Mar 2016 11:20:14 +0800 Subject: dm: video: Add a operation to display uclass The current display class only allow to get timing from edid. So add a operation to get timing directly from driver. In driver, I will use fdtdec_decode_display_timing to get timing.
