From 4e257d9eee23582e36637ce7ea6b14f6f56b1839 Mon Sep 17 00:00:00 2001 From: Mark Yao Date: Wed, 20 Apr 2016 10:41:42 +0800 Subject: [PATCH] drm/rockchip: get rid of rockchip_drm_crtc_mode_config We need to take care of the vop status when use rockchip_drm_crtc_mode_config, if vop is disabled, the function would failed, that is terrible. Save output_type and output_mode into rockchip_crtc_state, it's nice to make them into atomic.
