Thanks for your response.
My local changes for VOP. (PART 1)
From 8ce6aeb7708ca81303a3c4c9a94d718d4ab9f2f6 Mon Sep 17 00:00:00 2001

Subject: [PATCH v2] drm/rockchip: vop: add rk3066 vop definitions
This patch adds the rk3066 VOP definitions.
The VOP or LCD Controller serves as interface between
framebuffer memory and a display device (LCD panel or TV set).
This SOC has two symmetrical LCDC's for a dual panel application.
A LCDC has 5 display layers.
Only 3 are used here.
- Video layer 0 (Win0)
- Video layer 1 (Win1)
- OSD layer (Win2)
Win0 and Win1 are exchangeable.
Maximum resolution is 1920x1080.
The LCDC0 output is connected to:
- LCDC0 IO (without IOMUX)
- HDMI TX video input
The LCDC1 output is connected to:
- LCDC1 IO (with IOMUX)
- HDMI TX video input
The HDMI TX input can switch between LCDC0 and LCDC1.
Changes v2:
- Add DSP_HOLD_VALID_INTR
