From f4a6de855eae10bba725c6dae65fa1e351c9cd25 Mon Sep 17 00:00:00 2001 From: Mark Yao Date: Sat, 29 Dec 2018 14:33:14 +0100 Subject: [PATCH] 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.
