[Freedreno] [PATCH v8 3/4] drm/msm/dpu: revise timing engine programming to support widebus feature

2022-02-17 Thread Kuogee Hsieh
Widebus feature will transmit two pixel data per pixel clock to interface. Timing engine provides driving force for this purpose. This patch base on HPG (Hardware Programming Guide) to revise timing engine register setting to accommodate both widebus and non widebus application. Also horizontal wid
