Widebus feature will transmit two pixel data per pixel clock to interface.
This feature now is required to be enabled to easy migrant to higher
resolution applications in future. However since some legacy chipsets
does not support this feature, this feature is enabled base on chip's
hardware
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
