Current functionality is somewhat limited: driver assumes that there is only one active IPU unit (IPU1) and that video output is DI0 and video mode is 1024x768. For more advanced functionality driver requires proper clock management which is work in progress. At the moment driver assumes that pixel clock is configured by u-boot for 1026x768 mode.
