Actual display resolution on AM437x

Hi Keigo-san,

Actual display resolution is limited by the maximum pixel clock frequency. From the AM437X Datasheet this is maximum 100MHz in TFT Raster Mode. For 1920x1080@60fps you would need 1920 * 1080 * 60 = 124 416 000 pixel clock periods. If you add ~ 30% overhead for vertical and horizontal sync porches this would make 161 740 800 clock periods per frame or ~ 162MHz pixel clock. You can estimate what can be really achieved by doing the reverse calculations.
