Ask the IPU display interface, via ipu_di_adjust_videomode(), to adjust a video mode to meet any DI restrictions. The function takes a subsystem independent videomode, so the drm_display_mode must be converted to videomode first, and then the adjusted mode converted back to a drm_display_mode.
What is the reason to use videomode (apart from it being subsystem independent)? Do we forsee implementation of other output subsystems for the IPU? -- FTTC broadband for 0.8mile line: currently at 9.5Mbps down 400kbps up according to speedtest.net.
