None other that I'm all in favor. consider patch 2 Acked-by: Philipp Zabel p.zabel@pengutronix.de
Also added Manfred, Tomi and Boris to CC which previously attended in similar discussions.
Previous discussions: http://thread.gmane.org/gmane.linux.kernel.api/12830 http://thread.gmane.org/gmane.comp.video.dri.devel/96240/
I think one of the main observation so far was that the pixel clock polarity is not a property of the mode, and therefor does not fit into the DRM_MODE_FLAG. This has been pointed out nicely by Russel: http://thread.gmane.org/gmane.comp.video.dri.devel/96240/focus=96260
Embedded displays connected through parallel bus make use of the bus_formats field in drm_display_mode. This field defines what kind of bus format the display requires. This patch follows that idea and adds bus_flags. bus_flags can be used to define specific bus properties required by the display, such as pixel clock or data enable polarity...
