So thank you all the > people who are responsible for the Media Controller and the OMAP ISP driver. This may be a stupid question, but how much changes are there between this driver and the OMAP 3 ISP driver? I understand that not all the blocks are there. Are there any major functional differences between those in Davinci and those in OMAP 3? Could the OMAP 3 ISP driver made support Davinci ISP as well? There are number of possible improvements that still should be made to the OMAP 3 ISP driver so this way both of the driver would easily get them. To mention some: - Multiple output pipeline - Switch to videobuf2 - Switch to GENIRQ Cc Laurent. Regards, -- Sakari Ailus sakari.ailus@iki.fi
