Hi Manju, I've reviewed the other patches as well. The only one for which I had comments was patch 2/6. However, what I think would be useful here is to have an overview document, either as part of a source or header, or as a separate text document. It is not easy to get a good overview of how everything fits together, and a document that describes the various parts and how they fit together would be very benificial. I am thinking in particular of vendors building a new board based on this device: how and where do you define new i2c display devices, how are they initialized, etc. Regards, Hans On Monday, November 08, 2010 15:54:05 Manjunath Hadli wrote: > This driver is written for Texas Instruments's DM644X VPBE IP. > This SoC supports 2 video planes and 2 OSD planes as part of its > OSD (On Screen Display) block.
