-Readme for Linux device driver for the OmniVision OV511 USB to camera bridge IC
--------------------------------------------------------------------------------
-
-INTRODUCTION:
-
-This is a preliminary version of my OV511 Linux device driver. At the moment,
-it does not do much more than detect the chip and initialize it. As trivial
-as this sounds, it represents many hours of my work. Since OmniVision refused
-to release the full specs to me, I had to write code to probe out the register
-read/write commands. Some code is in place to allow a frame to be grabbed, but
-it is nowhere near complete.
-
-SUPPORTED CAMERAS:
-____________________________________________
-Manufacturer     | Model        | Custom ID 
------------------+--------------+-----------
-D-Link           | DSB-C300	    | 3
-Creative Labs    | WebCam 3     | 21
---------------------------------------------
-
-Any camera using the OV511 and the OV7610 CCD should work with this driver. The
-driver only detects known cameras though, based on their custom id number. If
-you have a currently unsupported camera, the ID number should be reported to you
-in the kernel logs. If you have an unsupported camera, please send me the model,
-manufacturer and ID number and I will add it to the detection code. In the
-meantime, you can add to the code yourself in the function ov511_probe()
-
-WHAT YOU NEED:
-
-- If you want to help with the development, get the chip's specification docs at
-  http://www.ovt.com/omniusbp.html
-
-- A Video4Linux compatible frame grabber program (I recommend vidcat)
-  (see: http://www.exploits.org/v4l/ )
-  
-WHAT NEEDS TO BE DONE:
-
-In short, a lot. 
-
-UPDATE:
-Currently, the control messages are working fine ("vendor commands"; for
-reading and writing the OV511 registers.) The I2C bus commands for reading and
-writing the camera (OV7610) registers are implemented and working, with at least
-one person's camera. The isochronous-in endpoint for video data is finally
-producing data, but since ov511_parse_data() is not implemented you will not see
-a picture yet.
-
-Support for specific CCD's will have to be implemented as well (such as the
-OV7610.) 
-
-The rest of the work will involve implementing support for all the different
-resolutions, color depths, etc. Also, while support for the OV511's proprietary
-lossy compression is apparently not necessary (the code currently disables it,)
-it would be a nice addition as it improves performance quite a bit. OmniVision
-wouldn't tell me how the algorithm works, so we can't really work on that yet.
-Please kindly inform OmniVision that you would like them to release their
-specifications to the Linux community.

-HOW TO CONTACT ME:
-
-You can email me at mmcclelland@delphi.com . Please prefix the subject line
-with "OV511: " so that I am certain to notice your message.
-
-CREDITS:
-
-The code is based in no small part on the CPiA driver by Johannes Erdfelt,
-Randy Dunlap, and others. Big thanks to them for their pioneering work on that
-and the USB stack. Thanks to Bret Wallach for getting camera reg IO and ISOC
-working.
