-/*
- Supported devices:
- *Lifeview FlyCam Supra (using the Philips saa7111a chip)
-
- Does any other model using the w9966 interface chip exist ?
-
- Todo:
-
- *Add a working EPP mode, since DMA ECP read isn't implemented
- in the parport drivers. (That's why it's so sloow)
-
- *Add support for other ccd-control chips than the saa7111
- please send me feedback on what kind of chips you have.
-
- *Add proper probing. I don't know what's wrong with the IEEE1284
- parport drivers but (IEEE1284_MODE_NIBBLE|IEEE1284_DEVICE_ID)
- and nibble read seems to be broken for some peripherals.
-
- *Add probing for onboard SRAM, port directions etc. (if possible)
-
- *Add support for the hardware compressed modes (maybe using v4l2)
-
- *Fix better support for the capture window (no skewed images, v4l
- interface to capt. window)
-
- *Probably some bugs that I don't know of
-
- Please support me by sending feedback!
-
- Changes:
-
- Alan Cox: Removed RGB mode for kernel merge, added THIS_MODULE
- and owner support for newer module locks

- * per pixel and order of subsamples. Numerical values are sorted using generic
- * numerical sort order (8 thus comes before 10).
