[PATCH] usbvision: remove deprecated driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



To quote the TODO of this driver:

--------------------------------------------------------------
The driver is deprecated and scheduled for removal by the end
of 2020.

In order to prevent removal the following actions would have to
be taken:

- clean up the code
- convert to the vb2 framework
- fix the disconnect and free-on-last-user handling (i.e., add
  a release callback for struct v4l2_device and rework the code
  to use that correctly).
--------------------------------------------------------------

Nobody picked this up, so it's time to retire this driver.

- *
- * Copyright (c) 1999-2005 Joerg Heckenbach <joerg@xxxxxxxxxxxxxxxx>
- *
- * This module is part of usbvision driver project.
- *
- * Let's call the version 0.... until compression decoding is completely
- * implemented.
- *
- * This driver is written by Jose Ignacio Gijon and Joerg Heckenbach.
- * It was based on USB CPiA driver written by Peter Pregler,
- * Scott J. Bertin and Johannes Erdfelt
- * Ideas are taken from bttv driver by Ralph Metzler, Marcus Metzler &
- * Gerd Knorr and zoran 36120/36125 driver by Pauline Middelink
- * Updates to driver completed by Dwaine P. Garden
- *
- * TODO:
- *     - use submit_urb for all setup packets
- *     - Fix memory settings for nt1004. It is 4 times as big as the
- *       nt1003 memory.
- *     - Add audio on endpoint 3 for nt1004 chip.
- *         Seems impossible, needs a codec interface.  Which one?
- *     - Clean up the driver.
- *     - optimization for performance.
- *     - Add Videotext capability (VBI).  Working on it.....
- *     - Check audio for other devices
