Who: Len Brown <len.brown@intel.com> + +---------------------------- + +What: video4linux /dev/vtx teletext API support +When: 2.6.35 +Files: drivers/media/video/saa5246a.c drivers/media/video/saa5249.c + include/linux/videotext.h +Why: The vtx device nodes have been superseded by vbi device nodes + for many years. No applications exist that use the vtx support. + Of the two i2c drivers that actually support this API the saa5249 + has been impossible to use for a year now and no known hardware + that supports this device exists. The saa5246a is theoretically + supported by the old mxb boards, but it never actually worked. + + In summary: there is no hardware that can use this API and there + are no applications actually implementing this API. + + The vtx support still reserves minors 192-223 and we would really + like to reuse those for upcoming new functionality. In the unlikely + event that new hardware appears that wants to use the functionality + provided by the vtx API, then that functionality should be build + around the sliced VBI API instead. +Who: Hans
