-What: corgikbd, spitzkbd, tosakbd driver
-When: 2.6.35
-Files: drivers/input/keyboard/{corgi,spitz,tosa}kbd.c
-Why: We now have a generic GPIO based matrix keyboard driver that
- are fully capable of handling all the keys on these devices.
- The original drivers manipulate the GPIO registers directly
- and so are difficult to maintain.

-What: corgi_ssp and corgi_ts driver
-When: 2.6.35
-Files: arch/arm/mach-pxa/corgi_ssp.c, drivers/input/touchscreen/corgi_ts.c
-Why: The corgi touchscreen is now deprecated in favour of the generic
- ads7846.c driver. The noise reduction technique used in corgi_ts.c,
- that's to wait till vsync before ADC sampling, is also integrated into
- ads7846 driver now. Provided that the original driver is not generic
- and is difficult to maintain, it will be removed later.

+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+Why: The vtx device nodes have been superseded by vbi device nodes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.

+
+ Loongson 2F03 and later have fixed these issues and no workarounds
