sensors) wich are also supported by the gspca_zc3xx driver
(which supports 53 USB-ID's in total)
Who: Hans de Goede <hdegoede@redhat.com>
+
+----------------------------
+
+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.
+Who: Eric Miao <eric.y.miao@gmail.com>
+
+----------------------------
+
+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.
