The Wacom Input Driver Gets Enhanced With Linux 3.17

The input subsystem pull request has been submitted for the Linux 3.17 merge window.

Among the items in the input pull sent in by Dmitry Torokhov is a rework of the Wacom driver, which now has been converted to the kernel's HID infrastructure and the USB/Bluetooth support has been unified where as previously Wacom was just treated as a USB driver. This big Wacom driver update was done by Benjamin Tissoires. In the Wacom space, there's also now a driver for serial Wacom devices.

The input pull also has an update to the ALPS driver for enhancing existing hardware support and adding support for some new devices. A new driver part of this pull request is for the Microchip CAP1106, a six-channel capacitive touch controller. Another new input driver for Linux 3.17 is for the Atmel controller on iPAQ h3100/h3600/h3700 series devices. This new driver is based upon an earlier out-of-tree driver from the Linux 2.6.21 kernel days. Given that the iPAQ H3100 was released almost a decade and a half ago and has just a four-bit grayscale display, it's a bit surprising to see a touch input driver finally materialize for the mainline Linux kernel after all of this time. This new driver for old hardware comes while other hardware of almost the same age is being dropped from the Linux kernel. Are any of you still using an iPAQ PDA from the early 2000's?
