Working on my first driver

I have been working on the touchscreen driver for the past two weeks. In last Friday, it seems that my work had made a milestone. The user land touchscreen calibration and test programs works just fine using tslib.

The touchscreen driver I created conforms to the input layer and event interface of Linux kernel. I have to use "input_register_driver" and "input_register_device" to register my device and the driver. The "probe" function then called.

I have to work out the proc entries and cleanup the code, and write documentation in next week, which should be done without much trouble.
