|
* iPAQ H1940 touchscreen support
|
|
*
|
|
* ChangeLog
|
|
*
|
|
* 2004-09-05: Herbert Pötzl <herbert@13thfloor.at>
|
|
* - added clock (de-)allocation code
|
|
*
|
|
* 2005-03-06: Arnaud Patard <arnaud.patard@rtp-net.org>
|
|
* - h1940_ -> s3c24xx (this driver is now also used on the n30
|
|
* machines :P)
|
|
* - Debug messages are now enabled with the config option
|
|
* TOUCHSCREEN_S3C_DEBUG
|
|
* - Changed the way the value are read
|
|
* - Input subsystem should now work
|
|
* - Use ioremap and readl/writel
|
|
*
|
|
* 2005-03-23: Arnaud Patard <arnaud.patard@rtp-net.org>
|
|
* - Make use of some undocumented features of the touchscreen
|
|
* controller
|
