6644+ *
6645+ * Revision history
6646+ * 7th May 2003 Initial version.
6647+ * 6th June 2003 Added non module support and AC97 registration.
6648+ * 18th June 2003 Added AUX adc sampling.
6649+ * 23rd June 2003 Did some minimal reformatting, fixed a couple of
6650+ * codec_mutexing bugs and noted a race to fix.
6651+ * 24th June 2003 Added power management and fixed race condition.
6652+ * 10th July 2003 Changed to a misc device.
6653+ * 31st July 2003 Moved TS_EVENT and TS_CAL to wm97xx.h
6654+ * 8th Aug 2003 Added option for read() calling wm97xx_sample_touch()
6655+ * because some ac97_read/ac_97_write call schedule()
6656+ * 7th Nov 2003 Added Input touch event interface, stanley.cai@intel.com
6657+ * 13th Nov 2003 Removed h3600 touch interface, added interrupt based
6658+ * pen down notification and implemented continous mode
6659+ * on XScale arch.
6660+ * 16th Nov 2003 Ian Molton <spyro@f2s.com>
6661+ * Modified so that it suits the new 2.6 driver model.
6662+ * 25th Jan 2004 Andrew Zabolotny <zap@homelink.ru>
6663+ * Implemented IRQ-driven pen down detection, implemented
6664+ * the private API meant to be exposed to platform-specific
6665+ * drivers, reorganized the driver so that it supports
6666+ * an arbitrary number of devices.
6667+ * 1st Feb 2004 Moved continuous mode handling to a separate
6668+ * architecture-dependent file. For now only PXA
6669+ * built-in AC97 controller is supported (pxa-ac97-wm97xx.c).
6670+ * 11th Feb 2004 Reduced CPU usage by keeping a cached copy of both
6671+ * digitizer registers instead of reading them every time.
6672+ * A reorganization of the whole code for better
6673+ * error handling.
6674+ * 17th Apr 2004 Added BMON support.
6675+ * 17th Nov 2004 Added codec GPIO, codec event handling (real and virtual
6676+ * GPIOs) and 2.6 power management.
6677+ * 29th Nov 2004 Added WM9713 support.
6678+ * 4th Jul 2005 Moved codec specific code out to seperate files.
6679+ * 6th Sep 2006 Mike Arthur <linux@wolfsonmicro.com>
6680+ * Added bus interface.

8609+ * Such controller drivers work with a gadget driver. The gadget driver

8617+ * can be enabled and each endpoint can only have one configuration, interface
8618+ * and alternative interface number. Once enabled, these cannot be changed
