++ * Notes:
++ *
++ * Features:
++ * - supports WM9705, WM9712, WM9713
++ * - polling mode
++ * - continuous mode (arch-dependent)
++ * - adjustable rpu/dpp settings
++ * - adjustable pressure current
++ * - adjustable sample settle delay
++ * - 4 and 5 wire touchscreens (5 wire is WM9712 only)
++ * - pen down detection
++ * - battery monitor
++ * - sample AUX adc's
++ * - power management
++ * - codec GPIO
++ * - codec event notification
++ * Todo
++ * - Support for async sampling control for noisy LCD's.
++ *
++ * Revision history
++ * 7th May 2003 Initial version.
++ * 6th June 2003 Added non module support and AC97 registration.
++ * 18th June 2003 Added AUX adc sampling.
++ * 23rd June 2003 Did some minimal reformatting, fixed a couple of
++ * codec_mutexing bugs and noted a race to fix.
++ * 24th June 2003 Added power management and fixed race condition.
++ * 10th July 2003 Changed to a misc device.
++ * 31st July 2003 Moved TS_EVENT and TS_CAL to wm97xx.h
++ * 8th Aug 2003 Added option for read() calling wm97xx_sample_touch()
++ * because some ac97_read/ac_97_write call schedule()
++ * 7th Nov 2003 Added Input touch event interface, stanley.cai@intel.com
++ * 13th Nov 2003 Removed h3600 touch interface, added interrupt based
++ * pen down notification and implemented continous mode
++ * on XScale arch.
++ * 16th Nov 2003 Ian Molton <spyro@f2s.com>
++ * Modified so that it suits the new 2.6 driver model.
++ * 25th Jan 2004 Andrew Zabolotny <zap@homelink.ru>
++ * Implemented IRQ-driven pen down detection, implemented
++ * the private API meant to be exposed to platform-specific
++ * drivers, reorganized the driver so that it supports
++ * an arbitrary number of devices.
++ * 1st Feb 2004 Moved continuous mode handling to a separate
++ * architecture-dependent file. For now only PXA
++ * built-in AC97 controller is supported (pxa-ac97-wm97xx.c).
++ * 11th Feb 2004 Reduced CPU usage by keeping a cached copy of both
++ * digitizer registers instead of reading them every time.
++ * A reorganization of the whole code for better
++ * error handling.
++ * 17th Apr 2004 Added BMON support.
++ * 17th Nov 2004 Added codec GPIO, codec event handling (real and virtual
++ * GPIOs) and 2.6 power management.
++ * 29th Nov 2004 Added WM9713 support.
++ * 4th Jul 2005 Moved codec specific code out to seperate files.
++ * 6th Sep 2006 Mike Arthur <linux@wolfsonmicro.com>
++ * Added bus interface.

++ * This driver handles the USB Device Controller (UDC) in Intel's PXA 27x
++ * series processors.
++ *
++ * Such controller drivers work with a gadget driver. The gadget driver
++ * returns descriptors, implements configuration and data protocols used
++ * by the host to interact with this device, and allocates endpoints to
++ * the different protocol interfaces. The controller driver virtualizes
++ * usb hardware so that the gadget drivers will be more portable.
++ *
++ * This UDC hardware wants to implement a bit too much USB protocol. The
++ * biggest issue is that the endpoints have to be setup before the controller
++ * can be enabled and each endpoint can only have one configuration, interface
++ * and alternative interface number. Once enabled, these cannot be changed
++ * without a controller reset.
++ *
++ * Intel Errata #22 mentions issues when changing alternate interface.
++ * The exact meaning of this remains uncertain as gadget drivers using alternate
++ * interfaces such as CDC-Ethernet appear to work...
