-+ *
-+ * 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.
