++ * Bus glue for Toshiba Mobile IO (TMIO) Controller's OHCI core
++ * (C) Copyright 2005 Chris Humbert <mahadri-usb@drigon.com>
++ *
++ * This is known to work with the following variants:
++ *	TC6393XB revision 3	(32kB SRAM)
++ *
++ * The TMIO's OHCI core DMAs through a small internal buffer that
++ * is directly addressable by the CPU.  dma_declare_coherent_memory
++ * and DMA bounce buffers allow the higher-level OHCI host driver to
++ * work.  However, the dma API doesn't handle dma mapping failures
++ * well (dma_sg_map() is a prime example), so it is unusable.
++ *
++ * This HC pretends be a PIO-ish controller and uses the kernel's
++ * generic allocator for the entire SRAM.  Using the USB core's
++ * usb_operations, we provide hcd_buffer_alloc/free.  Using the OHCI's
++ * ohci_ops, we provide memory management for OHCI's TDs and EDs.  We
++ * internally queue a URB's TDs until enough dma memory is available
++ * to enqueue them with the HC.
++ *

++ *       - 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.

++ *       - 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.

++ *       - 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.
