   3  *
   4  *      This is a sound driver for ASP's and Lasi's Harmony sound chip
   5  *      and is unlikely to be used for anything other than on a HP PA-RISC.
   6  *
   7  *      Harmony is found in HP 712s, 715/new and many other GSC based machines.
   8  *      On older 715 machines you'll find the technically identical chip
   9  *      called 'Vivace'. Both Harmony and Vicace are supported by this driver.
  10  *
  11  *  this ALSA driver is based on OSS driver by:

  19  * - spin locks
  20  * - implement non-consistent DMA pages

  30  * Harmony chipset 'modus operandi'.
  31  * - This chipset is found in some HP 32bit workstations, like 712, or B132 class.
  32  * most of controls are done through registers. Register are found at a fixed offset
  33  * from the hard physical adress, given in struct dev by register_parisc_driver.
  34  *
  35  * Playback and recording use 4kb pages (dma or not, depending on the machine).
  36  *
  37  * Most of PCM playback & capture is done through interrupt. When harmony needs
  38  * a new buffer to put recorded data or read played PCM, it sends an interrupt.
  39  * Bits 2 and 10 of DSTATUS register are '1' when harmony needs respectively
  40  * a new page for recording and playing.
  41  * Interrupt are disabled/enabled by writing to bit 32 of DSTATUS.
  42  * Adresses of next page to be played is put in PNXTADD register, next page
  43  * to be recorded is put in RNXTADD. There is 2 read-only registers, PCURADD and
  44  * RCURADD that provides adress of current page.
  45  *
  46  * Harmony has no way to controll full duplex or half duplex mode. It means
  47  * that we always need to provide adresses of playback and capture data, even
  48  * when this is not needed. That's why we statically alloc one graveyard
  49  * buffer (to put recorded data in play-only mode) and a silence buffer.
  50  *
  51  * Bitrate, number of channels and data format are controlled with
  52  * the CNTL register.
  53  *
  54  * Mixer work is done through one register (GAINCTL). Only input gain,
  55  * output attenuation and general attenuation control is provided. There is
  56  * also controls for enabling/disabling internal speaker and line
  57  * input.
  58  *
  59  * Buffers used by this driver are all DMA consistent. Since harmony is
  60  * not "real" pci device, we use a fake struct pci_dev for
  61  * pci_alloc_consistent().
  62  * (note that some machines -712 for ex.- don't implement DMA consistent
  63  * memory, so we will need to use kmalloc instead)
