* Harmony chipset 'modus operandi'.
* - This chipset is found in some HP 32bit workstations, like 712, or B132 class.
* most of controls are done through registers. Register are found at a fixed offset
* from the hard physical adress, given in struct dev by register_parisc_driver.
*
* Playback and recording use 4kb pages (dma or not, depending on the machine).
* *
* Most of PCM playback & capture is done through interrupt. When harmony needs * This program is distributed in the hope that it will be useful,
* a new buffer to put recorded data or read played PCM, it sends an interrupt. * but WITHOUT ANY WARRANTY; without even the implied warranty of
* Bits 2 and 10 of DSTATUS register are '1' when harmony needs respectively * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
* a new page for recording and playing. * GNU General Public License for more details.
* Interrupt are disabled/enabled by writing to bit 32 of DSTATUS.
* Adresses of next page to be played is put in PNXTADD register, next page
* to be recorded is put in RNXTADD. There is 2 read-only registers, PCURADD and
* RCURADD that provides adress of current page.
* *
* Harmony has no way to control full duplex or half duplex mode. It means * You should have received a copy of the GNU General Public License
* that we always need to provide adresses of playback and capture data, even * along with this program; if not, write to the Free Software
* when this is not needed. That's why we statically alloc one graveyard * Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
* buffer (to put recorded data in play-only mode) and a silence buffer.
* *
* Bitrate, number of channels and data format are controlled with * Notes:
* the CNTL register. * - graveyard and silence buffers last for lifetime of
* the driver. playback and capture buffers are allocated
* per _open()/_close().
* *
* Mixer work is done through one register (GAINCTL). Only input gain, * TODO:
* output attenuation and general attenuation control is provided. There is
* also controls for enabling/disabling internal speaker and line
* input.
* *
* Buffers used by this driver are all DMA consistent.
