- * Harmony chipset driver
+/* Hewlett-Packard Harmony audio driver
*
- * This is a sound driver for ASP's and Lasi's Harmony sound chip
- * and is unlikely to be used for anything other than on a HP PA-RISC.
+ * This is a driver for the Harmony audio chipset found
+ * on the LASI ASIC of various early HP PA-RISC workstations.
*
- * Harmony is found in HP 712s, 715/new and many other GSC based machines.
- * On older 715 machines you'll find the technically identical chip
- * called 'Vivace'. Both Harmony and Vivace are supported by this driver.

- * 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.
+ * This program is free software; you can redistribute it and/or modify
+ * it under the terms of the GNU General Public License, version 2, as
+ * published by the Free Software Foundation.
*
- * Playback and recording use 4kb pages (dma or not, depending on the machine).
+ * This program is distributed in the hope that it will be useful,
+ * but WITHOUT ANY WARRANTY; without even the implied warranty of
+ * MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
+ * GNU General Public License for more details.
*
- * Most of PCM playback & capture is done through interrupt. When harmony needs
- * a new buffer to put recorded data or read played PCM, it sends an interrupt.
- * Bits 2 and 10 of DSTATUS register are '1' when harmony needs respectively
- * a new page for recording and playing.
- * 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
- * that we always need to provide adresses of playback and capture data, even
- * when this is not needed. That's why we statically alloc one graveyard
- * buffer (to put recorded data in play-only mode) and a silence buffer.
- *
- * Bitrate, number of channels and data format are controlled with
- * the CNTL register.
+ * You should have received a copy of the GNU General Public License
+ * along with this program; if not, write to the Free Software
+ * Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
*
- * Mixer work is done through one register (GAINCTL). Only input gain,
- * output attenuation and general attenuation control is provided. There is
- * also controls for enabling/disabling internal speaker and line
- * input.
+ * Notes:
+ * - graveyard and silence buffers last for lifetime of
+ * the driver. playback and capture buffers are allocated
+ * per _open()/_close().
+ *
+ * TODO:
*
- * Buffers used by this driver are all DMA consistent.
