/* * sound/opl3sa2.c * * A low level driver for Yamaha OPL3-SA2 and SA3 cards. * NOTE: All traces of the name OPL3-SAx have now (December 2000) been * removed from the driver code, as an email exchange with Yamaha * provided the information that the YMF-719 is indeed just a * re-badged 715. * * Copyright 1998-2001 Scott Murray * * Originally based on the CS4232 driver (in cs4232.c) by Hannu Savolainen * and others. Now incorporates code/ideas from pss.c, also by Hannu * Savolainen.

Lahaie Changed probing / attach code order * Scott Murray Added mixer support (Dec 03, 1998) * Scott Murray Changed detection code to be more forgiving, * added force option as last resort, * fixed ioctl return values. (Dec 30, 1998) * Scott Murray Simpler detection code should work all the time now * (with thanks to Ben Hutchings for the heuristic), * removed now unnecessary force option. (Jan 5, 1999) * Christoph Hellwig Adapted to module_init/module_exit (Mar 4, 2000) * Scott Murray Reworked SA2 versus SA3 mixer code, updated chipset * version detection code (again!). (Dec 5, 2000) * Scott Murray Adjusted master volume mixer scaling. (Dec 6, 2000) * Scott Murray Based on a patch by Joel Yliluoma (aka Bisqwit), * integrated wide mixer and adjusted mic, bass, treble * scaling. (Dec 6, 2000) * Scott Murray Based on a patch by Peter Englmaier, integrated * ymode and loopback options. (Dec 6, 2000) * Scott Murray Inspired by a patch by Peter Englmaier, and based on * what ALSA does, added initialization code for the * default DMA and IRQ settings. (Dec 6, 2000) * Scott Murray Added some more checks to the card detection code, * based on what ALSA does. (Dec 12, 2000) * Scott Murray Inspired by similar patches from John Fremlin, * Jim Radford, Mike Rolig, and Ingmar Steen, added 2.4 * ISA PnP API support, mainly based on bits from * sb_card.c and awe_wave.c. (Dec 12, 2000) * Scott Murray Some small cleanups to the init code output. * (Jan 7, 2001) * Zwane Mwaikambo Added PM support. (Dec 4 2001) * * Adam Belay Converted driver to new PnP Layer (Oct 12, 2002) * Zwane Mwaikambo Code, data structure cleanups. (Feb 15 2002) * Zwane Mwaikambo Free resources during auxiliary device probe * failures (Apr 29 2002) * */ #include #include #include #include #include #include #include "sound_config.h" #include "ad1848.h" #include "mpu401.h" #define OPL3SA2_MODULE_NAME "opl3sa2" #define PFX OPL3SA2_MODULE_NAME ": " /* Useful control port indexes: */ #define OPL3SA2_PM 0x01 #define OPL3SA2_SYS_CTRL 0x02 #define OPL3SA2_IRQ_CONFIG 0x03 #define OPL3SA2_DMA_CONFIG 0x06 #define OPL3SA2_MASTER_LEFT 0x07 #define OPL3SA2_MASTER_RIGHT 0x08 #define OPL3SA2_MIC 0x09 #define OPL3SA2_MISC 0x0A #define OPL3SA3_WIDE 0x14 #define OPL3SA3_BASS 0x15 #define OPL3SA3_TREBLE 0x16 /* Useful constants: */ #define DEFAULT_VOLUME 50 #define DEFAULT_MIC 50 #define DEFAULT_TIMBRE 0 /* Power saving modes */ #define OPL3SA2_PM_MODE0 0x00 #define OPL3SA2_PM_MODE1 0x04 /* PSV */ #define OPL3SA2_PM_MODE2 0x05 /* PSV | PDX */ #define OPL3SA2_PM_MODE3 0x27 /* ADOWN | PSV | PDN | PDX */ /* For checking against what the card returns: */ #define VERSION_UNKNOWN 0 #define VERSION_YMF711 1 #define VERSION_YMF715 2 #define VERSION_YMF715B 3 #define VERSION_YMF715E 4 /* also assuming that anything > 4 but <= 7 is a 715E */ /* Chipset type constants for use below */ #define CHIPSET_UNKNOWN -1 #define CHIPSET_OPL3SA2 0 #define CHIPSET_OPL3SA3 1 static const char *CHIPSET_TABLE[] = {"OPL3-SA2", "OPL3-SA3"}; #ifdef CONFIG_PNP #define OPL3SA2_CARDS_MAX 4 #else #define OPL3SA2_CARDS_MAX 1 #endif /* This should be pretty obvious */ static int opl3sa2_cards_num; typedef struct { /* device resources */ unsigned short cfg_port; struct address_info cfg; struct address_info cfg_mss; struct address_info cfg_mpu; #ifdef CONFIG_PNP /* PnP Stuff */ struct pnp_dev* pdev; int activated; /* Whether said devices have been activated */ #endif #ifdef CONFIG_PM unsigned int in_suspend; struct pm_dev *pmdev; #endif unsigned int card; int chipset; /* What's my version(s)? */ char *chipset_name; /* mixer data */ int mixer; unsigned int volume_l; unsigned int volume_r; unsigned int mic; unsigned int bass_l; unsigned int bass_r; unsigned int treble_l; unsigned int treble_r; unsigned int wide_l; unsigned int wide_r; } opl3sa2_state_t; static opl3sa2_state_t opl3sa2_state[OPL3SA2_CARDS_MAX]; /* Our parameters */ static int __initdata io = -1; static int __initdata mss_io = -1; static int __initdata mpu_io = -1; static int __initdata irq = -1; static int __initdata dma = -1; static int __initdata dma2 = -1; static int __initdata ymode = -1; static int __initdata loopback = -1; #ifdef CONFIG_PNP /* PnP specific parameters */ static int __initdata isapnp = 1; static int __initdata multiple = 1; /* Whether said devices have been activated */ static int opl3sa2_activated[OPL3SA2_CARDS_MAX]; #else static int __initdata isapnp; /* = 0 */ static int __initdata multiple; /* = 0 */ #endif MODULE_DESCRIPTION("Module for OPL3-SA2 and SA3 sound cards (uses AD1848 MSS driver)."); MODULE_AUTHOR("Scott Murray "); MODULE_LICENSE("GPL"); module_param(io, int, 0); MODULE_PARM_DESC(io, "Set I/O base of OPL3-SA2 or SA3 card (usually 0x370.
