- *	Intel i810 and friends ICH driver for Linux
- *	Alan Cox <alan@redhat.com>
- *
- *  Built from:
- *	Low level code:  Zach Brown (original nonworking i810 OSS driver)
- *			 Jaroslav Kysela <perex@suse.cz> (working ALSA driver)
- *
- *	Framework: Thomas Sailer <sailer@ife.ee.ethz.ch>
- *	Extended by: Zach Brown <zab@redhat.com>  
- *			and others..
- *
- *  Hardware Provided By:
- *	Analog Devices (A major AC97 codec maker)
- *	Intel Corp  (you've probably heard of them already)
- *
- *  AC97 clues and assistance provided by
- *	Analog Devices

- *
- *	Intel 810 theory of operation
- *
- *	The chipset provides three DMA channels that talk to an AC97
- *	CODEC (AC97 is a digital/analog mixer standard). At its simplest
- *	you get 48Khz audio with basic volume and mixer controls. At the
- *	best you get rate adaption in the codec. We set the card up so
- *	that we never take completion interrupts but instead keep the card
- *	chasing its tail around a ring buffer. This is needed for mmap
- *	mode audio and happens to work rather well for non-mmap modes too.
- *
- *	The board has one output channel for PCM audio (supported) and
- *	a stereo line in and mono microphone input. Again these are normally
- *	locked to 48Khz only. Right now recording is not finished.
- *
- *	There is no midi support, no synth support. Use timidity. To get
- *	esd working you need to use esd -r 48000 as it won't probe 48KHz
- *	by default. mpg123 can't handle 48Khz only audio so use xmms.
- *
- *	Fix The Sound On Dell
- *
- *	Not everyone uses 48KHz. We know of no way to detect this reliably
- *	and certainly not to get the right data. If your i810 audio sounds
- *	stupid you may need to investigate other speeds. According to Analog
- *	they tend to use a 14.318MHz clock which gives you a base rate of
- *	41194Hz.
- *
- *	This is available via the 'ftsodell=1' option. 
- *
- *	If you need to force a specific rate set the clocking= option
- *
- *	This driver is cursed. (Ben LaHaise)
- *
- *  ICH 3 caveats
- *	Intel errata #7 for ICH3 IO. We need to disable SMI stuff
- *	when codec probing. [Not Yet Done]
- *
- *  ICH 4 caveats
- *
- *	The ICH4 has the feature, that the codec ID doesn't have to be 
- *	congruent with the IO connection.
- * 
- *	Therefore, from driver version 0.23 on, there is a "codec ID" <->
- *	"IO register base offset" mapping (card->ac97_id_map) field.
- *
