- * tabs should be 4 spaces, in vi(m): set tabstop=4
- *
- * TODO: consistency speed calculations!!
- * cleanup!
- * ????: Did I break MIDI support?
- *
- * History:
- *
- * Rolf Fokkens (Dec 20 1998): ES188x recording level support on a per
- * fokkensr@vertis.nl input basis.
- * (Dec 24 1998): Recognition of ES1788, ES1887, ES1888,
- * ES1868, ES1869 and ES1878. Could be used for
- * specific handling in the future. All except
- * ES1887 and ES1888 and ES688 are handled like
- * ES1688.
- * (Dec 27 1998): RECLEV for all (?) ES1688+ chips. ES188x now
- * have the "Dec 20" support + RECLEV
- * (Jan 2 1999): Preparation for Full Duplex. This means
- * Audio 2 is now used for playback when dma16
- * is specified. The next step would be to use
- * Audio 1 and Audio 2 at the same time.
- * (Jan 9 1999): Put all ESS stuff into sb_ess.[ch], this
- * includes both the ESS stuff that has been in
- * sb_*[ch] before I touched it and the ESS support
- * I added later
- * (Jan 23 1999): Full Duplex seems to work. I wrote a small
- * test proggy which works OK. Haven't found
- * any applications to test it though. So why did
- * I bother to create it anyway?? :) Just for
- * fun.
- * (May 2 1999): I tried to be too smart by "introducing"
- * ess_calc_best_speed (). The idea was that two
- * dividers could be used to setup a samplerate,
- * ess_calc_best_speed () would choose the best.
- * This works for playback, but results in
- * recording problems for high samplerates. I
- * fixed this by removing ess_calc_best_speed ()
- * and just doing what the documentation says.
- * Andy Sloane (Jun 4 1999): Stole some code from ALSA to fix the playback
- * andy@guildsoftware.com speed on ES1869, ES1879, ES1887, and ES1888.
- * 1879's were previously ignored by this driver;
- * added (untested) support for those.
- * Cvetan Ivanov (Oct 27 1999): Fixed ess_dsp_init to call ess_set_dma_hw for
- * zezo@inet.bg _ALL_ ESS models, not only ES1887
- *
- * This files contains ESS chip specifics. It's based on the existing ESS
- * handling as it resided in sb_common.c, sb_mixer.c and sb_audio.c. This
- * file adds features like:
- * - Chip Identification (as shown in /proc/sound)
- * - RECLEV support for ES1688 and later
- * - 6 bits playback level support chips later than ES1688
- * - Recording level support on a per-device basis for ES1887
- * - Full-Duplex for ES1887
- *
- * Full duplex is enabled by specifying dma16. While the normal dma must
- * be one of 0, 1 or 3, dma16 can be one of 0, 1, 3 or 5. DMA 5 is a 16 bit
- * DMA channel, while the others are 8 bit..
- *
- * ESS detection isn't full proof (yet). If it fails an additional module
- * parameter esstype can be specified to be one of the following:
- * -1, 0, 688, 1688, 1868, 1869, 1788, 1887, 1888
- * -1 means: mimic 2.0 behaviour,
- * 0 means: auto detect.
- * others: explicitly specify chip
- * -1 is default, cause auto detect still doesn't work.

-/*
- * About the documentation
- *
- * I don't know if the chips all are OK, but the documentation is buggy. 'cause
- * I don't have all the cips myself, there's a lot I cannot verify. I'll try to
- * keep track of my latest insights about his here. If you have additional info,
- * please enlighten me (fokkensr@vertis.nl)!
- *
- * I had the impression that ES1688 also has 6 bit master volume control. The
- * documentation about ES1888 (rev C, october '95) claims that ES1888 has
- * the following features ES1688 doesn't have:
- * - 6 bit master volume
- * - Full Duplex
- * So ES1688 apparently doesn't have 6 bit master volume control, but the
- * ES1688 does have RECLEV control. Makes me wonder: does ES688 have it too?
- * Without RECLEV ES688 won't be much fun I guess.
- *
- * From the ES1888 (rev C, october '95) documentation I got the impression
- * that registers 0x68 to 0x6e don't exist which means: no recording volume
- * controls. To my surprise the ES888 documentation (1/14/96) claims that
- * ES888 does have these record mixer registers, but that ES1888 doesn't have
- * 0x69 and 0x6b. So the rest should be there.
- *
- * I'm trying to get ES1887 Full Duplex. Audio 2 is playback only, while Audio 2
- * is both record and playback. I think I should use Audio 2 for all playback.
- *
- * The documentation is an adventure: it's close but not fully accurate. I
- * found out that after a reset some registers are *NOT* reset, though the
- * docs say the would be. Interesting ones are 0x7f, 0x7d and 0x7a. They are
- * related to the Audio 2 channel. I also was surprised about the consequences
- * of writing 0x00 to 0x7f (which should be done by reset): The ES1887 moves
- * into ES1888 mode. This means that it claims IRQ 11, which happens to be my
- * ISDN adapter. Needless to say it no longer worked. I now understand why
- * after rebooting 0x7f already was 0x05, the value of my choice: the BIOS
- * did it.
- *
- * Oh, and this is another trap: in ES1887 docs mixer register 0x70 is
- * described as if it's exactly the same as register 0xa1. This is *NOT* true.
- * The description of 0x70 in ES1869 docs is accurate however.
- * Well, the assumption about ES1869 was wrong: register 0x70 is very much
- * like register 0xa1, except that bit 7 is always 1, whatever you want
- * it to be.
- *
- * When using audio 2 mixer register 0x72 seems te be meaningless. Only 0xa2
- * has effect.
- *
- * Software reset not being able to reset all registers is great! Especially
- * the fact that register 0x78 isn't reset is great when you wanna change back
- * to single dma operation (simplex): audio 2 is still operational, and uses
- * the same dma as audio 1: your ess changes into a funny echo machine.
- *
- * Received the news that ES1688 is detected as a ES1788. Did some thinking:
- * the ES1887 detection scheme suggests in step 2 to try if bit 3 of register
- * 0x64 can be changed. This is inaccurate, first I inverted the * check: "If
- * can be modified, it's a 1688", which lead to a correct detection
- * of my ES1887. It resulted however in bad detection of 1688 (reported by mail)
- * and 1868 (if no PnP detection first): they result in a 1788 being detected.
- * I don't have docs on 1688, but I do have docs on 1868: The documentation is
- * probably inaccurate in the fact that I should check bit 2, not bit 3. This
- * is what I do now.

-/*
- * About recognition of ESS chips
- *
- * The distinction of ES688, ES1688, ES1788, ES1887 and ES1888 is described in
- * a (preliminary ??) datasheet on ES1887. Its aim is to identify ES1887, but
- * during detection the text claims that "this chip may be ..." when a step
- * fails. This scheme is used to distinct between the above chips.
- * It appears however that some PnP chips like ES1868 are recognized as ES1788
- * by the ES1887 detection scheme. These PnP chips can be detected in another
- * way however: ES1868, ES1869 and ES1878 can be recognized (full proof I think)
- * by repeatedly reading mixer register 0x40. This is done by ess_identify in
- * sb_common.c.
- * This results in the following detection steps:
- * - distinct between ES688 and ES1688+ (as always done in this driver)
- * if ES688 we're ready
- * - try to detect ES1868, ES1869 or ES1878
- * if successful we're ready
- * - try to detect ES1888, ES1887 or ES1788
- * if successful we're ready
- * - Dunno. Must be 1688. Will do in general
- *
- * About RECLEV support:
- *
- * The existing ES1688 support didn't take care of the ES1688+ recording
- * levels very well. Whenever a device was selected (recmask) for recording
- * its recording level was loud, and it couldn't be changed. The fact that
- * internal register 0xb4 could take care of RECLEV, didn't work meaning until
- * its value was restored every time the chip was reset; this reset the
- * value of 0xb4 too. I guess that's what 4front also had (have?) trouble with.
- *
- * About ES1887 support:
- *
- * The ES1887 has separate registers to control the recording levels, for all
- * inputs. The ES1887 specific software makes these levels the same as their
- * corresponding playback levels, unless recmask says they aren't recorded. In
- * the latter case the recording volumes are 0.
- * Now recording levels of inputs can be controlled, by changing the playback
- * levels. Furthermore several devices can be recorded together (which is not
- * possible with the ES1688).
- * Besides the separate recording level control for each input, the common
- * recording level can also be controlled by RECLEV as described above.
- *
- * Not only ES1887 have this recording mixer. I know the following from the
- * documentation:
- * ES688 no
- * ES1688 no
- * ES1868 no
- * ES1869 yes
- * ES1878 no
- * ES1879 yes
- * ES1888 no/yes Contradicting documentation; most recent: yes
- * ES1946 yes This is a PCI chip; not handled by this driver
