'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.
