9034ff1169 ALSA: emu10k1: clean up driver status comments
Empty BUGS and TODO sections don't really help anyone, so remove them.

Version information is chronically outdated, and not really useful in a
git world anyway, so remove it as well.

Also remove duplicated (and outdated, of course) status section from
p16v.h (the one in p16v.c is in better shape).

e73b597e63 ALSA: emu10k1: query rate of external clock sources on E-MU cards
The value isn't used yet; the subsequent commits will do that.

This ignores the existence of rates above 48 kHz, which is fine, as the
hardware will just switch to the fallback clock source when fed with a
rate which is incompatible with the base clock multiplier, which
currently is always x1.

The sample rate display in /proc spdif-in is adjusted to reflect our
understanding of the input rates.

This is tested only with an 0404b card without sync card, so there is a
lot of room for improvement.

11ee59bdac ALSA: emu10k1: add synchronized start of multi-channel playback
We use independent voices for the channels, so we need to make an effort
to ensure that they are actually in sync.

The hardware doesn't provide atomicity, so we may need to retry a few
times, due to NMIs, PCI contention, and the wrong phase of the moon.

Solution inspired by kX-project.

94dabafea0 ALSA: emu10k1: cleanup envelope register init
We (rightfully) don't enable the envelope engine for PCM voices, so any
related setup is entirely pointless - the EMU8K documentation makes that
very clear, and the fact that the various open drivers all use different
values to no observable detriment pretty much confirms it.

The remaining initializations are regrouped for clarity.

6fb861bb3c ALSA: emu10k1: fix snd_emu1010_fpga_read() input masking for rev2 cards
Unlike the Alice2 chips used on 1st generation E-MU cards, the
Tina/Tina2 chips used on the 2nd gen cards have only six GPIN pins,
which means that we need to use a smaller mask. Failure to do so would
falsify the read data if the FPGA tried to raise an IRQ right at that
moment. This wasn't a problem so far, as we didn't actually enable FPGA
IRQs, but that's going to change soon.

a1c87c0b27 ALSA: emu10k1: fix access to Audigy GPIO port
As the register definition clearly states, this is a 16-bit register,
yet we did all accesses as 32-bit. The writes in particular would have
the potential to clear the TIMER register (depending on how the bus/card
actually handles the too long writes).

This commit also introduces a separate define A_GPIO which aliases
A_IOCFG, which better reflects the distinct usage on E-MU cards.
This is done in the same commit to keep the churn down, as we're
touching all involved lines anyway.
