OSS has very little if any useful life in it left for MIPS, at least from
my perspective. So I propose to remove the Au1550 driver - there is an
ALSA replacement for it available.
Anybody against it? Are there still any remaining features or platforms
that are only supported by the OSS driver?
The OSS code is so backwards that I'd like to retire the possible remaining
MIPS users and then make OSS unavailable in Kconfig for MIPS.

Even two variants available: one in ASoC driver and one in old ALSA
driver.

The current ASoC code can replace sound/oss/au1550_ac97.c,
but sound/mips/au1x00.c is for different (earlier) chips. I wrote an ASoC
variant of this a long time ago, but I can't test it on real hardware.

My immediate interest is to kill off sounds/oss/ on MIPS because
sound/oss/soundcard.c is fairly ISA centric and does not build for some
some MIPS systems with only half-arsed ISA support, that is no DMA support.
Manuel, I got a DBAu1250 board here and maybe I can find a DBAu1500
Zinfandel board under some dusty hardware pile; would that be suitable for
testing your work?

Yes, the db1500 would be perfect.
