Newbie questions regarding ALSA drivers

Newbie questions regarding ALSA drivers

[Pharaoh .]

Hi,
I am very new to ALSA and just trying to get familier with the things, I
have
got few questions.

1. Is it true that all the OSS drivers are included only in directory
linux/sound/oss  and no where else?
2. There are arch specific folders like ARM, MIPS etc, so all the drivers in
these folders are ALSA or OSS?
3. If I write a new driver for an OMAP based board, it should go in to
linux/sound/arm/omap/ right? Or only ALSA drivers for this board should go
there?
4. I have some old OSS drivers
which were written for my board, do I need to make them ALSA drivers
to be in line with the latest trend i.e. phasing out OSS drivers?

Afaik, mostly yes. I've seen some in other places, although they were
never official.

ALSA

It could either go in linux/sound/arm or you could write a more generic
omap driver (i.e. not tightly coupled to either your board or codec) and
place it in sound/soc/omap/, this would allow your work to be used on
other boards/platforms.

Yes, I would recommend this.
