If you submit a patch to a new driver, it should be against the very
latest ALSA tree, which is basically based on the latest mm tree
(2.6.22-rc*-mm*) and planned to be merged into the next kernel
Is there any difference between 2.6.21 and 22 regarding SH arch
specific things? At least, there is no difference regarding the sound

If the driver is supposed to be merged to the linux kernel tree
(i.e. mature enough and tested), it can go to alsa-kernel tree. Then
alsa-driver tree will keep only other necessary stubs for external
If the driver is still in the early development stage and not intended
to be merged to the upstream kernel, we can keep it in alsa-driver

Just post the tarball. Don't forget to add a developer (e.g. me) to
Cc to make sure that the post can be checked properly.

Yeah, it's not too easy. First, we'd need to add the architecture
check and the corresponding options in configure script.
I'll take care of it.
