From a quick look at the code, I doubt this is really a build dependency.

In the spirit of this patch, adding entries for other tegra platforms would make
sense.ÂWould you prefer that we leave out the dependency from SND_SOC_TEGRA30_*
and only select the right I2S driver to use in each codec driver?

If not, we'd have to list all relevant platforms both in the I2S/AHUB drivers
and in each codec's rules (which is not necessarily and issue, but there's no
need to have artificial platform dependencies).

What do you think?
