[alsa-devel] Correct i2s implementation for s3c2416
Hi,
I'm trying to make sound work on a s3c2416 based device and am quite confused about the underlying I2S stuff as it seems there are 3 different I2S implementations for samsung SoCs.
The i2s.c and .h seem to be made for the s3c64xx and up (according to the initial commit message). This leaves the s3c-i2s-v2+s3c2412_i2s combination and s3c24xx-iis.
Documentation on this seems a bit sparse and I'm still taking first steps in kernel-development at all - so I would be really thankfull for a pointer in the right direction.
Thanks Heiko

Yes, that shares the common core of S3C64XX and up.
This leaves the s3c-i2s-v2+s3c2412_i2s combination and s3c24xx-iis.
IIRC, 2416 and 64xx have similar (exactly same?) I2S blocks. So, you need to simply follow what is being done for I2S on SMDK6410 as an example.

thanks.
I think this suggestion saved me alot of hours and grey hair :-)
From my inexperienced viewpoint the 2416 seemed more similar to the 2412. Therefore I started meddling with this i2s driver. But with your pointer even the s3c6400-remenants in the vendor kernels [1] we posses make sense.
So again thanks Heiko
