Hello, We (National Semi) have developed ALSA based audio drivers for our Audio subsystem. Could you please let me know the process to submit and include as part of ALSA project.
The ALSA audio driver version info as follows:
- Linux - 2.6.24 base
- Andorid- 2.1 base
Is this based on ASoC? If not, I recommend you to port the code to ASoC, thus it's the standard for embedded devices. If you have any questions, just post to alsa-devel ML.
thanks,
Takashi

OK, then just post your patches to alsa-devel ML, Cc'ed to ASoC maintainers (Liam Girdwood lrg@slimlogic.co.uk and Mark Brown broonie@opensource.wolfsonmicro.com).
But I guess there have been quite many changes in ASoC core (e.g. multi-core support) that are no longer compatible with 2.6.24-based code. These have to be fixed, of course, before merging.
It's up to you -- you can first pot the original patch and ask some hints for forward-porting, or first start reading the latest ASoC API changes, do port your driver then post the revised patch.
thanks,
Takashi

Hi Takashi,
OK. I will submit the patches for National's (NSC) LM49352 and LM49350 audio cards (with older version of ALSA and Linux 2.6.24 tested). And request for the forward porting guidelines.
Thanks Swami

If you are trying to submit your new ASoC driver, you may work based on Mr. Mark Brown's ASoC git repository (git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound-2.6.git). And also, if your driver works on Samsung 6410 target, 'sound/soc/samsung/smdk_wm8580.c' and 'sound/soc/samsung/smdk_wm9713.c' on 'for-2.6.39' (or 'for-next') branch will give you some hints. ;)
Have fun, claude
