[PATCH 0/2] Updates for Atmel SSC DAI
This patch set includes two updates for the Atmel SSC DAI driver: - Address the limitation with the S24_LE format. - Add stream names for DPCM and future use-cases.
Codrin Ciubotariu (2): ASoC: atmel: atmel_ssc_dai: Add stream names ASoC: atmel: atmel_ssc_dai: Drop S24_LE support due to single channel limitation

Drop S24_LE format because it is not supported if more than 2 channels (of TDM slots) are used. This limitation makes it impractical for use cases requiring more than 2 TDM slots, leading to potential issues in multi-channel configurations.

I believe this requires a comment. Else someone may add it back later on.
It is unclear to me. Would it be good to send v2 with this update?

Yes, please send a new version. My point is that it is explained in the commit log. This is fine when you are adding something because then people will easily use git blame and find the commit and log. However, because you are removing code, it is not obvious there is a reason why it isn't there;
