Upon further inspection, yes changing existing boards can break userspace applications as some procfs entries are enumerated with the name of the soundcard. So updating AM62x is out of the question. I am in favor of maintaining naming consistency with this board. Devarsh, I notice the current scheme is not entirely opaque, as the pcm device enumerates both the cpu & codec driver names: root@am62xx-evm:~# aplay -L null Discard all samples (playback) or generate zero samples (capture) default:CARD=AM62xSKEVM AM62x-SKEVM, davinci-mcasp.0-tlv320aic3x-hifi tlv320aic3x-hifi-0 Default Audio Device sysdefault:CARD=AM62xSKEVM AM62x-SKEVM, davinci-mcasp.0-tlv320aic3x-hifi tlv320aic3x-hifi-0 Default Audio Device > If not, cleanup in a later series is fine, but please make sure to > follow through this week - with this patch following the convention of > choice. > Please feel free to pull the current series, if no further comments. > -- > Regards, > Nishanth Menon > Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D -- Thanks, Jai GPG Fingerprint: 4DE0 D818 E5D5 75E8 D45A AFC5 43DE 91F9 249A 7145
