I agree - as I say, I do think supporting suppression of the display of irrelevant/nonexistant registers would be a win. > Looking back soc-core.c again, the primary problem is that > codec_reg_show() assumes that the continuous register table beginning > from 0.

There are two issues: - I don't like pushing the entire file format into the codec driver; it feels wrong since it increases the amount of non-shared code. - Doing that prevents reuse of any part of the information elsewhere. For example, if we were to display a register value anywhere else a different interface would be required to allow codecs to override the display there. I know there are people who'd love to see things like more detailed register/control mapping information. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
