Thus: half of the registers need to be shifted and half of them need to stay the same as in previous version of SAI. I'm not seeing yet a neater approach. Lucas idea would somehow work if regmap will allow some sort of translation function applied over registers before being accessed. Maybe Mark has some clues here? thanks, daniel. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
