I did not have any luck getting mcasp working on am437x-sk-evm. After applying " drm/omap: fix bus_flags for panel-dpi" LCD works again. But modprobe of snd-soc-davinci-mcasp and snd-soc-tlv320aic3x still does not show anything with aplay -l. Do I need some other patch or codec driver? Regards, Tony
