Hello all,
I'm making slow progress with the sound driver. One question has been bothering me. How do I wait properly in a rtdm driver routine, i.e. I need to wait a few microseconds for a register to "settle" or for the codecs to come back from reset. This would be required in both routines that can be called from realtime as well as non-realtime tasks.
Thanks, Thomas

That's a typical job for rtdm_task_busy_sleep():
