And worse: > how should consumers even know that the driver supports phase shifts? I'm aware that we're a long way from being able to use this. The clean approach would be to get the offset from the device tree in the same way as the period. And in the meantime I agree that introducing a flag that allows to shift the active part in the period is a sane idea. So I suggest we concentrate on getting the details in the corresponding discussion straight.
