This is unfortunate because the register settings contains invalid bit combinations marked as "N/A". For userspace it doesn't make much sense to be able to set these just to see that the driver responds with "Please make sure you select a valid quality." in the kernel log. Work around this by adding get/set functions for the quality setting.
