This patch adds support for SNDRV_PCM_RATE_KNOT so that users can open stream at these rates. As part of this we should always set constraints in arizona_startup, currently we only set the constraints if we already have a clock to limit rates to that family of sample rates. This patch updates this to set a constraint of all rates supported by the chip if we do not already know which family of rates to limit to. Finally we also reduce the list of rates supported in the constraints to only include those that are supported on current parts. Signed-off-by: Charles Keepax --- Thanks, for the pointer there Lars, sorry for missing what you were talking about the first time. It does indeed look much nicer this way. Changes since v1: - Use the mask field in the constaint list as suggested by Lars.
