In addition, add constraint to limit the max value of rate because the rate higher than 96000(172000, 192000) is not stable either.What is the source of these restrictions - are they due to the component devices? If they are then the component devices ought to be setting suitable constraints themselves.
I'm not sure why it happened. But I guess it is not the issues on those components because they work normally on other machine drivers. Because this driver is old and lacks maintenance, I think we can just filter some unstable formats. Actually, those formats are very rarely used as well. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
