examples:
The port sample interval was always 16-bit, split into low and high bytes. This split was unnecessary, although harmless for older devices because all of them used only lower byte (so values < 0xff). With support for Soundwire controller on Qualcomm SM8550 and its devices, both bytes will be used, thus add a new 'qcom,ports-sinterval' property to allow 16-bit sample intervals.
