Does this need to be bus-frequency? It's always called MCLK in all of the literature.

In my case the MCLK comes from a chip on the i2c bus that is programmable How would that be encoded?.

Grah! If there's one obvious frequency for a node, it should always be "clock-frequency". This bus-frequency nonsense seems to be a disease that started as a secondary frequency in Freescale CPU nodes, and has escaped to all sorts of other places.
