Yes this is very much similar to the pinctrl.yaml that defines a 
top-level object that can then be used by different devices and those 
devices can then define the properties they need. So the examples for 
I2C and MMC really demonstrate how this would be used in the subsequent 
patches. Obviously we are open to any ideas on how if there are better 
or preferred ways to do this.
