By default, getting a property will fall through to the “lower layer” (the device tree), unless a property has been explicitly set by software, in which case its value is interposed.  There is a separate set of functions that allow software to go directly to the device tree, if needed, using the device’s devhandle directly.

Thanks for the constructive feedback I have received so far!  I’ve incorporated several suggestions, and have also tweaked a few things to handle situations I encountered when converting code using platform-specific functions to the general functions.  An updated diff is here:
