This is a list of trivial i2c devices that have simple device tree
bindings, consisting only of a compatible field, an address and
-possibly an interrupt line.
+possibly an interrupt line. The compatible field is used to lookup the
+modalias of the driver which will handle the device. The compatible
+string may begin with a manufacturer prefix (separated from the
+modalias by a comma) which will be stripped off during lookup.
This part of the patch described Linux-specific behaviour, whereas DT
bindings should be OS-agnostic.
I see your point but it would be nice to have language like this
somewhere. One of the biggest challenges in diving in to writing a
devicetree is figuring out details like this.
BTW, you didn't CC the DT binding maintainers.
Very true. Fixed.
