[PATCH v5 03/21] of: property: make #.*-cells optional for simple props
From: Michael Walle
Date: Tue Dec 06 2022 - 15:08:03 EST
Sometimes, future bindings for phandles will get additional arguments.
Thus the target node of the phandle will need a new #.*-cells property.
To be backwards compatible, this needs to be optional.
Prepare the DEFINE_SIMPLE_PROPS() to handle the cells name as optional.
