4 Subject: [PATCH] of: property: make #.*-cells optional for simple props
5
6 Sometimes, future bindings for phandles will get additional arguments.
7 Thus the target node of the phandle will need a new #.*-cells property.
8 To be backwards compatible, this needs to be optional.
9
10 Prepare the DEFINE_SIMPLE_PROPS() to handle the cells name as optional.
