Subject: [PATCH] of: property: make #.*-cells optional for simple props
|
|
|
|
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.
