Subject: [PATCH v4 03/20] of: property: make #.*-cells optional for simple props
Date: Wed, 23 Nov 2022 19:01:34 +0100 [thread overview]
Message-ID: <20221123180151.2160033-4-michael@walle.cc> (raw)
In-Reply-To: <20221123180151.2160033-1-michael@walle.cc>
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.
