From 4f4145c9fee8c7a445dbbbadceccce5391e6b287 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Tue, 6 Dec 2022 21:07:22 +0100 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.
