From ff24fed10ba414d19579e26e60b126fad2f2bb07 Mon Sep 17 00:00:00 2001 From: Michael Walle Date: Mon, 6 Feb 2023 13:43:44 +0000 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.
