Subject: [PATCH 1/2] of: overlay: do not parse phandles as properties
Date: Wed, 13 Jan 2021 08:57:56 +0100	[thread overview]
Message-ID: <20210113075757.21478-1-r.czerwinski@pengutronix.de> (raw)

Instead of handling phandles as properties, assign them directly as a
handle to the node. This allows phandles within nodes inside the device
tree overlays to be handled correctly.
