Subject: [RFC 01/10] property: add fwnode_match_node()
Date: Mon, 21 Feb 2022 17:26:43 +0100 [thread overview]
Message-ID: <20220221162652.103834-2-clement.leger@bootlin.com> (raw)
In-Reply-To: <20220221162652.103834-1-clement.leger@bootlin.com>
Add a function equivalent to of_match_node() which is usable for fwnode
support. Matching is based on the compatible property and it returns
the best matches for the node according to the compatible list
ordering.
