Subject: [PATCH 10/17] pinctrl: Find controller node first
Date: Thu, 6 May 2021 11:28:54 +0200
Message-ID: <20210506092901.25461-11-s.hauer@pengutronix.de> (raw)
In-Reply-To: <20210506092901.25461-1-s.hauer@pengutronix.de>
The pinctrl controller node is the first parent node that has a compatible
property. Use that information to find the node without iterating up to
the root node.
