Subject: [PATCH 04/13] drivers: Add generic helper to match by of_node
Date: Wed, 5 Jun 2019 16:13:41 +0100 [thread overview]
Message-ID: <1559747630-28065-5-git-send-email-suzuki.poulose@arm.com> (raw)
In-Reply-To: <1559747630-28065-1-git-send-email-suzuki.poulose@arm.com>
Add a helper to match device by the of_node. This will be later used
to provide generic lookup functions by of_node.
