Subject: [PATCH v3 4/9] of: property: fw_devlink: Add support for "depends-on"
Date:   Wed,  7 Dec 2022 17:24:30 +0100
Message-Id: <20221207162435.1001782-5-herve.codina@bootlin.com>
In-Reply-To: <20221207162435.1001782-1-herve.codina@bootlin.com>

The generic "depends-on" property expresses a simple functionnal
dependency. The "depends-on" consumer must be available before
the "depends-on" provider.

Handling "depends-on" as a fw_devlink matches this dependency in
a generic way.
