Subject: [PATCH v4 05/10] dt-bindings: i3c: Add macros to help fill I3C/I2C device's reg property
Date: Fri, 30 Mar 2018 09:47:46 +0200 [thread overview]
Message-ID: <20180330074751.25987-6-boris.brezillon@bootlin.com> (raw)
In-Reply-To: <20180330074751.25987-1-boris.brezillon@bootlin.com>
The reg property of devices connected to an I3C bus have 3 cells, and
filling them manually is not trivial. Provides macros to help doing
that.
