Subject: [RFCv4 3/7] dt-bindings: devfreq: imx: Describe interconnect properties
Date: Fri, 23 Aug 2019 17:36:56 +0300 [thread overview]
Message-ID: <3f27038292c09c8bf07a086eac759132c100aedb.1566570260.git.leonard.crestez@nxp.com> (raw)
In-Reply-To: <cover.1566570260.git.leonard.crestez@nxp.com>
In-Reply-To: <cover.1566570260.git.leonard.crestez@nxp.com>
The interconnect-node-id property is parsed by the imx interconnect
driver to find nodes on which frequencies can be adjusted.
Add #interconnect-cells so that device drivers can request paths from
bus nodes instead of requiring a separate "virtual" node to represent
the interconnect itself.
