Subject: [PATCH v8 18/21] v4l: fwnode: Add convenience function for parsing common external refs
Date: Tue, 5 Sep 2017 16:05:50 +0300 [thread overview]
Message-ID: <20170905130553.1332-19-sakari.ailus@linux.intel.com> (raw)
In-Reply-To: <20170905130553.1332-1-sakari.ailus@linux.intel.com>
Add v4l2_fwnode_parse_reference_sensor_common for parsing common
sensor properties that refer to adjacent devices such as flash or lens
driver chips.
As this is an association only, there's little a regular driver needs to
know about these devices as such.
