[PATCH v11 17/32] rcar-vin: move media bus configuration to struct rvin_info

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Bus configuration will once the driver is extended to support Gen3
contain information not specific to only the directly connected parallel
subdevice. Move it to struct rvin_dev to show it's not always coupled
to the parallel subdevice.
