[PATCH RFC 3/3] ARM: da850/omap-l138: vpif capture convert to asynchronously register of subdev

From: Lad, Prabhakar
Date: Wed Jan 09 2013 - 08:42:03 EST


Register the tvp514x decoder devices directly in board platform
data instead of letting the vpif capture driver register them at
their run-time. This uses the V4L2 asynchronous subdevice probing capability.
