Subject: media: v4l: omap3isp: Get the parallel bus type from DT
Author: Laurent Pinchart <laurent.pinchart+rene...@ideasonboard.com>
Date: Tue Jul 18 11:51:35 2017 -0400
The OMAP3 ISP supports both external and embedded BT.656 synchronization
for parallel buses. It currently gets the bus type information from the
source subdev through the .g_mbus_config() operation, but should instead
get it from DT as that's the authoritative source of bus configuration
information.
