From 94d964e58ad6ba907c4169be99267ef517796614 Mon Sep 17 00:00:00 2001 From: Laurent Pinchart Date: Mon, 3 Jan 2022 17:24:10 +0100 Subject: [PATCH] media: v4l2-fwnode: Move bus config structure to v4l2_mediabus.h To prepare for usage of the v4l2_fwnode_bus_* data structures to describe bus configuration in the subdev .get_mbus_config() operation, rename the structures with a v4l2_mbus_config_ prefix instead of v4l2_fwnode_bus_, and move them to v4l2_mediabus.h.
