From 91c7953005247c9563408bbdbf35e27de33e6ec3 Mon Sep 17 00:00:00 2001 From: Guennadi Liakhovetski Date: Fri, 1 Jul 2011 14:31:17 -0300 Subject: [media] V4L: add media bus configuration subdev operations Add media bus configuration types and two subdev operations to get supported mediabus configurations and to set a specific configuration. Subdevs can support several configurations, e.g., they can send video data on 1 or several lanes, can be configured to use a specific CSI-2 channel, in such cases subdevice drivers return bitmasks with all respective bits set. When a set-configuration operation is called, it has to specify a non-ambiguous configuration.
