This is the first attempt at extending soc-camera with Media Controller / pad-level APIs. Yes, I know, that Laurent wasn't quite happy with "V4L: add convenience macros to the subdevice / Media Controller API," maybe we'll remove it eventually, but so far my patches use it, so, I kept it for now. The general idea has been described in http://article.gmane.org/gmane.linux.drivers.video-input-infrastructure/38083 In short: soc-camera implements a media controller device and two entities per camera host (bridge) instance, linked statically to each other and to the client. The host driver gets a chance to implement "local" only configuration, as opposed to the standard soc-camera way of propagating the configuration up the pipeline to the client (sensor / decoder) driver. An example implementation is provided for sh_mobile_ceu_camera and two sensor drivers. The whole machinery gets activated if the soc-camera core finds a client driver, that implements pad operations. In that case both the "standard" (V4L2) and the "new" (MC) ways of addressing the driver become available. I.e., it is possible to run both standard V4L2 applications and MC-aware ones. Of course, applies on top of git://linuxtv.org/gliakhovetski/v4l-dvb.git for-3.2 Deepthy: this is what I told you about in http://article.gmane.org/gmane.linux.ports.arm.omap/64847 it just took me a bit longer, than I thought.
