[media] v4l: Renesas R-Car VSP1 driver The VSP1 is a video processing engine that includes a blender, scalers, filters and statistics computation. Configurable data path routing logic allows ordering the internal blocks in a flexible way. Due to the configurable nature of the pipeline the driver implements the media controller API and doesn't use the V4L2 mem-to-mem framework, even though the device usually operates in memory to memory mode. Only the read pixel formatters, up/down scalers, write pixel formatters and LCDC interface are supported at this stage.

[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_config If a subdevice pad op is called from a bridge driver, then there is no v4l2_subdev_fh struct that can be passed to the subdevice. This made it hard to use such subdevs from a bridge driver. This patch replaces the v4l2_subdev_fh pointer by a v4l2_subdev_pad_config pointer in the pad ops. This allows bridge drivers to use the various try_ pad ops by creating a v4l2_subdev_pad_config struct and passing it along to the pad op. The v4l2_subdev_get_try_* macros had to be changed because of this, so I also took the opportunity to use the full name of the v4l2_subdev_get_try_* functions in the __V4L2_SUBDEV_MK_GET_TRY macro arguments: if you now do 'git grep v4l2_subdev_get_try_format' you will actually find the header where it is defined. One remark regarding the drivers/staging/media/davinci_vpfe patches: the *_init_formats() functions assumed that fh could be NULL. However, that's not true for this driver, it's always set. This is almost certainly a copy and paste from the omap3isp driver. I've updated the code to reflect the fact that fh is never NULL.
