2015-03-23[media] v4l2-subdev: remove enum_framesizes/intervalsHans Verkuil1-2/+0
The video and pad ops are duplicates, so get rid of the more limited video op. The whole point of the subdev API is to allow reuse of subdev drivers by bridge drivers. Having duplicate ops makes that much harder. We should never have allowed duplicate ops in the first place. A lesson for the future.

2015-03-23[media] v4l2-subdev.h: add 'which' field for the enum structsHans Verkuil1-3/+9
While all other pad ops allow you to select whether to use the 'try' or the 'active' formats, the enum ops didn't have that option and always used 'try'. However, this will fail if a simple (e.g. PCI) bridge driver wants to use the enum pad op of a subdev that's also used in a complex platform driver like the omap3. Such a bridge driver generally wants to enum formats based on the active format. So add a new 'which' field to these structs. Note that V4L2_SUBDEV_FORMAT_TRY is 0, so the default remains TRY (applications need to set reserved to 0).

2015-03-23[media] v4l2-subdev: replace v4l2_subdev_fh by v4l2_subdev_pad_configHans Verkuil48-797/+813
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.
