Add lane_polarities field to struct v4l2_of_bus_mipi_csi2 and write the contents of the lane-polarities property to it. The field tells the polarity of the physical lanes starting from the first one. Any unused lanes are ignored, i.e. only the polarity of the used lanes is specified. Also rework reading the "data-lanes" property a little.

Make omap3isp configuration data structures more suitable for consumption by the DT by separating the I2C bus information of all the sub-devices in a group and the ISP bus information from each other. The ISP bus information is made a pointer instead of being directly embedded in the struct. In the case of the DT only the sensor specific information on the ISP bus configuration is retained. The structs are renamed to reflect that. After this change the structs needed to describe device configuration can be allocated and accessed separately without those needed only in the case of platform data. The platform data related structs can be later removed once the support for platform data can be removed.

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.

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.

The handling of VIDIOC_G/S_PRIORITY is now entirely done by the V4L2 core, so we can drop the g/s_priority ioctl ops. We do have to make sure though that when S_PRIORITY is called we check that the driver used struct v4l2_fh. This check can be removed once all drivers are converted to that structure.

The previous provision for DVB media controller support were to define an ID (likely meaning the adapter number) for the DVB devnodes. This is just plain wrong. Just like V4L, DVB devices (and any other device node)) are uniquely identified via a (major, minor) tuple. This is enough to uniquely identify a devnode, no matter what API it implements. So, before we go too far, let's mark the old v4l, fb, dvb and alsa "devnode" info as deprecated, and just call it as "dev". We can latter add fields specific to each API if needed. As we don't want to break compilation on already existing apps, let's just keep the old definitions as-is, adding a note that those are deprecated at media-entity.h.

The old debug field is renamed to dev_debug to ensure that existing drivers (including out-of-tree drivers) that try to use the old name will no longer compile. A comment has also been added that makes it explicit that drivers shouldn't use this field. Additional bits have been added to the debug flag to be more fine-grained when debugging, especially when dealing with streaming ioctls and read, write and poll. You want to enable those explicitly to prevent flooding the log when streaming unless you actually want to do that.

The recent conversion of saa7134 to vb2 unconvered a poll() bug that broke the teletext applications alevt and mtt. These applications expect that calling poll() without having called VIDIOC_STREAMON will cause poll() to return POLLERR. That did not happen in vb2. This patch fixes that behavior. It also fixes what should happen when poll() is called when STREAMON is called but no buffers have been queued. In that case poll() will also return POLLERR, but only for capture queues since output queues will always return POLLOUT anyway in that situation. This brings the vb2 behavior in line with the old videobuf behavior.
