The use of 'DTV' is very confusing since it normally refers to Digital TV e.g. DVB etc. Instead use 'DV' (Digital Video), which nicely corresponds to the DV Timings API used to configure such receivers and transmitters. We keep an alias to avoid breaking userspace applications. Since this alias is only available if __KERNEL__ is *not* defined (i.e. it is only available for userspace, not kernelspace), any drivers that use it also have to be converted to the new define. These drivers are adv7604, adv7842 and tda1997x. Signed-off-by:

Document the new struct media_v2_entity 'flags' field. Signed-off-by:
-
Hans Verkuil authored
The v2 entity structure never exposed the entity flags, which made it impossible to detect connector or default entities. It is really trivial to just expose this information, so implement this. Signed-off-by:

Document the new struct media_v2_pad 'index' field. Signed-off-by:
-
Hans Verkuil authored
The v2 pad structure never exposed the pad index, which made it impossible to call the MEDIA_IOC_SETUP_LINK ioctl, which needs that information. It is really trivial to just expose this information, so implement this. Signed-off-by:

Add support for the new (optional) 5V gpio in order to debug 5V changes. Some displays turn off CEC if the 5V is not detected, so it is useful to be able to monitor this line. Signed-off-by:

Commit 1d389714 ("[media] v4l: rcar_fdp1: add FCP dependency") fixed a compilation breakage when the optional VIDEO_RENESAS_FCP dependency is compiled as a module while the rcar_fdp1 driver is built in. As a side effect it disabled compilation on Gen2 by disallowing the valid combination ARCH_RENESAS && !VIDEO_RENESAS_FCP. Fix it by handling the dependency the same way the vsp1 driver did in commit 19994673 ("[media] vsp1: clarify FCP dependency"). Fixes: 1d389714 ("[media] v4l: rcar_fdp1: add FCP dependency") Signed-off-by:

The vb2_core_qbuf() function didn't check if q->error was set. It is checked in __buf_prepare(), but that function isn't called if the buffer was already prepared before with VIDIOC_PREPARE_BUF. So check it at the start of vb2_core_qbuf() as well. Signed-off-by:

Implementing job_abort() does not make sense on some drivers. This is not a problem, as the abort is not required to wait for the job to finish. Quite the opposite, drivers are encouraged not to wait. Demote v4l2_m2m_ops.job_abort from required to optional, and clean all drivers with dummy implementations. Signed-off-by:

As per the documentation, job_abort is not required to wait until the current job finishes. It is redundant to do so, as the core will perform the wait operation. Remove the wait infrastructure completely. Signed-off-by:

There is no way to control the standard of subdevices which are part of a media device. The ioctls which exists all target video devices explicitly and the idea is that the video device should talk to the subdevice. For subdevices part of a media graph this is not possible and the standard must be controlled on the subdev device directly. Add four new ioctls to be able to directly interact with subdevices and control the video standard; VIDIOC_SUBDEV_ENUMSTD, VIDIOC_SUBDEV_G_STD, VIDIOC_SUBDEV_S_STD and VIDIOC_SUBDEV_QUERYSTD.

The external clock frequency was set to 23.88MHz by mistake because of a platform which cannot get closer to 24MHz. The supported by the driver external clock is 24MHz so set it correctly and also fix the values of the pixel clock and link clock. However allow 1% tolerance to the external clock as this difference is small enough to be insignificant. Signed-off-by:

For some types of tuners (Philips FMD1216ME(X) MK3 currently) we know that letting TDA9887 output port 1 remain high (inactive) will switch FM radio to mono mode. Let's make use of this functionality - nothing changes for the default stereo radio mode. Tested on a Medion 95700 board which has a FMD1216ME tuner. Signed-off-by:
