Subject: [GIT PULL for v4.5-rc1] media controller next gen patch series
Hi Linus,
That's the second part of the media patches. It contains the media controller
next generation patches, with is the result of one year of discussions and
development. It also contains patches to enable media controller support
at the DVB subsystem.
The goal is to improve the media controller to allow proper support for
other types of Video4Linux devices (radio and TV ones) and to extend the
media controller functionality to allow it to be used by other subsystems
like DVB, ALSA and IIO.
In order to use the new functionality, a new ioctl is needed
(MEDIA_IOC_G_TOPOLOGY). As we're still discussing how to pack the struct
fields of this ioctl in order to avoid compat32 issues, I decided to add
a patch at the end of this series commenting out the new ioctl, in order
to postpone the addition of the new ioctl to the next Kernel version (4.6).
With that, no userspace visible changes should happen at the media
controller API, as the existing ioctls are untouched. Yet, it helps
DVB, ALSA and IIO developers to develop and test the patches adding media
controller support there, as the core will contain all required internal
changes to allow adding support for devices that belong to those
subsystems.
Regards,
Mauro
