2019-06-21media: vivid: add CEC support to display present ctrlJohan Korsnes
Set/invalidate physical addresses based on the configuration of the display present control. This is relevant not only when the display present control is modified, but also when the Vivid instance EDID is set/cleared.

2019-06-21media: vivid: reorder CEC allocation and control set-upJohan Korsnes
CEC adapters and controllers (handlers) are now set up as follows: 1. Allocate CEC adapters: setup of control handlers in next step requires these adapters to be allocated. 2. Setup of control handlers: This must be done prior to registering and exposing the adapters to user space to avoid a race condition. 3. Register CEC adapters: make them available to user space.

2019-06-21media: staging: media: tegra-vde: Manually pack UAPI structuresDmitry Osipenko
The __packed macro isn't available in userspace with the kernel headers. Checkpatch asks to use the macro, which is unwanted in a case of a UAPI header. There is no much benefit in a tight packing of the structures, hence let's pack them manually to cleanup things a tad. Note that there is no old-stable userspace that will suffer from this change, hence it's fine to change the ABI. In a result also more space is reserved for a possible future expansion of the UAPI as it was already shown that more fields will be needed for a later SoC generations.

When the application calls VIDIOC_DQBUF with the DMABUF memory type, the v4l2_buffer structure (or v4l2_plane structures) are filled with DMA-buf file descriptors. However, the current documentation does not explain whether those are new file descriptors referring to the same DMA-bufs or just the same integers as passed to VIDIOC_QBUF back in time. Clarify the documentation that it's the latter.
