Multi-planar API is as a backwards-compatible extension of the V4L2 API,
which allows video buffers to consist of one or more planes. Planes are
separate memory buffers; each has its own mapping, backed by usually
separate physical memory buffers.
Many different uses for the multi-planar API are
Hello,
After 9 months since the first proposal, lots of discussion and many changes,
including an almost full redesign between versions 3 and 4, I present the
patches that add the fifth version of the multi-planar API for V4L2.
I am posting patches first for everyone to be able to take a look

Hi,
This is mostly same patchset.
I addressed the comments of Andy Walls.
Now IR decoding is done by a separate thread, and this fixes
the race, and unnesesary performance loss due to it.

Some ir input devices have small buffer, and interrupt the host
each time it is full (or half full)
Add a helper that automaticly handles timeouts, and also
automaticly merges samples of same time (space-space)
Such samples might be placed by hardware because size of
sample in the buffer is small
This way it is possible to use evtest to create keymap for unknown remote.
