[PATCH 00/19] staging:iio:buffer clean ups.

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

Hi Greg,

Dependent on previous two series:

Add scan demux unit..
iio:staging:inkern pull interface for staging tree.

This lot are the result of a thorough read of the buffering code.
Nothing terribly interesting. Some are things allowed by example
due to the new version of the sw_ring_preenable function in the
earlier series.

Lots of them are removal of the ability to query into a running
buffer to get the most recent value.  There was no real known
usecase for this. Only one buffer supported it. It made for
some really fiddly code.  Hence after a discussion on linux-iio
we decided to stop drivers doing this and remove the support for

Note the discussion involved the possibility that an equivalent
more general option may come back as part of the work to
support simultaneous in kernel pull and push users of an IIO
device.  Still this code was not needed for that!

The last 3 patches originally fell in a separate series and
so have probably slipped by everyone.  They are trivial
though so I am reasonably happy to send them on to you now.



Previous text:

A fairly straight forward set of cleanups of the buffer code.
Recent discussion concluded that having access to channels being
captured to a buffer by sysfs was an unnecessary complexity so that
ist dropped.  The other patches get rid of some infrastructure and
move the setup ops from a buffer instance to the device (as they will
be relevant to all buffers when we allow more than one)

Anyhow, if people could verify I haven't messed any of this up, that
would be great!

(following is for the last 3).

These were after the inkern pull interface stuff in my tree, but
with a closer look they clearly aren't dependent on it so I'll tack
them on to the end of the previous series if everyone is happy.
