[PATCH 0/7] Add scan demux unit and use it in max1363

[Jonathan Cameron <jic23@kernel.org>]

The last patch technically is a simple bug fix, but included here as
it came up during testing of this series.

The 'interesting' bits are the rewrite of iio_sw_buffer_preenable. I'd like
people with drivers currently using that function to test and see what
I have broken.  We should also be able to drop a number of cases in specific
drivers in favour of this version.

The demux unit is designed to offer a straight path with little or no
overhead if the client (here still the IIO buffer) needs all the data and to
only get in the way when a subset of the active scan mask is requested.

I may well have messed this up so please please test this set.

Thanks,

Jonathan

Jonathan Cameron (7):
  staging:iio:find iio channel from scan index util function
  staging:iio:buffer add a cache of the timestamp scan index.
  staging:iio: add hook to allow core to perform scan related config.
  staging:iio: make iio_sw_buffer_preenable much more general.
  staging:iio: add demux optionally to path from device to buffer
  staging:iio:adc:max1363 use new demuxing support.
  staging:iio:adc:max1363 correctly set channels as big endian.
