10 years agostaging: comedi: dt282x: automatically handle D/A data format

staging: comedi: dt282x: automatically handle D/A data format

The DT2821 series board have jumpers that set the output range for
the two Analog Output channels. The range_table for the Analog Output
subdevice provides all possible ranges to the user. When a unipolar
range is selected the board expects the data to be in a straight
binary format. When a bipolar range is select the data should be in
two's complement format.

Currently, the user passes some configuration options when attaching
to the driver to select the data format for each channel. If the
user does not pass the config options, the data format is assumed to
be straight binary.

The Analog Output subdevice now has a range_table that provides the
user will all possible ranges. Use the range information to determine
if the data values need to be munged into two's complememnt values
and deprecate the config options.

setting it doesn't cause any problems in the driver it just causes the

Pull i2c new drivers from Wolfram Sang:
 "Here is a pull request from i2c hoping for the "new driver" rule.

  Originally, I wanted to send this request during the merge window, but
  code checkers with very recent additions complained, so a few fixups
  were needed.  So, some more time went by and I merged rc1 to get a
  stable base"

So the "new driver" rule is really about drivers that people absolutely
need for the kernel to work on new hardware, which is not so much the
case for i2c.  So I considered not pulling this, but eventually
relented.

Just for FYI: the whole (and only) point of "new drivers" is not that
new drivers cannot regress things (they can, and they have - by
triggering badly tested code on machines that never triggered that code
before), but because they can bring to life machines that otherwise
wouldn't be useful at all without the drivers.

So the new driver rule is for essential things that actual consumers
would care about, ie devices like networking or disk drivers that matter
to normal people (not server people - they run old kernels anyway, so
mainlining new drivers is irrelevant for them).

Merge branch 'perf-urgent-for-linus' of git://git./linux/kernel/git/tip/tip

Pull perf fixes from Ingo Molnar:
 "This is larger than usual: the main reason are the ARM symbol lookup
  speedups that came in late and were hard to resist.

  There's also a kprobes fix and various tooling fixes, plus the minimal
  re-enablement of the mmap2 support interface"
