The comedi code came into the kernel back in 2008, but traces its lifetime to much much earlier. It's been polished and buffed and there's really nothing preventing it from being part of the "real" portion of the kernel. So move it to drivers/comedi/ as it belongs there. Many thanks to the hundreds of developers who did the work to make this happen.

* Devices: [National Instruments] DAQCard-1200 (daqcard-1200)

* Status: works

|
|
* Thanks go to Fredrik Lingvall for much testing and perseverance in
|
|
* helping to debug daqcard-1200 support.
|
|
*
|
|
* The 1200 series boards have onboard calibration dacs for correcting
|
|
* analog input/output offsets and gains. The proper settings for these
|
|
* caldacs are stored on the board's eeprom. To read the caldac values
|
|
* from the eeprom and store them into a file that can be then be used by
|
|
* comedilib, use the comedi_calibrate program.
|
|
*
|
|
* Configuration options: none
|
|
*
|
|
* The daqcard-1200 has quirky chanlist requirements when scanning multiple
|
|
* channels. Multiple channel scan sequence must start at highest channel,
|
|
* then decrement down to channel 0. Chanlists consisting of all one channel
|
|
* are also legal, and allow you to pace conversions in bursts.
