Move the main COMEDI driver headers out of "drivers/comedi/" into new directory "include/linux/comedi/". These are "comedidev.h", "comedilib.h", "comedi_pci.h", "comedi_pcmcia.h", and "comedi_usb.h". Additionally, move the user-space API header "comedi.h" into "include/uapi/linux/" and add "WITH Linux-syscall-note" to its SPDX-License-Identifier. Update the "COMEDI DRIVERS" section of the MAINTAINERS file to account for these changes.

* level inputs that can fire the trigger.
|
|
*
|
|
* These are used with the %INSN_CONFIG_DIGITAL_TRIG configuration instruction.
|
|
* The data for the configuration instruction is as follows...
|
|
*
|
|
* data[%0] = %INSN_CONFIG_DIGITAL_TRIG
|
|
*
|
|
* data[%1] = trigger ID
|
|

|
|
* data[%3] = configuration parameter 1
|
|
*
|
|
* data[%4] = configuration parameter 2
|
|
*
|
|
* data[%5] = configuration parameter 3
|
|
*
|
|
* The trigger ID (data[%1]) is used to differentiate multiple digital triggers
|
|
* belonging to the same subdevice. The configuration operation (data[%2]) is
|
|
* one of the enum comedi_digital_trig_op values. The configuration
|
|
* parameters (data[%3], data[%4], and data[%5]) depend on the operation; they
|
|
* are not used with %COMEDI_DIGITAL_TRIG_DISABLE.
|
|
*
|
|
* For %COMEDI_DIGITAL_TRIG_ENABLE_EDGES and %COMEDI_DIGITAL_TRIG_ENABLE_LEVELS,
|
|
* configuration parameter 1 (data[%3]) contains a "left-shift" value that
|
|
* specifies the input corresponding to bit 0 of configuration parameters 2
|
|
* and 3. This is useful if the trigger has more than 32 inputs.
|
|
*
|
|
* For %COMEDI_DIGITAL_TRIG_ENABLE_EDGES, configuration parameter 2 (data[%4])
|
|
* specifies which of up to 32 inputs have rising-edge sensitivity, and
|
|
* configuration parameter 3 (data[%5]) specifies which of up to 32 inputs
|
|
* have falling-edge sensitivity that can fire the trigger.
|
|
*
|
|
* For %COMEDI_DIGITAL_TRIG_ENABLE_LEVELS, configuration parameter 2 (data[%4])
|
|
* specifies which of up to 32 inputs must be at a high level, and
|
|
* configuration parameter 3 (data[%5]) specifies which of up to 32 inputs
|
|
* must be at a low level for the trigger to fire.
|
|
*
|
|
* Some sequences of %INSN_CONFIG_DIGITAL_TRIG instructions may have a (partly)
|
|
* accumulative effect, depending on the low-level driver. This is useful
|
|
* when setting up a trigger that has more than 32 inputs, or has a combination
|
|
* of edge- and level-triggered inputs.

|

*
|
|
* NOTE ABOUT THE CHOICE OF NAMES HERE AND THE CAMELSCRIPT:
|
|
* The choice to use CamelScript and the exact names below is for

* maintainability, clarity, similarity to manufacturer's documentation,
|
|
* _and_ a mitigation for confusion that has plagued the use of these drivers
|
|
* for years!
|
|
*
|
|
* More detail:
|
|
* There have been significant confusions over the past many years for users
|
|
* when trying to understand how to connect to/from signals and terminals on
|
|
* NI hardware using comedi. The major reason for this is that the actual
|
|
* register values were exposed and required to be used by users. Several
|
|
* major reasons exist why this caused major confusion for users:
|
|
* 1) The register values are _NOT_ in user documentation, but rather in
|
|
* arcane locations, such as a few register programming manuals that are
|
|
* increasingly hard to find and the NI MHDDK (comments in example code).
|
|
* There is no one place to find the various valid values of the registers.
|
|
* 2) The register values are _NOT_ completely consistent. There is no way to
|
|
* gain any sense of intuition of which values, or even enums one should use
|
|
* for various registers. There was some attempt in prior use of comedi to
|
|
* name enums such that a user might know which enums should be used for
|
|
* varying purposes, but the end-user had to gain a knowledge of register
|
|
* values to correctly wield this approach.
|
|
* 3) The names for signals and registers found in the various register level
|
|
* programming manuals and vendor-provided documentation are _not_ even
|
|
* close to the same names that are in the end-user documentation.
|
|
*
|
|
* Similar, albeit less, confusion plagued NI's previous version of their own
|
|
* drivers. Earlier than 2003, NI greatly simplified the situation for users
|
|
* by releasing a new API that abstracted the names of signals/terminals to a
|
|
* common and intuitive set of names.
|
|
*
|
|
* The names below mirror the names chosen and well documented by NI. These
|
|
* names are exposed to the user via the comedilib user library. By keeping
|
|
* the names below, in spite of the use of CamelScript, maintenance will be
|
|
* greatly eased and confusion for users _and_ comedi developers will be
|
|
* greatly reduced.
