2015-06-13staging: comedi: das08: rename and split DAS08JR_DIOIan Abbott1-4/+5
The `DAS08JR_DIO` macro contains the offset to the read-only digital input register and write-only digital output register on the "JR" boards. Replace the macro with two new macros (with the same numeric value) named `DAS08JR_DI_REG` for the digital input register and `DAS08JR_DO_REG` for the digital output register, and add some comments.

The `DAS08_INTE` macro contains a mask for the "INTE" bit in the control register (except on "JR" boards). Setting it to 1 enables interrupts. Setting it to 0 disables interrupts and clears the "IRQ" bit in the status register. Rename the macro to `DAS08_CONTROL_INTE` and add a comment. Also use the `BIT()` macro to define its value. (Note: the driver does not currently enable interrupts.)

The `DAS08_MUX_MASK` macro is a bitmask for the control register corresponding to the analog input multiplexor channel selection bits. Rename it to `DAS08_CONTROL_MUX_MASK` and add a comment. Note that the current setting of the multiplexor can also be read from the same bit positions in the status register, but the driver does not use it. Add a comment to that effect.

The Comedi "das08.h" header file is included by drivers for the ComputerBoards/MeasurementComputing and Keithley Metrabyte boards in the DAS08 series. It does not compile cleanly when it is the first header included by the ".c" file.

2015-06-13staging: comedi: das08: improve test for programmable gainIan Abbott1-1/+1
`das08_ai_rinsn()` handles Comedi `INSN_READ` instructions for the AI subdevice. This programs the gain for the analog input channel if the board has support for that, and acquires data from the channel. If programmable gain is supported, the gain code is read from the array pointed to by `devpriv->pg_gainlist` indexed by the range index. The function assumes that programmable gain is supported if the AI subdevice's range table supports more than one range. Replace that with a more direct test for `devpriv->pg_gainlist` being non-NULL, as it is only initialized to a non-NULL pointer for boards that support programmable gain. This will also allow range tables to be included for convenience for those boards that support multiple ranges by DIP switches. Those boards are currently initialized to use a single "unknown" range.

2015-06-13staging: comedi: das08: use indexed initializer for AI range table typesIan Abbott2-12/+13
The "das08" common module for DAS08 ISA, PCI, and PCMCIA drivers includes a predefined set of AI range tables. The static board data (of type `struct das08_board_struct`) for a particular board contains an index in its `ai_pg` member (of type `enum das08_lrange`) indicating which of the predefined AI range tables to use. The "das08" common module looks up this index in `das08_ai_lranges[]` to get a pointer to the predefined range table for the board. The same index is also looked up in `das08_gainlists[]` to get a corresponding pointer to a list of hardware gain values for each range supported by the board (NULL for boards without programmable gain). To make this clearer, used indexed initializers for `das08_ai_lranges[]` and `das08_gainlists[]`, using the enumerated constants from `enum das08_lrange` as the indices. Also add a short comment to the definition of `enum das08_lrange`.

2015-06-13staging: comedi: cb_pcimdas: fix handlers for DI and DO subdevicesIan Abbott1-4/+4
Normally, low-level Comedi drivers set an `insn_bits` handler for digital input (DI), digital output (DO) and digital input/output (DIO) subdevice types to handle normal reading and writing of digital channels. The "cb_pcimdas" driver currently has an `insn_read` handler for the DI subdevice and an `insn_write` handler for the DO subdevice. However, the actual handler functions `cb_pcimdas_di_insn_read()` and `cb_pcimdas_do_insn_write()` are written to behave like `insn_bits` handlers. Something's wrong there! To fix it, set the functions as `insn_bits` handlers and rename them for consistency.
