The `DAS08_DO_MASK` macro is a bitmask for the control register
corresponding to the digital output channels (except on "JR" boards).
Rename it to `DAS08_CONTROL_DO_MASK` and add a comment.

channel states and returns the corresponding bits for the control
register (except on "JR" boards). Rename it to `DAS08_CONTROL_DO(x)`

The `DAS08_INTE` macro contains a mask for the "INTE" bit in the control

Setting it to 0 disables interrupts and clears the "IRQ" bit in the

comment. Also use the `BIT()` macro to define its value. (Note: the
driver does not currently enable interrupts.)

`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.

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`.

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.

Given Linus announced a 4.8rc coming up, hopefully time for one more
lot of IIO patches this cycle. Some of these are actually
improvements / fixes for patches earlier in the cycle.
New device support
* st_accel driver - support devices with 8 bit channels.
Cleanup
* A general cleanup of the iio tools under /tools/ from Hartmut.
I'm more than a little embarassed by how bad some of these were! Are well,
much more refined and less bug prone now.
These cover lots of stuff like unhandled error returns, memory leaks as
well as general refactoring to tidy the code up.
* iio_simple_dummy - fix memory leaks in the init functions, drop some
pointless error returns from functions that never generate errors and
make the module parameter explicitly unsigned.
* More buffer handling reworks from Lars-Peter, this time targetting hardware
buffers (a little used corner that looks likely to get more use in the near
future). Specifically:
- Always compute the masklength as inkernel buffer users may need it.
- Add a means of labeling which buffer modes a given buffer implementation
supports.
- In the case of hardware buffers, require strict scan matching rather than
matching to a superset. Currently the demux is bypassed by these drivers
(this may well not change for efficiency reasons) so allowing a superset
of channels to be selected would otherwise lead to more data than requested
confusing userspace.
Driver funcationality improvments
* mmc35240 - adds a compensation to the raw values as borrowed form Memsic's
own input driver.
* mma8452
- event support
- event debouncing
- high pass filter configuration
- triggers
* vf610 - allow conversion mode to be adjusted
Fixlets
* mmc35240
- Off by one error that by coincidence had no real effect.
- i2c_device_name should be lowercase.
- Lack of null terminator at end of attributes array.
- Avoid computing the fractional part of the magnetic field by moving
the scaling into userspace where floating point is available to simplify
the maths.
- Use a smaller sleep before assuming the measurement is done. This is
safe and improves the possible polling rate.
- Fix sensitivity on z-axis - datasheet disagrees with Memsic's releasedd
code and the value used in the code seems to be correct.
* stk3310 - make a local variable signed to ensure error handling works.
* twl4030
- fix calculation of the temperature sense current - bug unlikely
to have ever been noticed as the difference is small.
- Fix errors in descriptions.
