iio: st_accel: support the LIS331DL sensor (2015-06-08 22:21:18 +0100)
----------------------------------------------------------------
Third round of new IIO drivers, cleanups and functionality for the 4.2 cycle.
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 embarrassed by how bad some of these were! Are well,
much more refined and less bug prone now.
These cover lots of stuff like un-handled 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 labelling which buffer modes a given buffer implementation
supports.
- In the case of hardware buffers, require strict scan matching rather than
matching to a super set. 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 user space.
Driver functionality improvements
* 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.
