Greg Kroah-Hartman 78a66b00d9 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 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. -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQIcBAABCAAGBQJVdgz8AAoJEFSFNJnE9BaIMSoP/RYq9yzkRtQ+T7ZnxdW0uaVK W8zhcg9W62dKbu0ccMVI+ESv9bg+3Ti/ZHE2251olYzXER5qrUUqB7llpgJeoni+ ft1RyOZYYTWqv/2fx9Jdn+h4792tv4nykdgY3YhxR3anPD5Tb3PcRryCJ739d6xL c8HZedMP9znbC7BiEzRcLBPiyiv+NFKHF0T6LCkwlTGoe6q+8yaW1blmxTRmtpnD Wpf08/vafBmbjUmxfcvtgyOr73D6/kNOk9xYtvbQguD5nG5oHRe96nlaTtW7//hi ybP0q+UPV7Hss1pgufEZufPfWglsqOpIWJ7diUyXzvf9x7FAUd2nuiAHKybUg4bT yC2dSCVgRAa1zLEwcTub5MNtjkcfM0l9wsnCCIssD5p9s4EEenge1UjHsV7zm/KA JzBKBRz98Mo6m+F2gWZkkpuIb9UbI99oLBVDzhFBYf77b1L8curJ+pBH2lcICMun K5+WC3itkl7QImbyrCXdHmu9/oWS2+MSVHsmmL4omMFb071/C1iAUCIJahJrbgcy jIjaNJp3WgOplQp4tlP6WtsbzHh0DzjjLj+RKFv2mqYMlHhhAFdoH68qXPxG3kYo IxyGh7sH7ic5BQyt4B8/GhxakDuf55O/kyS7t01B3c5JbJp/IAbobfWkpCtuICYV GIIZTKI5kJb1Q8P7AbUD =sNVc -----END PGP SIGNATURE----- Merge tag 'iio-for-v4.2c' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next Jonathan writes: Third round of new IIO drivers, cleanups and functionality for the 4.2 cycle.
