[PATCH v3 0/2] iio: stm32 trigger: Add quadrature device and counter

From: Benjamin Gaignard
Date: Mon Mar 27 2017 - 05:46:05 EST


A first encoder IIO driver (104-quad-8) with a count channel already exist.
STM32 driver have the same type of feature but with different counting modes.
Some parts, like counting direction (up/down) could be generalized so move the
corresponding documentation from driver file to sysfs-bus-iio.

version 3:
- fix typo in documentation
- change some functions names

version 2:
- since iio: Generalize counting direction modes commit of version has being
pushed in iio.git testing branch I have remove it from this serie.
- split the original attribute in 2: one for quadrature modes and one for
enable modes.
- add scale info
- change modes to more generic names to be able to merge them with 104-quad-8
in the futur.
