The 104-QUAD-8 is capable of monitoring the outputs of eight encoders via four on-board LSI/CSI LS7266R1 24-bit dual-axis quadrature counter chips. Core functions handled by the LS7266R1, such as direction and total count, are available. Performing a write to a counter's IIO_CHAN_INFO_RAW sets the counter and also clears the counter's respective error flag. Although the counters have a 25-bit range, only the lower 24 bits may be set, either directly or via a counter's preset attribute. Interrupts are not supported by this driver. This driver adds IIO support for the ACCES 104-QUAD-8 and ACCES 104-QUAD-4. The base port addresses for the devices may be configured via the base array module parameter.

This patchset adds support for both IR and RED LED channels which can be processed in userspace to determine heart rate and blood oxygen levels.

This patch adds the generic infrastructure for handling software triggers. Software interrupts sources are kept in a iio_trigger_types_list and registered separately when the associated kernel module is loaded. Software triggers can be created directly from drivers or from user space via configfs interface. To sum up, this dynamically creates "triggers" group to be found under /config/iio/triggers and offers the possibility of dynamically creating trigger types groups. The first supported trigger type is "hrtimer" found under /config/iio/triggers/hrtimer.

The group will appear under <mount-point>/iio/, usually /config/iio. We introduce configfs support in IIO in order to be able to easily create IIO objects from userspace. The first supported IIO objects are triggers introduced with next patches.

A new config menu entry called IIO dummy driver has also been added in the Industrial I/O support menu, corresponding to this driver.
