Subject[RFC 0/9] spawn hrtimer trigger from client driver upon enabling buffer
Date
this builds upon the sw-trigger / hrtimer series from Daniel[1]
in order to create the trigger upon enabling the buffer when the
sampling frequency is known. This is useful for devices without
hardware streaming scheme, to avoid the complexity of creating
a separate trigger through configfs, and then setting
the sw-trigger frequency from both device0 and the trigger.

Daniel Baluta (5):
configfs: Allow dynamic group creation
iio: core: Introduce IIO configfs support
iio: core: Introduce IIO software triggers
iio: trigger: Introduce IIO hrtimer based trigger
iio: Documentation: Add IIO configfs documentation

Marc Titinger (4):
iio: ina2xx: add direct IO support for TI INA2xx Power Monitors
iio: ina2xx: add triggered buffer
iio: buffer: allow for last-second trigger spawning from device driver
iio: (RFC) illustrate creation/destruction of hrtimer trigger upon
buffer enable
