2025-03-04Documentation: iio: Add ADC documentationMarcelo Schmitt
ADC inputs can be classified into a few different types according to how they measure the input signal, how restrained the signal is, and number of input pins. Even though datasheets tend to provide many details about their inputs and measurement procedures, it may not always be clear how to model those inputs into IIO channels. For example, some differential ADCs can have their inputs configured into pseudo-differential channels. In that configuration, only one input connects to the signal of interest as opposed to using two inputs of a differential input configuration. Datasheets sometimes also refer to pseudo-differential inputs as single-ended inputs even though they have distinct physical configuration and measurement procedure. Document consolidated ADC input types and how they are usually described and supported in device tree and IIO, respectively.

Allow setting frequency below 1Hz or sub 1Hz precision. Useful for slow sensors like ALS. Test frequency is set properly: modprobe iio-trig-hrtimer && \ mkdir /sys/kernel/config/iio/triggers/hrtimer/t1 && \ cd /sys/bus/iio/devices/triggerX ; for i in 1 .1 .01 .001 ; do echo $i > sampling_frequency cat sampling_frequency done Signed-off-by: Gwendal Grignou <gwendal@chromium.org> Reviewed-by: Andy Shevchenko <andy.shevchenko@gmail.com> Link: https://lore.kernel.org/r/20210226014733.2108544-1-gwendal@chromium.org Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com>
