The driver supports continuous reads of temperature, relative humdity and CO2 concentration. There is an interval of 5 seconds between readings. During this interval the drivers checks if the sensor has new data available. The driver is based on the scd30 driver. However, The scd4x has become too different to just expand the scd30 driver. I made a new driver instead of expanding the scd30 driver. I hope I made the right choice by doing so? Changes since v1: dt-bindings: - Separated compatible string for each sensor type scd4x.c: - Changed probe, resume and suspend functions to static - Added SIMPLE_DEV_PM_OPS function call for power management operations.
