This series adds power management for the hdc3020 humidity and temperature sensor as well as control over the reset signal the device provides. The hdc3020 carries out measurements automatically, which is not necessary in low-power modes. Furthermore, if the low-power configuration turns off the device, proper initialization is required to account for the setup times and initial status register value. This device provides an active low reset signal that must be handled if connected. This signal can be used by the driver to keep the device under minimal power consumption during low-power modes if the power supply stays active. This series requires the last additions to the driver to handle events [1] as well as the fix to include the entries in the Makefile and Kconfig files [2]. There is still no branch where everything is included. Therefore, iio/testing has been used as basis and the fix has been added to the series as it has been applied to iio/fixes-togreg to make code testing and validation possible.
