The HDC3020 sensor carries out periodic measurements during normal operation, but as long as the power supply is enabled, it will carry on in low-power modes. In order to avoid that and reduce power consumption, the device can be switched to Trigger-on Demand mode, and if possible, turn off its regulator. According to the datasheet, the maximum "Power Up Ready" is 5 ms. Add resume/suspend pm operations to manage measurement mode and regulator state.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
