The driver does not try to power down the rails at system suspend or when touchscreen is not in use, but rather enables regulators at probe time. Power savings are achieved by requesting the controller to enter low power mode. Switch to devm_regulator_bulk_get_enable() instead of separately requesting regulators, enabling them, and installing a custom devm-action to disable them on unbind/remove, which simplifies the code.

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.
