Currently the suspend reg_field maps to the pmic voltage selection bits
and is used during suspend_enabe/disable() and during get_mode(). This
seems to be wrong for both use cases.
Use case one (suspend_enabe/disable):
Those callbacks are used to mark a regulator device as enabled/disabled
during suspend. Marking the regulator enabled during suspend is done by
the LDOx_CONF/BUCKx_CONF bit within the LDOx_CONT/BUCKx_CONT registers.
Setting this bit tells the DA9062 PMIC state machine to keep the
regulator on in POWERDOWN mode and switch to suspend voltage.
Use case two (get_mode):
The get_mode callback is used to retrieve the active mode state. Since
the regulator-setting-A is used for the active state and
regulator-setting-B for the suspend state there is no need to check
which regulator setting is active.

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 Restructured Text 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.
