Hans de Goede 06e577b45d mfd: arizona: Add MODULE_SOFTDEP("pre: arizona_ldo1")
The (shared) probing code of the arizona-i2c and arizona-spi modules
takes the following steps during init:

1. Call mfd_add_devices() for a set of early child-devices, this
includes the arizona_ldo1 device which provides one of the
core-regulators.

2. Bulk enable the core-regulators.

3. Read the device id.

4. Call mfd_add_devices() for the other child-devices.

This sequence depends on 1. leading to not only the child-device
being created, but also the driver for the child-device binding
to it and registering its regulator.

This requires the arizona_ldo1 driver to be loaded before the
shared probing code runs. Add a softdep for this to both modules to
ensure that this requirement is met.

Note this mirrors the existing MODULE_SOFTDEP("pre: wm8994_regulator")
in the wm8994 code, which has a similar init sequence.

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.
