[ Upstream commit fc94224c2e0ae8d83ac511a3ef4962178505469d ]
The datasheet says that VDD12 must be enabled and at full voltage before
VDD33 is enabled.
Reorder the bulk regulator supply names so that VDD12 is enabled before
VDD33. Any enable ramp delays should be handled by setting proper
constraints on the regulators.

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.
