The BCM590xx PMUs have two I2C registers for reading the PMU ID and revision. The revision is useful for subdevice drivers, since different revisions may have slight differences in behavior (for example - BCM59054 has different regulator configurations for revision A0 and A1). Check the PMU ID register and make sure it matches the DT compatible. Fetch the digital and analog revision from the PMUREV register so that it can be used in subdevice drivers. Also add some known revision values to bcm590xx.h, for convenience when writing subdevice drivers.

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.
