Linux kernel source tree
e8977917e1
The PM8916 device specification [1] documents a programmable range of
1.75V to 3.337V with 12.5mV steps for the PMOS LDOs in PM8916. This
range is also used when controlling the regulator directly using the
qcom_spmi-regulator driver ("ult_pldo" there).
However, for some reason the qcom_smd-regulator driver allows a much
larger range for the same hardware component. This could be simply a
typo, since the start of the range is essentially just missing a '1'.
In practice this does not cause any major problems, since the driver
just sends the actual voltage to the RPM firmware instead of making use
of the incorrect voltage selector. Still, having the wrong range there
is confusing and prevents the regulator core from validating requests
correctly.

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.
