Devices with specific voltage requirements should not request voltage from the driver, but instead rely on the system configuration to define appropriate voltages for each rail. This ensures that PMIC and board variations are accounted for, something that the 0.1V range in the hci_qca driver currently tries to address. But on the Lenovo Yoga C630 (with wcn3990) vddch0 is 3.1V, which means the driver will fail to set the voltage.

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.
