[ Upstream commit 5b78223f55a0f516a1639dbe11cd4324d4aaee20 ] The Intel Crystal Cove PMIC has 2 different variants, one for use with Bay Trail (BYT) SoCs and one for use with Cherry Trail (CHT) SoCs. So far we have been using an ACPI _HRV check to differentiate between the 2, but at least on the Microsoft Surface 3, which is a CHT device, the wrong _HRV value is reported by ACPI. So instead switch to a CPU-ID check which prevents us from relying on the possibly wrong ACPI _HRV value.

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.
