On some Cherry Trail systems the GPU ACPI fwnode has power-resources which point to the PMIC, which is connected over the LPSS I2C7 controller. Due to probe ordering currently we resume the GPU and thus try to access the ACPI power-resources before the I2C controller has been resumed. This leads to the following errors: i2c_designware 808622C1:06: controller timed out ACPI Error: AE_ERROR, Returned by Handler for [UserDefinedRegion] ACPI Error: Method parse/execution failed \_SB.P18W._ON, AE_ERROR video LNXVIDEO:00: Failed to change power state to D0 This commit adds a RPM consumer link from the GPU (which has a LNXVIDEO HID) to the CHT LPSS I2C7 controller, so that the I2C controller gets resumed before the GPU is resumed.

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
