Some Cherry Trail boards have a dependency between the SDHCI host controller used for SD cards and an external PMIC accessed via I2C. Add a device link between the SDHCI host controller (consumer) and the I2C adapter (supplier). This patch depends on a fix to devices links, namely commit0ff26c662d("driver core: Fix device link deferred probe"). And also either, commit126dbc6b49("PM: i2c-designware-platdrv: Clean up PM handling in probe"), or patch "PM / runtime: Fix handling of suppliers with disabled runtime PM".

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
