Linux kernel source tree

If HTI (also sometimes called HDPORT) is enabled at startup, it may be using some of the PHYs and DPLLs making them unavailable for general usage. Let's read out the HDPORT_STATE register and avoid making use of resources that HTI is already using. v2: - Fix minor checkpatch warnings v3: - Just readout HDPORT_STATE register once during init and then parse it later as needed. - Add a 'has_hti' device info flag to track whether we should readout HDPORT_STATE or not. We can skip the platform/flag tests later since the hti_state in dev_priv will remain 0 for platforms it does not apply to. - Move PLL masking into icl_get_combo_phy_dpll() since at the moment RKL is the only platform that has HTI.

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.
