Outputs C and D on EHL are combo PHY outputs and thus should not be using the same TC AUX power well handlers as ICL. And even though icl_combo_phy_aux_power_well_ops works okay for EHL/JSL combo PHYs none of its special handling is actually necessary for this platform: * EHL/JSL don't actually need to program PORT_CL_DW12 * Display WA #1178 does not apply to EHL/JSL Thus we can simply drop back to using our standard "hsw-style" power well ops for EHL AUX power wells.

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.
