Lucas De Marchi 4e53840fdf drm/i915/icl: Introduce new macros to get combophy registers
combo-phy register instances are at same offset from base for each
combo-phy port, i.e.

Port A base offset: 0x16200
Port B base offset: 0x6C000

All the other addresses for both ports can be derived by calculating
offset to these base addresses.

PORT_CL_DW_OFFSET	0x0
PORT_CL_DW<x>		0 + x * 4

PORT_COMP_OFFSET	0x100
PORT_COMP_DW<x>		0x100 + x * 4

PORT_PCS_AUX_OFFSET     0x300
PORT_PCS_GRP_OFFSET     0x600
PORT_PCS_LN<y>_OFFSET   0x800 + y * 0x100

PORT_TX_AUX_OFFSET      0x380
PORT_TX_GRP_OFFSET      0x680
PORT_TX_LN<y>_OFFSET    0x880 + y * 0x100

And inside each PORT_TX_[AUX|GRP|LN] we add `dw * 4`.

Based on original patch by Mahesh Kumar <mahesh1.kumar@intel.com>.

v2: make port, dw and ln arguments follow the order in
    register's name

README

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.
