The latest Cadence IP splits some of the existing registers into two, separated by a fixed offset. The bitfields themselves remain at the same position, so we can use new helpers to dynamically add the fixed offset. For example, the existing MCP_CONFIG is now split in two with MCP_CONFIG and IP_MCP_CONFIG (the naming comes directly from the design document). This patch adds helpers to access registers with the IP_ prefix. The addition of the 'ip' prefix for helpers, registers and bitfields is intentional to help reviewers spot any mistake. For existing solutions, the offset is exactly zero so there's no functional change - the MCP_CONFIG and IP_MCP_CONFIG are aliased to the same address.

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.
