n preparation for adding support for the Renesas RZ/V2H(P) SoC, this patch introduces a mechanism to pass SoC-specific information via OF data in the DSI driver. This enables the driver to adapt dynamically to various SoC-specific requirements without hardcoding configurations. The MIPI DSI interface on the RZ/V2H(P) SoC is nearly identical to the one on the RZ/G2L SoC. While the LINK registers are shared between the two SoCs, the D-PHY registers differ. Also the VCLK range differs on both these SoCs. To accommodate these differences `struct rzg2l_mipi_dsi_hw_info` is introduced and as now passed as OF data. These changes lay the groundwork for the upcoming RZ/V2H(P) SoC support by allowing SoC-specific data to be passed through OF.

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 reStructuredText 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.
