The HDMI driver is written with readl/writel I/O to the registers. However, to support the A31 variant, which has a different layout for the DDC registers, it was recommended to use regfields to have a cleaner implementation. To use regfields, we need to create an underlying regmap. This patch only adds the regmap. It does not convert the existing driver accesses to use regmap.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. 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.
