These register reads and writes are sometimes directly next to each other in the register address space. Let's use regmap bulk read/write APIs to get the data with one transfer instead of multiple i2c transfers. This helps cut down on the number of transfers in the case of something like reading an EDID where we read in blocks of 16 bytes at a time and the last for loop here is sending an i2c transfer for each of those 16 bytes, one at a time. Ouch!

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.
