Reading the 7 timetamp registers currently involves reading 25 registers solely to be able to print the content of the three control registers, in addition to the 7 timestamp registers. This print never occurs, unless the user enables dynamic debug in this driver or set CONFIG_RTC_DEBUG. Reading the timestamp registers should consist of reading 7 consecutive timestamp registers. This patch optimize the performance of reading the timestamp registers by reading 7 consecutive registers instead of 25, and dropping the print of the control registers.

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.
