The RTC_OSC_REG register is 32-bit, but the useful information is found in the 7 least significant bits (bits 7-31 are reserved). And in fact, as you can see from the code, all read accesses are 8-bit, as well as some writes. Let's make sure all writes are 8-bit. Moreover, in contexts where consecutive reads / writes after the busy check must take place within 15 us, it is better not to waste time on useless accesses.

README
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.
