Allow to extend expression of sub nodes to optionally indicate bit
position. This extension is needed to distinguish between different bit
positions in the same address.
For example, there are two nvmem nodes starting with bit 4 and bit 0
at the same address 0x54. In this case, it can be expressed as follows.
trim@54,4 {
reg = <0x54 1>;
bits = <4 2>;
};
trim@54,0 {
reg = <0x54 1>;
bits = <0 4>;
};

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.
