Enable linedisp library integration into existing kernel devices (like LED class) to provide a uniform 7-segment userspace API without creating separate child devices, meeting the consistent interface while maintaining coherent device hierarchies. This allows uniform 7-segment API across all drivers while solving device proliferation and fragmented userspace interfaces. The sysfs attributes appear in one of the two locations depending on usage: 1. On linedisp.N child devices (legacy linedisp_register()) 2. On the parent auxdisplay device (new linedisp_attach()) Functionality is identical in both modes. Existing consumers of linedisp_register() are unaffected. The new API enables drivers like TM16XX to integrate 7-segment display functionality seamlessly within their LED class device hierarchy.

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 reStructuredText 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.
