[ Upstream commit941432d007] The SD card on the SoPine SoM module is somewhat concealed, so was originally defined as "non-removable". However there is a working card-detect pin (tested on two different SoM versions), and in certain SoM base boards it might be actually accessible at runtime. Also the Pine64-LTS shares the SoPine base .dtsi, so inherited the non-removable flag, even though the SD card slot is perfectly accessible and usable there. (It turns out that just *my* board has a broken card detect switch, so I originally thought CD wouldn't work on the LTS.) Drop the "non-removable" flag to describe the SD card slot properly.

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.
