Commit941432d007("arm64: dts: allwinner: Drop non-removable from SoPine/LTS SD card") enabled the card detect GPIO for the SOPine module, along the way with the Pine64-LTS, which share the same base .dtsi. However while both boards indeed have a working CD GPIO on PF6, the polarity is different: the SOPine modules uses a "push-pull" socket, which has an active-high switch, while the Pine64-LTS use the more traditional push-push socket and the common active-low switch. Fix the polarity in the sopine.dtsi, and overwrite it in the LTS board .dts, to make the SD card work again on systems using SOPine modules.

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.
