When using devicetree for configuration, interrupt trigger type should be described in the dts file, not hard-coded in the C code. The mtk-sd silicon in the mt7621 soc uses an active-high interrupt and so cannot be used with the current code. So replace IRQF_TRIGGER_LOW with IRQF_TRIGGER_NONE. Also IRQF_ONESHOT is not needed - it is used for threaded interrupt handlers, and this driver does not used a threaded interrupt handler. So remove that setting.

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.
