CTRLMMR_MCU_SPI1_CTRL register controls if MCU_SPI1 is directly connected to SPI3 in the MAIN Domain (default) or if MCU_SPI1 and SPI3 are independently pinned out. By default, the field SPI1_LINKDIS (Bit 0) is set to 0h. In order to disable the direct connection, the SPI1_LINKDIS (Bit 0) needs to be set to 1h. Model this functionality as a "reg-mux" device and based on the idle-state property, enable/disable the connection bewtween MCU_SPI1 and MAIN_SPI3. The register field description has been referred from J7200 TRM [1] (Table 5-517. CTRLMMR_MCU_SPI1_CTRL Register Field Descriptions).

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.
