cadence-quadspi has a builtin Auto-HW polling funtionality using which it keep tracks of completion of write operations. When Auto-HW polling is enabled, it automatically initiates status register read operation, until the flash clears its busy bit. cadence-quadspi controller doesn't allow an address phase when auto-polling the busy bit on the status register. Unlike SPI NOR flashes, SPI NAND flashes do require the address of status register when polling the busy bit using the read register operation. As Auto-HW polling is enabled by default, cadence-quadspi returns a timeout for every write operation after an indefinite amount of polling on SPI NAND flashes. Disable Auto-HW polling completely as the spi-nor core, spinand core, etc. take care of polling the busy bit on their own.

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.
