In the current state, A33 NAND controllers use PIO during transfers. Throughput can be increased thanks to the use of DMA (mostly during reads, because of the ECC pipelining feature). Besides the usual addition of DMA DT properties, because the A33 NAND DMA handling is different than for older SoCs, we must also update the compatible which has recently been introduced for this purpose.

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.
