This reworks the driver to make use of ->exec_op() callback. The command sequencer of the VF610 NFC aligns well with the new ops interface. The operations are translated to a NFC command code while filling the necessary registers. Instead of using the special status and read ID command codes (which require to read status/ID from special registers instead of the regular data area) the driver now now uses the main data buffer for all commands. This simplifies the driver as no special casing is needed. For control data (status byte, id bytes and parameter page) the driver needs to reverse byte order for little endian CPUs since the controller seems to store the bytes in big endian order in the data buffer. The current state seems to pass MTD tests on a Colibri VF61.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
