After a nand_reset_data_interface(), both the NAND chip and the NAND controller use timing mode 0. The previously defined data interface for this chip has been saved and is supposed to be restored after that. However, if the saved data interface also refers to timing mode 0, there is no need to re-apply them again. Also, as nand_setup_data_interface() uses ->set/get_features(), it could lead to issues when doing the reset at probe time as the parameter page is not available yet to know if these functions are supported or not.

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.
