Usually, the source of the error when setting/getting features does not matter (if the controller does not support sending the command or if the chip does not support the operation). When it comes to timings, if the controller fails it is an error while if the chip does not support the operation, it can be silently supposed that it already works with the maximum supported timings. Introduce some logic in nand_setup_data_interface() to handle that difference. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Signed-off-by: Boris Brezillon <boris.brezillon@bootlin.com>
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.
