Until now the GPMI driver had its own timings logic while the core already handles that and request the NAND controller drivers to support the ->setup_data_interface() hook. Implement that hook by reusing the already existing function. No real glue is necessary between core timing delays and GPMI registers because the driver already translates the ONFI timing modes into register values. Make use of the core's tREA, tRLOH and tRHOH values that allow computing more precise timings for mode [0-3] and get significantly better values (+20% with an i.MX6 Sabre Auto board). Otherwise use the existing logic. Signed-off-by: Miquel Raynal <miquel.raynal@bootlin.com> Tested-by: Han Xu <han.xu@nxp.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.
