Starting from [1], the series fixes the timings setting of the gpmi controller for the mx28 architecture, also adding support for fast edo mode timings. The whole series has been heavily tested with the mtd kernel test modules, and with repeated write cycles on nand. [1] https://lore.kernel.org/r/20210702065350.209646-5-ebiggers@xxxxxxxxxx Changes in v2: - Reparent by device tree instead of code (drivers/clk/mxs/clk-imx28.c). Suggested by Stephen Boyd. - Improve the commit description. - give examples of frequencies on my setup. - Add the patch to the series. - Fix commit description. - Add an example to the commit description to better understand the problem solved by the patch. - Split the patch. - Improve the commit message. - Move the patch to the end of the series.
