Hello, Here is a short series bringing support for Renesas RZ/N1 NAND controller. This time the driver has been tested with a fully-upstream device tree on top of a v5.16-rc4. The DT used is very close to the r9a06g032-db. Cheers, Miquèl Changes in v3: * Rebased on top of a fully-upstream recent kernel. * Renamed the clocks in the bindings and the driver to match the documentation (lower-cased): nand_hclk & nand_eclk. * Added a new commit describing the NAND controller in the r9a06g032 DTSI. * Added the Reviewed-by and Tested-by tags received. Changes in v2: * Added the family-specific rzn1 compatible as suggested by Geert. Updated the bindings, the binding file name, the compatible used in the driver, the MAINTAINERS entry, etc. * Added an ARCH_RENESAS Kconfig dependency. * Changed the type (to unsigned) of a couple of variables. * Returned earlier when possible to reduce indentation. * Used platform_get_irq_optional() instead of platform_get_irq() to avoid a useless warning. * Handled probe deferral correctly. * Applied a massive s/nfc/nandc/ as suggested by Geert to avoid confusions with the near-field-communication device. * Mentioned Evatronix as original authors of the IP in the commit log and in the header. * Added an additional check on the validity of the child nodes reg property. * A couple of style fixes.
