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 v4:
* Set unevaluatedProperties set to false in the bindings.
* Change the clock names by removing the nand_ prefix which is
redundant, even though the clocks are named like this in the spec. The
name remains clear enough anyway.
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.
