[PATCH v2 0/3] Renesas RZ/N1 NAND controller support

[Miquel Raynal]

Hello,

Here is a short series bringing support for Renesas RZ/N1 NAND
controller.

So far this driver has been tested with a not-fully-upstream device tree
because clock tree is not yet described entirely, I am going to work on
it really soon but I believe we don't need full clock support to get the
NAND controller driver merged for now.

Cheers,
Miquèl

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.
