Merge tag 'nand/for-6.14' into mtd/next

* Raw NAND changes

A new controller driver, from Nuvoton, has been merged.

Bastien Curutchet has contributed a series improving the Davinci
controller driver, both on the organization of the code, but also on the
performance side. The binding has also been converted to yaml, received
a new OOB layout and now supports on-die ECC engines.

The Qualcomm controller driver has been deeply cleaned to extract some
parts of the code into a shared file with the Qualcomm SPI memory
controller.

Aside from these main changes, the Cadence binding has been converted to
yaml, the brcmnand controller driver has received a small fix, otherwise
some more minor changes have also made their way in.

* SPI NAND changes

The SPI NAND subsystem has seen a great improvement, with the advent of
DTR operations (DDR operations, which may be extended to the address
cycles). The first vendor driver to benefit from these improvements is
the Winbond driver.

A new manufacturer driver is added SkyHigh, with a new constraint for
the core, it is impossible to disable the on-die ECC engine.

A Foresee device is also now supported.
