[PATCH v2 0/2] M5441x: Add NFC support

From: Jean-Michel Hautbois
Date: Thu Jun 27 2024 - 12:06:09 EST


The M5441x has the same NFC IP as the VF610. It does not support
device-tree, so a few changes are needed in particular at probe time.

A new variant is also needed as the Reference Manual states that the
NFC_ROW_ADDR does not drive CS.

Tested on a custom board with a Micron RAW nand.
