[PATCH v4 16/16] arm64: dts: allwinner: h616: add NAND controller

Richard Genoud
2025-10-28T07:36:36Z

The H616 has a NAND controller quite similar to the A10/A23 ones, but
with some register differences, more clocks (for ECC and MBUS), more ECC
strengths, so this requires a new compatible string.

Add the NAND controller node and pins in the device tree.
