[PATCH 0/3] Add Renesas RZ/N1x EDAC driver

From: Paul Louvel

Date: Thu Sep 24 2026 - 05:33:30 EST


The Cadence memory controller found on Renesas RZ/N1x SoCs supports ECC
with SECDED.

The memory controller found on the r9a06g032 supports at most a single
DIMM of DDR2/3, up to 2GB.

Add the EDAC driver for this memory controller, and the relevant
device-tree binding. Also add the EDAC node to the existing r9a06g032
SoC base device-tree.
