From b01a731a4a5e3e8b6bc53ed80dbc6f69c42cb6d2 Mon Sep 17 00:00:00 2001 From: Frank Li Date: Wed, 16 Oct 2024 16:31:12 -0400 Subject: [PATCH] dt-bindings: memory: fsl: Add compatible string nxp,imx9-memory-controller iMX9 memory controller is similar with other layerscape chips. But some register layout has a little bit difference, so add new compatible string 'nxp,imx9-memory-controller' for it. imx9 need two 'reg', one for DDR controller and the other is ECC inject engine register space. Keep the same restriction for other compatible string.
