 * Serial NOR flash controller for MTK MT81xx (and similar)
 
 Required properties:
-- compatible:    The possible values are:
-                 "mediatek,mt2701-nor"
-                 "mediatek,mt7623-nor"
+- compatible:    For mt8173, compatible should be "mediatek,mt8173-nor",
+                 and it's the fallback compatible for other Soc.
+                 For every other SoC, should contain both the SoC-specific compatible
+                 string and "mediatek,mt8173-nor".
+                 The possible values are:
+                 "mediatek,mt2701-nor", "mediatek,mt8173-nor"
+                 "mediatek,mt2712-nor", "mediatek,mt8173-nor"
+                 "mediatek,mt7622-nor", "mediatek,mt8173-nor"
+                 "mediatek,mt7623-nor", "mediatek,mt8173-nor"
                  "mediatek,mt8173-nor"
-                 For mt8173, compatible should be "mediatek,mt8173-nor".
-                 For every other SoC, should contain both the SoC-specific compatible string
-                 and "mediatek,mt8173-nor".
 - reg:                   physical base address and length of the controller's register
 - clocks:        the phandle of the clocks needed by the nor controller
 - clock-names:           the names of the clocks
