 * Serial NOR flash controller for MTK MT81xx (and similar)
 
 Required properties:
-- compatible: 	  should be "mediatek,mt8173-nor";
+- compatible: 	  The possible values are:
+		  "mediatek,mt2701-nor"
+		  "mediatek,mt7623-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
