+Socionext UniPhier SoC family
+-----------------------------
+
+Required properties in the root node:
+  - compatible: should contain board and SoC compatible strings
+
+SoC and board compatible strings:
+  (sorted chronologically)
+
+  - LD4 SoC:  "socionext,uniphier-ld4"
+      - Reference Board: "socionext,uniphier-ld4-ref"
+
+  - Pro4 SoC: "socionext,uniphier-pro4"
+      - Reference Board: "socionext,uniphier-pro4-ref"
+      - Ace Board:       "socionext,uniphier-pro4-ace"
+      - Sanji Board:     "socionext,uniphier-pro4-sanji"
+
+  - sLD8 SoC: "socionext,uniphier-sld8"
+      - Reference Board: "socionext,uniphier-sld8-ref"
+
+  - PXs2 SoC: "socionext,uniphier-pxs2"
+      - Gentil Board:    "socionext,uniphier-pxs2-gentil"
