 Required properties:
-- compatible: Should be "mrvl,pxav2-mmc" or "mrvl,pxav3-mmc".
+- compatible: Should be "mrvl,pxav2-mmc", "mrvl,pxav3-mmc" or
+  "marvell,armada-380-sdhci".
+- reg:
+  * for "mrvl,pxav2-mmc" and "mrvl,pxav3-mmc", one register area for
+    the SDHCI registers.
+
+  * for "marvell,armada-380-sdhci", three register areas. The first
+    one for the SDHCI registers themselves, the second one for the
+    AXI/Mbus bridge registers of the SDHCI unit, the third one for the
+    SDIO3 Configuration register
+- reg names: should be "sdhci", "mbus", "conf-sdio3". only mandatory
+  for "marvell,armada-380-sdhci"
+- clocks: Array of clocks required for SDHCI; requires at least one for
+    I/O clock.
+- clock-names: Array of names corresponding to clocks property; shall be
+    "io" for I/O clock and "core" for optional core clock.
 
 Optional properties:
