+==============================================================================
+
+Required properties:
+- compatible: should be "st,stih407-hva".
+- reg: HVA physical address location and length, esram address location and
+  length.
+- reg-names: names of the registers listed in registers property in the same
+  order.
+- interrupts: HVA interrupt number.
+- clocks: from common clock binding: handle hardware IP needed clocks, the
+  number of clocks may depend on the SoC type.
+  See ../clock/clock-bindings.txt for details.
+- clock-names: names of the clocks listed in clocks property in the same order.
+
+Example:
+
+hva@8c85000{
+	compatible = "st,stih407-hva";
+	reg= <0x8c85000 0x400>, <0x6000000 0x40000>;
+	reg-names = "hva_registers", "hva_esram";
+	interrupts = <0 58 0>, <0 59 0>;
+	clock-names = "clk_hva";
+	clocks = <&CLK_S_C0_FLEXGEN 3>;
+};
