+Renesas R-Car sound
+
+Required properties:
+- compatible			: "renesas,rcar_sound-gen1" if generation1
+				  "renesas,rcar_sound-gen2" if generation2
+- reg				: Should contain the register physical address.
+				  required register is
+				   SRU/ADG/SSI      if generation1
+				   SRU/ADG/SSIU/SSI if generation2
+- rcar_sound,ssi		: SSI subnode
+- rcar_sound,scu		: SCU subnode
+- rcar_sound,dai		: DAI subnode
+
+SSI subnode properties:
+- interrupt-parent		: Should contain SSI interrup parent
+- interrupts			: Should contain SSI interrupt for PIO transfer
+- shared-pin			: if shared clock pin
+
+DAI subnode properties:
+- playback			: list of playback modules
+- capture			: list of capture  modules
