+Renesas FSI
+
+Required properties:
+- compatible : "renesas,sh_fsi2" or "renesas,sh_fsi"
+- reg : Should contain the register physical address and length
+- interrupts : Should contain FSI interrupt
+
+- fsia,spdif-connection : FSI is connected by S/PDFI
+- fsia,stream-mode-support : FSI supports 16bit stream mode.
+- fsia,use-internal-clock : FSI uses internal clock when master mode.
+
+- fsib,spdif-connection : same as fsia
+- fsib,stream-mode-support : same as fsia
+- fsib,use-internal-clock : same as fsia
+
+Example:
+
+sh_fsi2: sh_fsi2@0xec230000 {
+ compatible = "renesas,sh_fsi2";
+ reg = <0xec230000 0x400>;
+ interrupts = <0 146 0x4>;
+
+ fsia,spdif-connection;
+ fsia,stream-mode-support;
