-Renesas FSI
-
-Required properties:
-- compatible			: "renesas,fsi2-<soctype>",
-				  "renesas,sh_fsi2" or "renesas,sh_fsi" as
-				  fallback.
-				  Examples with soctypes are:
-				    - "renesas,fsi2-r8a7740" (R-Mobile A1)
-				    - "renesas,fsi2-sh73a0" (SH-Mobile AG5)
-- reg				: Should contain the register physical address and length
-- interrupts			: Should contain FSI interrupt
-
-- fsia,spdif-connection		: FSI is connected by S/PDIF
-- 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@ec230000 {
-	compatible = "renesas,sh_fsi2";
-	reg = <0xec230000 0x400>;
-	interrupts = <0 146 0x4>;
-
-	fsia,spdif-connection;
-	fsia,stream-mode-support;
-	fsia,use-internal-clock;
-};
