-Device-tree bindings for AST2600 FSI master
--------------------------------------------
-
-The AST2600 contains two identical FSI masters. They share a clock and have a
-separate interrupt line and output pins.
-
-Required properties:
- - compatible: "aspeed,ast2600-fsi-master"
- - reg: base address and length
- - clocks: phandle and clock number
- - interrupts: platform dependent interrupt description
- - pinctrl-0: phandle to pinctrl node
- - pinctrl-names: pinctrl state
-
-Optional properties:
- - cfam-reset-gpios: GPIO for CFAM reset
-
- - fsi-routing-gpios: GPIO for setting the FSI mux (internal or cabled)
- - fsi-mux-gpios: GPIO for detecting the desired FSI mux state
-
-
-Examples:
-
-    fsi-master {
-        compatible = "aspeed,ast2600-fsi-master", "fsi-master";
-        reg = <0x1e79b000 0x94>;
-	interrupts = <GIC_SPI 100 IRQ_TYPE_LEVEL_HIGH>;
-	pinctrl-names = "default";
-	pinctrl-0 = <&pinctrl_fsi1_default>;
-	clocks = <&syscon ASPEED_CLK_GATE_FSICLK>;
-
-	fsi-routing-gpios = <&gpio0 ASPEED_GPIO(Q, 7) GPIO_ACTIVE_HIGH>;
-	fsi-mux-gpios = <&gpio0 ASPEED_GPIO(B, 0) GPIO_ACTIVE_HIGH>;
-
-	cfam-reset-gpios = <&gpio0 ASPEED_GPIO(Q, 0) GPIO_ACTIVE_LOW>;
-    };
