Commit Message

Add devicetree bindings documentation file for rt5514 spi dsp codec.

Also update rt5514 i2c dt-binding's compatible to distinguish it from
rt5514 spi.

+RT5514 SPI audio CODEC
+
+This device supports SPI only.
+
+Required properties:
+
+- compatible : "realtek,rt5514" or "realtek,rt5514", "realtek,rt5514-spi".
+
+- reg : The SPI address of the device.
+
+Optional properties:
+
+- interrupt-parent: Should be the phandle for the interrupt controller
+- interrupts: The interrupt number to the cpu. The interrupt specifier format
+	      depends on the interrupt controller.
+
+Example:
+
+codec: rt5514-spi@0 {
+	compatible = "realtek,rt5514", "realtek,rt5514-spi";
+	reg = <0>;
+
+	pinctrl-names = "default";
+	pinctrl-0 = <&mic_int>;
+
+	interrupt-parent = <&gpio1>;
+	interrupts = <13 IRQ_TYPE_LEVEL_HIGH>;
+	wakeup-source;
+};
