+Mediatek AFE PCM controller for mt8516
+
+Required properties:
+- compatible:  "mediatek,mt8516-audio"
+- interrupts: should contain AFE interrupt
+- clocks: Must contain an entry for each entry in clock-names
+- clock-names: should have these clock names:
+		"top_pdn_audio",
+		"aud_dac_clk",
+		"aud_dac_predis_clk",
+		"aud_adc_clk";
+
+Example:
+
+
+	afe: mt8516-afe-pcm@...40000  {
+		compatible = "mediatek,mt8516-audio";
+		reg = <0 0x11140000 0 0x1000>;
+		interrupts = <GIC_SPI 120 IRQ_TYPE_LEVEL_LOW>;
+		clocks = <&topckgen CLK_TOP_AUDIO>,
+			 <&audiotop CLK_AUD_DAC>,
+			 <&audiotop CLK_AUD_DAC_PREDIS>,
+			 <&audiotop CLK_AUD_ADC>;
+		clock-names = "top_pdn_audio",
+			      "aud_dac_clk",
+			      "aud_dac_predis_clk",
+			      "aud_adc_clk";
+	};
