+Mediatek AFE PCM controller for mt8183
+
+Required properties:
+- compatible = "mediatek,mt68183-audio";
+- reg: register location and size
+- interrupts: should contain AFE interrupt
+- resets: Must contain an entry for each entry in reset-names
+ See ../reset/reset.txt for details.
+- reset-names: should have these reset names:
+ "audiosys";
+- power-domains: should define the power domain
+- clocks: Must contain an entry for each entry in clock-names
+- clock-names: should have these clock names:
+ "infra_sys_audio_clk",
+ "mtkaif_26m_clk",
+ "top_mux_audio",
+ "top_mux_aud_intbus",
+ "top_sys_pll3_d4",
+ "top_clk26m_clk";
+
+Example:
