+Mediatek AFE PCM controller for mt8183
+
+Required properties:
+- compatible = "mediatek,mt68183-audio";
+- reg: register location and size
+- interrupts: should contain AFE interrupt
+- 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:
+
+ afe: mt8183-afe-pcm@11220000 {
+ compatible = "mediatek,mt8183-audio";
+ reg = <0 0x11220000 0 0x1000>;
+ interrupts = <GIC_SPI 161 IRQ_TYPE_LEVEL_LOW>;
+ power-domains = <&scpsys MT8183_POWER_DOMAIN_AUDIO>;
+ clocks = <&infrasys CLK_INFRA_AUDIO>,
+ <&infrasys CLK_INFRA_AUDIO_26M_BCLK>,
+ <&topckgen CLK_TOP_MUX_AUDIO>,
+ <&topckgen CLK_TOP_MUX_AUD_INTBUS>,
+ <&topckgen CLK_TOP_SYSPLL_D2_D4>,
+ <&clk26m>;
+ clock-names = "infra_sys_audio_clk",
+ "mtkaif_26m_clk",
+ "top_mux_audio",
+ "top_mux_aud_intbus",
+ "top_sys_pll_d2_d4",
+ "top_clk26m_clk";
