Mediatek AFE PCM controller



Required properties:

- compatible = "mediatek,mt8173-afe-pcm";

- reg: register location and size

- interrupts: Should contain AFE interrupt

- clock-names: should have these clock names:

		"infra_sys_audio_clk",

		"top_pdn_audio",

		"top_pdn_aud_intbus",

		"bck0",

		"bck1",

		"i2s0_m",

		"i2s1_m",

		"i2s2_m",

		"i2s3_m",

		"i2s3_b";



Example:



	afe: mt8173-afe-pcm@11220000  {

		compatible = "mediatek,mt8173-afe-pcm";

		reg = <0 0x11220000 0 0x1000>;

		interrupts = <GIC_SPI 134 IRQ_TYPE_EDGE_FALLING>;

		clocks = <&infracfg INFRA_AUDIO>,

			<&topckgen TOP_AUDIO_SEL>,

			<&topckgen TOP_AUD_INTBUS_SEL>,

			<&topckgen TOP_APLL1_DIV0>,

			<&topckgen TOP_APLL2_DIV0>,

			<&topckgen TOP_I2S0_M_CK_SEL>,

			<&topckgen TOP_I2S1_M_CK_SEL>,

			<&topckgen TOP_I2S2_M_CK_SEL>,

			<&topckgen TOP_I2S3_M_CK_SEL>,

			<&topckgen TOP_I2S3_B_CK_SEL>;

		clock-names = "infra_sys_audio_clk",

				"top_pdn_audio",

				"top_pdn_aud_intbus",

				"bck0",

				"bck1",

				"i2s0_m",

				"i2s1_m",

				"i2s2_m",

				"i2s3_m",

				"i2s3_b";
