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",
