Mediatek AFE PCM controller for mt8183
2
+
3
+
Required properties:
4
+
- compatible = "mediatek,mt68183-audio";
5
+
- reg: register location and size
6
+
- interrupts: should contain AFE interrupt
7
+
- power-domains: should define the power domain
8
+
- clocks: Must contain an entry for each entry in clock-names
9
+
- clock-names: should have these clock names:
10
+
"infra_sys_audio_clk",
11
+
"mtkaif_26m_clk",
12
+
"top_mux_audio",
13
+
"top_mux_aud_intbus",
14
+
"top_sys_pll3_d4",
15
+
"top_clk26m_clk";
