1Mediatek AFE PCM controller for mt8183
2
3Required properties:
4- compatible = "mediatek,mt68183-audio";
5- reg: register location and size
6- interrupts: should contain AFE interrupt
7- resets: Must contain an entry for each entry in reset-names
8  See ../reset/reset.txt for details.
9- reset-names: should have these reset names:
10		"audiosys";
11- power-domains: should define the power domain
12- clocks: Must contain an entry for each entry in clock-names
13- clock-names: should have these clock names:
14		"infra_sys_audio_clk",
15		"mtkaif_26m_clk",
16		"top_mux_audio",
17		"top_mux_aud_intbus",
18		"top_sys_pll3_d4",
19		"top_clk26m_clk";
