1Mediatek AFE PCM controller for mt6797
2
3Required properties:
4- compatible = "mediatek,mt6797-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		"infra_sys_audio_26m",
12		"mtkaif_26m_clk",
13		"top_mux_audio",
14		"top_mux_aud_intbus",
15		"top_sys_pll3_d4",
16		"top_sys_pll1_d4",
17		"top_clk26m_clk";
