Mediatek AFE PCM controller for mt8183
Required properties:
- compatible = "mediatek,mt68183-audio";
- reg: register location and size
- interrupts: should contain AFE interrupt
- resets: Must contain an entry for each entry in reset-names
See ../reset/reset.txt for details.
- reset-names: should have these reset names:
"audiosys";
- power-domains: should define the power domain
- clocks: Must contain an entry for each entry in clock-names
- clock-names: should have these clock names:
"infra_sys_audio_clk",
"mtkaif_26m_clk",
"top_mux_audio",
"top_mux_aud_intbus",
"top_sys_pll3_d4",
"top_clk26m_clk";
Example:
afe: mt8183-afe-pcm@11220000 {
compatible = "mediatek,mt8183-audio";
reg = <0 0x11220000 0 0x1000>;
interrupts = <GIC_SPI 161 IRQ_TYPE_LEVEL_LOW>;
resets = <&watchdog MT8183_TOPRGU_AUDIO_SW_RST>;
reset-names = "audiosys";
power-domains = <&scpsys MT8183_POWER_DOMAIN_AUDIO>;
clocks = <&infrasys CLK_INFRA_AUDIO>,
<&infrasys CLK_INFRA_AUDIO_26M_BCLK>,
<&topckgen CLK_TOP_MUX_AUDIO>,
<&topckgen CLK_TOP_MUX_AUD_INTBUS>,
<&topckgen CLK_TOP_SYSPLL_D2_D4>,
<&clk26m>;
clock-names = "infra_sys_audio_clk",
"mtkaif_26m_clk",
"top_mux_audio",
"top_mux_aud_intbus",
"top_sys_pll_d2_d4",
"top_clk26m_clk";
};
