Required properties:
- compatible = "mediatek,mt2701-audio";
-- reg: register location and size
- interrupts: should contain AFE and ASYS interrupts
- interrupt-names: should be "afe" and "asys"
- power-domains: should define the power domain
- clocks: Must contain an entry for each entry in clock-names
See ../clocks/clock-bindings.txt for details
- clock-names: should have these clock names:
+ "infra_sys_audio_clk",
"top_audio_mux1_sel",
"top_audio_mux2_sel",
+ "top_audio_a1sys_hp",
+ "top_audio_a2sys_hp",
"i2s0_src_sel",
"i2s1_src_sel",
"i2s2_src_sel",
- assigned-clocks-parents: parent of input clocks of assigned clocks.
- assigned-clock-rates: list of clock frequencies of assigned clocks.
+Must be a subnode of MediaTek audsys device tree node.
+See ../arm/mediatek/mediatek,audsys.txt for details about the parent node.
