Hi Tzung-Bi, "mediatek,headset-codec" is a child node of pdev->dev.of_node, so I use of_get_child_by_name() to get and pass it to snd_soc_of_get_dai_link_codecs(). Jiaxin.Yu Thanks

"mediatek,platform" and "mediatek,hdmi-codec" are also children of pdev->dev.of_node. I guess my question is: why doesn't it also use of_parse_phandle() for "mediatek,headset-codec"? Did I misunderstand?

Hi Tzung-Bi, The following is from bindings, "mediatek,speaker-codec" and "mediatek,headset-codec" are sub nodes of sound but "mediatek,platform" and "mediatek,hdmi-codec" are the name of properties. So we can't get the sub node pointer through of_parse_phandle(). sound: mt8192-sound { compatible = "mediatek,mt8192_mt6359_rt1015_rt5682"; mediatek,platform = <&afe>; mediatek,hdmi-codec = <&anx_bridge_dp>; pinctrl-names = "aud_clk_mosi_off", "aud_clk_mosi_on"; pinctrl-0 = <&aud_clk_mosi_off>; pinctrl-1 = <&aud_clk_mosi_on>; mediatek,headset-codec { sound-dai = <&rt5682>; }; mediatek,speaker-codec { sound-dai = <&rt1015_l>, <&rt1015_r>; }; };

Will provide my R-b tag in another thread.
