charset="utf-8" From: Lad Prabhakar On HiHope boards, the audio configuration uses a single port with one endpoint, defined as: rsnd_port: port { rsnd_endpoint: endpoint { remote-endpoint =3D <&dw_hdmi0_snd_in>; dai-format =3D "i2s"; bitclock-master =3D <&rsnd_endpoint>; frame-master =3D <&rsnd_endpoint>; playback =3D <&ssi2>; }; }; Commit 547b02f74e4a ("ASoC: rsnd: enable multi Component support for Audio Graph Card/Card2") added support for multiple ports. This caused probe failures on HiHope boards because the device node pointers used to retrieve the endpoint were incorrect. This patch resolves the issue by introducing a new helper function, `rsnd_pick_endpoint_node_for_ports()`, which retrieves the correct device node pointer by checking if the port is named 'port' or 'ports'. The `rsnd_dai_of_node()` and `rsnd_dai_probe()` functions are updated to use this helper, ensuring proper endpoint parsing in both single-port and multi-port configurations. This restores compatibility with HiHope boards.
