Hi Stephen, again
Can I confirm ??
Was I misunderstanding ??

------ Pattern1 -----------
sound_soc {
clocks = <&xxx>, <&xxx>;
clock-names = "cpu", "codec";
...
cpu { /* of_cpu_node */
...
};
codec { /* of_codec_node */
...
};
};
----------------------------
Do you mean, this case we can use
devm_get_clk_from_child(dev, of_cpu_node, "cpu");
devm_get_clk_from_child(dev, of_codec_node, "codec");
------ Pattern2 -----------
sound_soc {
...
cpu { /* of_cpu_node */
clocks = <&xxx>;
...
};
codec { /* of_codec_node */
clocks = <&xxx>;
...
};
};
----------------------------
And, this case, we can use
devm_get_clk_from_child(dev, of_cpu_node, NULL);
devm_get_clk_from_child(dev, of_codec_node, NULL);
If so, I can use it without DT change.
