Hm? Why? The placement is after compatible.

Nothing improved here. I already commented about above and this.
Implement feedback for all your patches, not only one.

Sorry about that.
I saw you say "Broken alignment" in v15 patch.
Would like to ask if the following format meets your expectations?
+			gpio-line-names =
+				"P48V_OCP_GPIO1", "P48V_OCP_GPIO2",
+				"P48V_OCP_GPIO3", "FAN_BOARD_0_REVISION_0_R",

Please read DTS coding style before posting next version of the patch
(or any patch for DTS). This is still not aligned. There is (almost)
never a blank line after '='.

Best regards,
Krzysztof

Hi Krzysztof,
After checking the DTS coding style, I found the "Indentation" section mentioned that:
"For arrays spanning across lines, it is preferred to align the continued entries with opening < from the first line."

Should I align the code with following format? (No blank line after = and use two space to align the ")
Or would like to ask could you help to provide the dts file that I can follow?

gpio-line-names = "HSC1_ALERT1_R_N", "HSC2_ALERT1_R_N",
				  "HSC3_ALERT1_R_N", "HSC4_ALERT1_R_N",
				  "HSC5_ALERT1_R_N", "HSC6_ALERT1_R_N",
				  "HSC7_ALERT1_R_N", "HSC8_ALERT1_R_N",
				  "HSC1_ALERT2_R_N", "HSC2_ALERT2_R_N",
				  "HSC3_ALERT2_R_N", "HSC4_ALERT2_R_N",
				  "HSC5_ALERT2_R_N", "HSC6_ALERT2_R_N",
				  "HSC7_ALERT2_R_N", "HSC8_ALERT2_R_N";
Thanks.

Sure, e.g. qcom/sm8650.dtsi, line 765 or line 796.

Or arch/arm64/boot/dts/qcom/sm8450-sony-xperia-nagara.dtsi and
gpio-line-names.

Best regards,
Krzysztof

Thanks for your help!
I'll correct the format in v2.
