It is very common to specify it within the base dtsi file imx93.dtsi. Can you please provde an extra patch which adds this to the base dtsi followed by this patch, which of course do need to specify it again.

Have checked the base dtsi file imx93.dtsi. The these cells already existed. The current cells is same with the lpi2c3 node in imx93.dtsi. So should remove these cells in order to keep terse?
