Why is the pinctrl-1 still here?

while reading your patch I also noticed that you had to specify these
cells here. 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.

Thanks you,
  Marco

Thanks for your comments!
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?

You're right, not sure why I didn't saw it in the first place.
