pinmux/pinctrl collision migrating from 5.10 to 6.12

General Discussion

I have a device that is claiming the pins that my overlay uses, but am unsure how to resolve the collision. This particular collision is with the cpsw, I think. I tried setting the status of cpsw_port1 and ethernet0 to “disabled”. The former had no immediate effect, and the second one caused boot errors. This is what I currently have,

&cpsw_port1 {
  status = "disabled";
};

  camera_pins: camera_pins {
    #gpio-cells = <2>;

This is the error.

[   29.547194] pinctrl-single 44e10800.pinmux: pin PIN71 already requested by 4a100000.switch; cannot claim for prudev

Those pins you are fighting are not in cpsw_port1 but mac_sw

&mac_sw {
	pinctrl-names = "default", "sleep";
	pinctrl-0 = <&cpsw_default>;
	pinctrl-1 = <&cpsw_sleep>;
	status = "okay";
};
