How to setup vana-supply and vif-supply in AGX Orin NX?

I had setup the tegra234-p3701-0004-p3737-0000.dts device tree of ar0234 camera sensor driver on AGX Orin.

ar0234_a@43 { 
	status = "okay";
	compatible = "nvidia,ar0234";
	reg = <0x43>;
	sensor_model ="ar0234";
	avdd-reg = "vana";
	iovdd-reg = "vif";

	vana-supply = <&p3737_avdd_cam_2v8>;
	vif-supply = <&p3737_vdd_1v8_sys>;
}

I try to move this device tree setting to tegra234-p3767-0000-p3768-0000-a0.dts on AGX Orin NX, but it can’t find p3737_avdd_cam_2v8 and p3737_vdd_1v8_sys on AGX Orin NX.

vana-supply = <&p3737_avdd_cam_2v8>;
vif-supply = <&p3737_vdd_1v8_sys>;

hello sammyb7qw7,

please help me double confirm the platform you’re working with.
is it AGX Orin, or Orin NX?

BTW,
there’s fix regulator, tegra234-p3737-fixed-regulator.dtsi to define 2v8 regulator settings.

I am working on the Orin NX now.
I could find the p3768_vdd_1v8, but Why I can’t find the p3768_avdd_2v8 in tegra234-p3768-0000-a0-fixed-regulator.dtsi?

vana-supply = <&p3737_avdd_cam_2v8>;
vif-supply = <&p3768_vdd_1v8>;

hello sammyb7qw7,

I’ve also checked with internal team, there is no 2v8 signal on Orin NX. it should provided by sensor board.
