Manual focus driver

[Orinbeginner_xyz]

Hi authors.

I have a question for focuser driver.

module: Jetson orin nano 8GB (P3767-0005)
carrier board : Jetson orin nano dev kit(P3768-0000)
Camera: raspberry pi cam V3
Jetson Linux:R35.4.1

I am trying to write a manual “dw9817” focus driver based on nv_lc898212.c focus driver.
And no error occurred compiled my dw9817.c driver.
After I modified my Device Tree setting dw9817 as a i2c device. (as shown below)

~~
port@0 {
	reg = <0>;
	rbpcv3_imx708_out0: endpoint {
		port-index = <0>;
		bus-width = <2>;
		remote-endpoint = <&rbpcv3_imx708_csi_in0>;
	};
};
};
};

imx708_lens0: lens_imx708_a@0c {
compatible = "dongwoon,dw9817vcm";
reg = <0x0c>;

min_focus_distance = "0.0";		
hyper_focal = "0.0";
focal_length = "3.04";
f_number = "2.0";
aperture = "0.0";
};

~~

modules {
			cam0_module0:module0 {
				badge = "jakku_front_RBPCV3";
				position = "front";
				orientation = "1";
				cam0_module0_drivernode0:drivernode0 {
					pcl_id = "v4l2_sensor";
					devname = "imx708 9-001a";
					proc-device-tree = "/proc/device-tree/cam_i2cmux/i2c@0/rbpcv3_imx708_a@1a";
				};
				cam_module0_drivernode1: drivernode1 {
					pcl_id = "v4l2_lens";
					devname = "dw9817vcm 9-001c";
					proc-device-tree = "/proc/device-tree/cam_i2cmux/i2c@0/lens_imx708_a@0c/";
				};
~~

But I added 2 new ioctl (V4L2_CID_FOCUS_ABSOLUTE, TEGRA_CAMERA_CID_FOCUS_SYNC_EXTERNAL), those didn’t reflect V4l2 controler. (Insmod dw9817 driver is success.)

What do you think could be the reason for this?

Sorry to tell Jetson current don’t support FOCUS.

Thanks
