Getting the OV5640 camera to work under armbian with kernel 5.8

Banana Pi SBCs design BPI-M64(A64)
1

I am still trying to get my ov5640 camera to work on my M64. I recompiled kernel 5.8.16-sunxi64 to include the ov5640 kernel module and I included that module in the initramfs. I also updated the sun50i-a64-bananapi-m64.dts file by copying and adjusting the camera overlay code from sun50i-a64-pinetab.dts, but it is not working.

gollumm64% v4l2-ctl --list-devices
cedrus (platform:cedrus):
        /dev/video0
        /dev/media0

gollumm64% v4l2-ctl -d 0 --list-formats --list-ctrls

This is the dts code I added to sun50i-a64-bananapi-m64.dts:

	i2c-csi {
		compatible = "i2c-gpio";
		sda-gpios = <&pio 4 13 GPIO_ACTIVE_HIGH>; /* PE13 */
		scl-gpios = <&pio 4 12 GPIO_ACTIVE_HIGH>; /* PE12 */
		i2c-gpio,delay-us = <5>;
		#address-cells = <1>;
		#size-cells = <0>;

		ov5640: camera@3c {
			compatible = "ovti,ov5640";
			reg = <0x3c>;
			pinctrl-names = "default";
			pinctrl-0 = <&csi_mclk_pin>;
			clocks = <&ccu CLK_CSI_MCLK>;
			clock-names = "xclk";

			AVDD-supply = <&reg_dldo3>;
			DOVDD-supply = <&reg_aldo1>;
			DVDD-supply = <&reg_eldo3>;
			reset-gpios = <&pio 4 16 GPIO_ACTIVE_LOW>; /* PE16 */
			powerdown-gpios = <&pio 4 17 GPIO_ACTIVE_HIGH>; /* PE17 */

			port {
				ov5640_ep: endpoint {
					remote-endpoint = <&csi_ep>;
					bus-width = <8>;
					hsync-active = <1>; /* Active high */
					vsync-active = <0>; /* Active low */
					data-active = <1>;  /* Active high */
					pclk-sample = <1>;  /* Rising */
				};
			};
		};
	};

&csi {
	status = "okay";

	port {
		#address-cells = <1>;
		#size-cells = <0>;

		csi_ep: endpoint {
			remote-endpoint = <&ov5640_ep>;
			bus-width = <8>;
			hsync-active = <1>; /* Active high */
			vsync-active = <0>; /* Active low */
			data-active = <1>;  /* Active high */
			pclk-sample = <1>;  /* Rising */
		};
	};
};

What am I missing?
