First off, thanks to everyone who has figured this all out. Much of this is over my head I think I've nearly got my camera working with Armbian 22.08.6 Jammy on Linux 5.15.69-sunxi which is running on an Orange Pi PC. I've gotten /dev/media1 and /dev/video1 nodes after using the following device tree overlay. It is just a combination of @rreignier's overlay with @gsumner's regulator nodes but I haven't seen anyone post a combined overlay yet so I hope this makes it clear for anyone trying to get this to work on the same platform. /dts-v1/; /plugin/; / { compatible = "allwinner,sun8i-h3"; }; &ccu { assigned-clocks = <&ccu 107>; assigned-clock-parents = <&osc24M>; assigned-clock-rates = <24000000>; }; &pio { csi_mclk_pin: csi-mclk-pin { pins = "PE1"; function = "csi"; }; }; &i2c2_pins { bias-pull-up; }; &i2c2 { status = "okay"; ov5640: camera@3c { compatible = "ovti,ov5640"; reg = <0x3c>; pinctrl-names = "default"; pinctrl-0 = <&csi_mclk_pin>; clocks = <&ccu 107>; clock-names = "xclk"; AVDD-supply = <&reg_vcc_af_csi>; DOVDD-supply = <&reg_vdd_1v5_csi>; DVDD-supply = <&reg_vcc_csi>; reset-gpios = <&pio 4 14 1>; /* CSI-RST-R: PE14 */ powerdown-gpios = <&pio 4 15 0>; /* CSI-STBY-R: PE15 */ port { ov5640_ep: endpoint { remote-endpoint = <&csi_ep>; bus-width = <8>; data-shift = <2>; /* lines 9:2 are used */ 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 */ }; }; }; &{/} { reg_vdd_1v5_csi: vdd-1v5-csi { compatible = "regulator-fixed"; regulator-name = "vdd1v5-csi"; regulator-min-microvolt = <1500000>; regulator-max-microvolt = <1500000>; gpio = <&pio 6 13 0>; /* PG13 */ enable-active-high; regulator-boot-on; regulator-always-on; }; reg_vcc_csi: vcc-csi { compatible = "regulator-fixed"; regulator-name = "vcc-csi"; regulator-min-microvolt = <2800000>; regulator-max-microvolt = <2800000>; gpio = <&pio 6 11 0>; /* PG11 */ enable-active-high; regulator-boot-on; regulator-always-on; }; reg_vcc_af_csi: vcc-af-csi { compatible = "regulator-fixed"; regulator-name = "vcc-af-csi"; regulator-min-microvolt = <2800000>; regulator-max-microvolt = <2800000>; gpio = <&pio 0 17 0>; /* PA17 */ enable-active-high; regulator-boot-on; regulator-always-on; }; }; After applying the overlay and rebooting, I can use lsmod to see the camera driver: lsmod | grep "ov5640" ov5640 28672 1 v4l2_fwnode 24576 2 ov5640,sun6i_csi v4l2_async 20480 3 ov5640,v4l2_fwnode,sun6i_csi And I can use the media-ctl command to check the topology: media-ctl --device /dev/media1 --print-topology Media controller API version 5.15.69 Media device information ------------------------ driver sun6i-csi model Allwinner Video Capture Device serial bus info platform:1cb0000.camera hw revision 0x0 driver version 5.15.69 Device topology - entity 1: sun6i-csi (1 pad, 1 link) type Node subtype V4L flags 0 device node name /dev/video1 pad0: Sink <- "ov5640 0-003c":0 [ENABLED] - entity 5: ov5640 0-003c (1 pad, 1 link) type V4L2 subdev subtype Sensor flags 0 device node name /dev/v4l-subdev0 pad0: Source [fmt:UYVY8_2X8/640x480@1/30 field:none colorspace:srgb xfer:srgb ycbcr:601 quantization:full-range] -> "sun6i-csi":0 [ENABLED] However, when I try to use the command to set 1920x1080, it fails: media-ctl --device /dev/media1 --set-v4l2 '"ov5640 1-003c":0[fmt:UYVY8/1920x1080]' Unable to setup formats: Invalid argument (22) I've been staring at the help output for media-ctl but I'm in over my head with this one. I also tried poking around with v4l2-ctl but nothing there seems to be working.
