Ihis chip supports high frame rate speeds up to 30fps 17 @ 1600x1200 (UXGA) resolution transferred over a 1-lane MIPI interface. The 18 sensor output is available via CSI-2 serial data output. 19 20allOf: 21 - $ref: /schemas/media/video-interface-devices.yaml# 22 23properties: 24 compatible: 25 const: ovti,ov02a10 26 27 reg: 28 maxItems: 1 29 30 clocks: 31 maxItems: 1 32 33 clock-names: 34 description: 35 External clock for the sensor. 36 items: 37 - const: eclk 38 39 clock-frequency: 40 description: 41 Frequency of the eclk clock in Hz. 42 43 dovdd-supply: 44 description: 45 Definition of the regulator used as Digital I/O voltage supply. 46 47 avdd-supply: 48 description: 49 Definition of the regulator used as Analog voltage supply. 50 51 dvdd-supply: 52 description: 53 Definition of the regulator used as Digital core voltage supply. 54 55 powerdown-gpios: 56 description: 57 Must be the device tree identifier of the GPIO connected to the 58 PD_PAD pin.
