Reviewed-by: Krzysztof Kozlowski Signed-off-by: Quentin Schulz --- v4: - added Reviewed-by, v3: - removed clock-names, - removed clock-frequency, - added all-of of video-interface-devices schema, - added clock frequency range in description, - rephrased definition of supplies, - fixed name of reset gpio, - used schema ref for port and port->endpoint, - removed mentions to driver, - added HW data transfer speed limitation in comment for link-frequencies, - changed root additionalProperties to unevaluatedProperties to not have to list all properties from video-interface-devices schema, such as orientation or rotation, - added maxItems to reset-gpios, - updated example to use assigned-clocks and assigned-clock-rates instead of clock-frequency and clock-names, v2: - fixed incorrect id, - fixed device tree example by adding missing dt-bindings headers, - fixed device tree example by using vcc_1v2 for dvdd supply, as requested in datasheet, .../bindings/media/i2c/ovti,ov5675.yaml | 123 ++++++++++++++++++ MAINTAINERS | 1 + 2 files changed, 124 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/ovti,ov5675.yaml diff --git a/Documentation/devicetree/bindings/media/i2c/ovti,ov5675.yaml b/Documentation/devicetree/bindings/media/i2c/ovti,ov5675.yaml new file mode 100644 index 0000000000000..f0a48707bed77 --- /dev/null +++ b/Documentation/devicetree/bindings/media/i2c/ovti,ov5675.yaml @@ -0,0 +1,123 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +# Copyright (c) 2022 Theobroma Systems Design und Consulting GmbH +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/media/i2c/ovti,ov5675.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: Omnivision OV5675 CMOS Sensor + +maintainers: + - Quentin Schulz + +allOf: + - $ref: /schemas/media/video-interface-devices.yaml# + +description: | + The Omnivision OV5675 is a high performance, 1/5-inch, 5 megapixel, CMOS + image sensor that delivers 2592x1944 at 30fps.
