Add device tree binding for the onsemi AR0144 CMOS camera sensor. The binding supports both the monochrome and color sensor versions. Signed-off-by: Laurent Pinchart <laurent.pinchart@xxxxxxxxxxxxxxxx> --- Changes since v1: - Drop clock-names - Rename vdd_io-supply to vddio supply - Drop unnecessary | --- .../bindings/media/i2c/onnn,ar0144.yaml | 162 ++++++++++++++++++ MAINTAINERS | 6 + 2 files changed, 168 insertions(+) create mode 100644 Documentation/devicetree/bindings/media/i2c/onnn,ar0144.yaml diff --git a/Documentation/devicetree/bindings/media/i2c/onnn,ar0144.yaml b/Documentation/devicetree/bindings/media/i2c/onnn,ar0144.yaml new file mode 100644 index 000000000000..50e0908b6473 --- /dev/null +++ b/Documentation/devicetree/bindings/media/i2c/onnn,ar0144.yaml @@ -0,0 +1,162 @@ +# SPDX-License-Identifier: (GPL-2.0-only OR BSD-2-Clause) +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/media/i2c/onnn,ar0144.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: ON Semiconductor AR0144 MIPI CSI-2 sensor + +maintainers: + - Krzysztof Hałasa <khalasa@xxxxxxx> + +description: | + The AR0144 is a 1/4" 1MP raw CMOS image sensor with MIPI CSI-2 and parallel + outputs, and an I2C-compatible control interface. + + The sensor comes in a regular CMOS version (AR0144CS) and an automotive + version (AR0144AT).
