This commit adds device tree bindings for veml6030 ambient light sensor. Signed-off-by: Rishi Gupta <gupt21@xxxxxxxxx> --- Changes in v4: * Added enum in reg property * Removed maxItems from reg property Changes in v3: * None Changes in v2: * Corrected grammatical mistake from 'is' to 'are' in description of bindings .../devicetree/bindings/iio/light/veml6030.yaml | 62 ++++++++++++++++++++++ 1 file changed, 62 insertions(+) create mode 100644 Documentation/devicetree/bindings/iio/light/veml6030.yaml diff --git a/Documentation/devicetree/bindings/iio/light/veml6030.yaml b/Documentation/devicetree/bindings/iio/light/veml6030.yaml new file mode 100644 index 0000000..0ff9b11 --- /dev/null +++ b/Documentation/devicetree/bindings/iio/light/veml6030.yaml @@ -0,0 +1,62 @@ +# SPDX-License-Identifier: GPL-2.0+ +%YAML 1.2 +--- +$id: http://devicetree.org/schemas/iio/light/veml6030.yaml# +$schema: http://devicetree.org/meta-schemas/core.yaml# + +title: VEML6030 Ambient Light Sensor (ALS) + +maintainers: + - Rishi Gupta <gupt21@xxxxxxxxx> + +description: | + Bindings for the ambient light sensor veml6030 from Vishay + Semiconductors over an i2c interface. + + Irrespective of whether interrupt is used or not, application + can get the ALS and White channel reading from IIO raw interface. + + If the interrupts are used, application will receive an IIO event + whenever configured threshold is crossed. + + Specifications about the sensor can be found at: + https://www.vishay.com/docs/84366/veml6030.pdf + +properties: + compatible: + enum: + - vishay,veml6030 + + reg: + description: + I2C address of the device. + enum: + - 0x10 # ADDR pin pulled down + - 0x48 # ADDR pin pulled up + + interrupts: + description: + interrupt mapping for IRQ.
