[PATCH 1/2] dt-bindings: iio: Add TI OPT4048 color sensor bindings

From: Paul Kocialkowski
Date: Sat Nov 30 2024 - 12:42:41 EST


The Texas Instruments OPT4048 is a XYZ tristimulus color sensor.

It requires a VDD power supply and can optionally support an interrupt.

+description: |
+ The device supports both interrupt-driven and interrupt-less operation,
+ depending on whether an interrupt property is present in the device-tree.
+
+properties:
+ compatible:
+ const: ti,opt4048
+
+ reg:
+ maxItems: 1
+
+ interrupts:
+ maxItems: 1
+ description: |
+ The interrupt is detected on a falling edge, with a low level asserted
+ for 1 us. It might be missed because of hardware interrupt debouncing
+ mechanisms due to this short time.
