From 854965b7db63636e753130633f7762c26adb7f3d Mon Sep 17 00:00:00 2001 From: Astrid Rost Date: Tue, 13 Jun 2023 15:50:17 +0200 Subject: iio: light: vcnl4000: Add proximity irq for vcnl4200 Add proximity interrupt support for vcnl4200 (similar to vcnl4040). Add support to configure proximity sensor interrupts and threshold limits. If an interrupt is detected an event will be pushed to the event interface.
