Subject: [PATCH v4 1/7] iio: light: vcnl4000: Add proximity irq for vcnl4200
Date: Mon, 22 May 2023 16:26:15 +0200 [thread overview]
Message-ID: <20230522142621.1680563-2-astrid.rost@axis.com> (raw)
In-Reply-To: <20230522142621.1680563-1-astrid.rost@axis.com>
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.
