Subject: [PATCH 0/2] Support for Texas Instruments OPT4001 Ambient Light Sensor
Date: Tue, 4 Apr 2023 11:07:41 +0200 [thread overview]
Message-ID: <20230323-add-opt4001-driver-v1-0-1451dcc1bc8a@axis.com> (raw)
This series adds support for Texas Instruments OPT4001 Ambient light sensor.
The light sensor has a i2c interface and supports continuous, oneshot and
interruptdriven measurements and has configurable conversion time and range.
This driver uses the sensors continuous mode so it always has a updated light
value available. The conversion time which is
(integration time + time to set registers) which is used to configure
integration time through sysfs. The chip also has a configurable light
range which this driver sets to Auto where the chip chooses range itself
depending on previously read values.
Since the OPT4001 has different constants used to calculate lux values
depeding on packaging of the chip but uses the same device id, two compatible
string are used depending on the packaging, these are "ti,opt4001-picostar"
and "ti,opt4001-sot-5x3".
