In linux kernel since version 4.14.326 (release Date: 2023-09-23)
Many Bay Trail and Cherry Trail devices come with a camera attached
to Intel's Image Signal Processor. Linux currently does not have a
driver for these, so they do not work as a camera. Some of these
camera's have a LED which is controlled through a GPIO.
Some of these devices have a firmware issue where the LED gets turned
on at boot. This driver will turn the LED off at boot and also allows
controlling the LED (repurposing it) through the sysfs LED interface.
Which GPIO is attached to the LED is usually not described in the
ACPI tables, so this driver contains per-system info about the GPIO
inside the driver, this means that this driver only works on systems
the driver knows about.
To compile this driver as a module, choose M here: the module
will be called intel_atomisp2_led.
