The Linux kernel configuration item CONFIG_INTEL_ATOMISP2_LED
has multiple definitions:
drivers/platform/x86/intel/atomisp2/Kconfig
The configuration item CONFIG_INTEL_ATOMISP2_LED:
CONFIG_GPIOLIB && CONFIG_LEDS_GPIO
intel_atomisp2_led
, intel_atomisp2_led
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.
