+ depends on GPIOLIB && LEDS_GPIO
+ select INTEL_ATOMISP2_PDX86
+ help
+ 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.

+ Power-management driver for Intel's Image Signal Processor found on
+ Bay Trail and Cherry Trail devices. This dummy driver's sole purpose
+ is to turn the ISP off (put it in D3) to save power and to allow
+ entering of S0ix modes.
+
+ To compile this driver as a module, choose M here: the module
+ will be called intel_atomisp2_pm.
