14 	  Many Bay Trail and Cherry Trail devices come with a camera attached
15 	  to Intel's Image Signal Processor. Linux currently does not have a
16 	  driver for these, so they do not work as a camera. Some of these
17 	  camera's have a LED which is controlled through a GPIO.
18 
19 	  Some of these devices have a firmware issue where the LED gets turned
20 	  on at boot. This driver will turn the LED off at boot and also allows
21 	  controlling the LED (repurposing it) through the sysfs LED interface.
22 
23 	  Which GPIO is attached to the LED is usually not described in the
24 	  ACPI tables, so this driver contains per-system info about the GPIO
25 	  inside the driver, this means that this driver only works on systems
26 	  the driver knows about.
27 
28 	  To compile this driver as a module, choose M here: the module
29 	  will be called intel_atomisp2_led.

37 	  Power-management driver for Intel's Image Signal Processor found on
38 	  Bay Trail and Cherry Trail devices. This dummy driver's sole purpose
39 	  is to turn the ISP off (put it in D3) to save power and to allow
40 	  entering of S0ix modes.
