0014 Many Bay Trail and Cherry Trail devices come with a camera attached
0015 to Intel's Image Signal Processor. Linux currently does not have a
0016 driver for these, so they do not work as a camera. Some of these
0017 camera's have a LED which is controlled through a GPIO.
0018
0019 Some of these devices have a firmware issue where the LED gets turned
0020 on at boot. This driver will turn the LED off at boot and also allows
0021 controlling the LED (repurposing it) through the sysfs LED interface.
0022
0023 Which GPIO is attached to the LED is usually not described in the
0024 ACPI tables, so this driver contains per-system info about the GPIO
0025 inside the driver, this means that this driver only works on systems
0026 the driver knows about.

0028 To compile this driver as a module, choose M here: the module
0029 will be called intel_atomisp2_led.

0037 Power-management driver for Intel's Image Signal Processor found on
0038 Bay Trail and Cherry Trail devices. This dummy driver's sole purpose
0039 is to turn the ISP off (put it in D3) to save power and to allow
0040 entering of S0ix modes.

0042 To compile this driver as a module, choose M here: the module
0043 will be called intel_atomisp2_pm.
