- 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.
