tristate "Intel AtomISP v2 camera LED driver"
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.

help
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.
