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.
