|
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.
