Linux currently does not have a 16 driver for these, so they do not work as a camera. Some of these 17 camera's have a LED which is controlled through a GPIO. 18 19 Some of these devices have a firmware issue where the LED gets turned 20 on at boot. This driver will turn the LED off at boot and also allows 21 controlling the LED (repurposing it) through the sysfs LED interface. 22 23 Which GPIO is attached to the LED is usually not described in the 24 ACPI tables, so this driver contains per-system info about the GPIO 25 inside the driver, this means that this driver only works on systems 26 the driver knows about. 27 28 To compile this driver as a module, choose M here: the module 29 will be called intel_atomisp2_led. 30 31config INTEL_ATOMISP2_PM 32 tristate "Intel AtomISP v2 dummy / power-management driver" 33 depends on PCI && IOSF_MBI && PM 34 depends on !INTEL_ATOMISP 35 select INTEL_ATOMISP2_PDX86 36 help 37 Power-management driver for Intel's Image Signal Processor found on 38 Bay Trail and Cherry Trail devices.
