Why This File Exists

Repeatable hardware-adapter layer. Deep compatibility for every driver is out of scope; this atlas records patterns, probe lifecycles, bus glue, IRQ/DMA usage, and links back to core abstractions.

	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.

config INTEL_ATOMISP2_PM
	tristate "Intel AtomISP v2 dummy / power-management driver"
	depends on PCI && IOSF_MBI && PM
	depends on !INTEL_ATOMISP
	select INTEL_ATOMISP2_PDX86
	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.
