		Description:
		Maximum brightness for <backlight>.
		Users: HAL

		What: /sys/class/backlight/<backlight>/type
		Date: September 2010
		KernelVersion: 2.6.37

		Description:
		The type of interface controlled by <backlight>.
		"firmware": The driver uses a standard firmware interface
		"platform": The driver uses a platform-specific interface
		"raw": The driver controls hardware registers directly

		In the general case, when multiple backlight
		interfaces are available for a single device, firmware
		control should be preferred to platform control should
		be preferred to raw control. Using a firmware
		interface reduces the probability of confusion with
		the hardware and the OS independently updating the
		backlight state. Platform interfaces are mostly a
		holdover from pre-standardisation of firmware
		interfaces.

		Description:

		Interface is used to configure selected dual mode PCIe controller
		as device and then program its various registers to configure it
		as a particular device type.
		This interfaces can be used to show spear's PCIe device capability.

		Nodes are only visible when configfs is mounted. To mount configfs
		in /config directory use:
		# mount -t configfs none /config/

		For nth PCIe Device Controller
		/config/pcie-gadget.n/

		int_type ...used to configure and read type of supported
		interrupt
		no_of_msi ... used to configure number of MSI vector needed and
		to read no of MSI granted.
		inta ... write 1 to assert INTA and 0 to de-assert.
		send_msi ... write MSI vector to be sent.
		vendor_id ... used to write and read vendor id (hex)
		device_id ... used to write and read device id (hex)
		bar0_size ... used to write and read bar0_size
		bar0_address ... used to write and read bar0 mapped area in hex.
		bar0_rw_offset ... used to write and read offset of bar0 where
		bar0_data will be written or read.
		bar0_data ... used to write and read data at bar0_rw_offset.
