783 depends on X86 && ACPI
785 This option enables support for the User1 and User2 LEDs on NI
788 To compile this driver as a module, choose M here: the module
789 will be called leds-nic78bx.
792 tristate "LED support for SPI LED controller with a single byte"
793 depends on LEDS_CLASS
797 This option enables support for LED controller which use a single byte
798 for controlling the brightness. Currently the following controller is
799 supported: Ubiquiti airCube ISP microcontroller based LED controller.
801 config LEDS_TI_LMU_COMMON
802 tristate "LED driver for TI LMU"
803 depends on LEDS_CLASS
806 Say Y to enable the LED driver for TI LMU devices.
807 This supports common features between the TI LM3532, LM3631, LM3632,
808 LM3633, LM3695 and LM3697.
811 tristate "LED driver for LM3697"
812 depends on LEDS_TI_LMU_COMMON
815 Say Y to enable the LM3697 LED driver for TI LMU devices.
816 This supports the LED device LM3697.
819 tristate "LED driver for LM36274"
820 depends on LEDS_TI_LMU_COMMON
821 depends on MFD_TI_LMU
823 Say Y to enable the LM36274 LED driver for TI LMU devices.
824 This supports the LED device LM36274.
