It is generally only usefull as a platform driver config LEDS_GPIO tristate "LED Support for GPIO connected LEDs" depends on LEDS_CLASS && GENERIC_GPIO help This option enables support for the LEDs connected to GPIO outputs. To be useful the particular board must have LEDs and they must be connected to the GPIO lines. config LEDS_HP_DISK tristate "LED Support for disk protection LED on HP notebooks" depends on LEDS_CLASS && ACPI help This option enable support for disk protection LED, found on newer HP notebooks. config LEDS_CLEVO_MAIL tristate "Mail LED on Clevo notebook (EXPERIMENTAL)" depends on LEDS_CLASS && X86 && SERIO_I8042 && DMI && EXPERIMENTAL help This driver makes the mail LED accessible from userspace programs through the leds subsystem. This LED have three known mode: off, blink at 0.5Hz and blink at 1Hz. The driver supports two kinds of interface: using ledtrig-timer or through /sys/class/leds/clevo::mail/brightness. As this LED cannot change it's brightness it blinks instead. The brightness value 0 means off, 1..127 means blink at 0.5Hz and 128..255 means blink at 1Hz. This module can drive the mail LED for the following notebooks: Clevo D400P Clevo D410J Clevo D410V Clevo D400V/D470V (not tested, but might work) Clevo M540N Clevo M5x0N (not tested, but might work) Positivo Mobile (Clevo M5x0V) If your model is not listed here you can try the "nodetect" module paramter. To compile this driver as a module, choose M here: the module will be called leds-clevo-mail. config LEDS_PCA955X tristate "LED Support for PCA955x I2C chips" depends on LEDS_CLASS && I2C help This option enables support for LEDs connected to PCA955x LED driver chips accessed via the I2C bus.
