ROHM BD2802GU is a RGB LED controller attached to i2c bus and specifically engineered for decoration purposes. This RGB controller incorporates lighting patterns and illuminates. This driver is designed to minimize power consumption, so when there is no emitting LED, it enters to reset state. And because the BD2802GU has lots of features that can't be covered by the current LED framework, it provides Advanced Configuration Function(ADF) mode, so that user applications can set registers of BD2802GU directly. Here are basic usage examples : ; to turn on LED (not blink) $ echo 1 > /sys/class/leds/led1_R/brightness ; to blink LED $ echo timer > /sys/class/leds/led1_R/trigger $ echo 1 > /sys/class/leds/led1_R/delay_on $ echo 1 > /sys/class/leds/led1_R/delay_off ; to turn off LED $ echo 0 > /sys/class/leds/led1_R/brightness [akpm@linux-foundation.org: coding-style fixes] Signed-off-by: Kim Kyuwon <chammoru@gmail.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Richard Purdie <rpurdie@linux.intel.com>

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.
