+=========================================
+The device for Mediatek MT6370 RGB LED
+=========================================
+
+Description
+-----------
+
+The MT6370 integrates a four-channel RGB LED driver, designed to provide a
+variety of lighting effect for mobile device applications. The RGB LED devices
+includes a smart LED string controller and it can drive 3 channels of LEDs with
+a sink current up to 24mA and a CHG_VIN power good indicator LED with sink
+current up to 6mA. It provides three operation modes for RGB LEDs:
+PWM Dimming mode, breath pattern mode, and constant current mode. The device
+can increase or decrease the brightness of the RGB LED via an I2C interface.
+
+The breath pattern for a channel can be programmed using the "pattern" trigger,
+using the hw_pattern attribute.
+
+/sys/class/leds/<led>/hw_pattern
+--------------------------------
+
+Specify a hardware breath pattern for a MT6370 RGB LED.
+
+The breath pattern is a series of timing pairs, with the hold-time expressed in
+milliseconds. And the brightness is controlled by
+'/sys/class/leds/<led>/brightness'. The pattern doesn't include the brightness
+setting. Hardware pattern only controls the timing for each pattern stage
+depending on the current brightness setting.
+

+  * Tr2:    Second rising time for 31% - 100% load.
+  * Ton:    On time for 100% load.
+  * Tf1:    First falling time for 100% - 31% load.
+  * Tf2:    Second falling time for 30% to 0% load.
+  * Toff:   Off time for 0% load.
+
+  * Tr1/Tr2/Tf1/Tf2/Ton: 125ms to 3125ms, 200ms per step.
+  * Toff: 250ms to 6250ms, 400ms per step.
+
+Pattern example::
+
+       "0 125 0 125 0 125 0 125 0 625 0 1050"
+
+This Will configure Tr1/Tr2/Tf1/Tf2 to 125m, Ton to 625ms, and Toff to 1050ms.

 This is a LED trigger useful for signaling the user of an event where there are
 no clear trap points to put standard led-on and led-off settings.  Using this
 trigger, the application needs only to signal the trigger when an event has
-happened, than the trigger turns the LED on and than keeps it off for a
+happened, then the trigger turns the LED on and then keeps it off for a
 specified amount of time.
 
 This trigger is meant to be usable both for sporadic and dense events.  In the
