12 includes a smart LED string controller and it can drive 3 channels of LEDs with
14 current up to 6mA. It provides three operation modes for RGB LEDs:
15 PWM Dimming mode, breath pattern mode, and constant current mode. The device
18 The breath pattern for a channel can be programmed using the "pattern" trigger,
21 /sys/class/leds/<led>/hw_pattern
22 --------------------------------
24 Specify a hardware breath pattern for a MT6370 RGB LED.
26 The breath pattern is a series of timing pairs, with the hold-time expressed in
28 '/sys/class/leds/<led>/brightness'. The pattern doesn't include the brightness
29 setting. Hardware pattern only controls the timing for each pattern stage
