[PATCH v3 3/4] pwm: pca9685: Support staggered output ON times

2020-11-24 Thread Clemens Gruber
The PCA9685 supports staggered LED output ON times to minimize current surges and reduce EMI. When this new option is enabled, the ON times of each channel are delayed by channel number x counter range / 16, which avoids asserting all enabled outputs at the same counter value while still
