Ricardo de Almeida Gonzaga 781375f1d1 x86: Add PCA9685 support ... This patch adds pwm-pca9685.c and pwm-pca9685.h files, which support access to I2C-based PCA9685 PWM controller configuration register through a function interface. The PCA9685 is an I2C-bus controlled 16-channel LED controller optimized for Red/Green/Blue/Amber (RGBA) color backlighting applications. Each LED output has its own 12-bit resolution (4096 steps) fixed frequency individual PWM controller that operates at a programmable frequency from a typical of 24 Hz to 1526 Hz with a duty cycle that is adjustable from 0 % to 100 % to allow the LED to be set to a specific brightness value. More about PCA9685 can be found in its datasheet[1]. This driver is needed in order to configure Galileo pinmux. [1] - http://www.nxp.com/documents/data_sheet/PCA9685.pdf		2015-12-21 08:06:14 -02:00
