leds: Add LED1202 I2C driver
The output current can be adjusted separately for each channel by 8-bit
analog (current sink input) and 12-bit digital (PWM) dimming control. The
LED1202 implements 12 low-side current generators with independent dimming
control.
Internal volatile memory allows the user to store up to 8 different patterns,
each pattern is a particular output configuration in terms of PWM
duty-cycle (on 4096 steps). Analog dimming (on 256 steps) is per channel but
common to all patterns. Each device tree LED node will have a corresponding
entry in /sys/class/leds with the label name. The brightness property
corresponds to the per channel analog dimming, while the patterns[1-8] to the
PWM dimming control.
