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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
