The driver provides sysfs interfaces to control and configure the
LP5812 device and its LED channels.

The documetation describes the chip's capabilities, sysfs interface,
and usage examples.

+Kernel driver for lp5812
+========================
+
+* TI/National Semiconductor LP5812 LED Driver
+* Datasheet: https://www.ti.com/product/LP5812#tech-docs
+
+Authors: Jared Zhou <jared-zhou@ti.com>
+
+Description
+===========
+
+The LP5812 is a 4x3 matrix LED driver with support for both manual and
+autonomous animation control. This driver provides sysfs interfaces to
+control and configure the LP5812 device and its LED channels.
+
+Sysfs Interface
+===============
+
+This driver uses the standard multicolor LED class interfaces defined
+in Documentation/ABI/testing/sysfs-class-led-multicolor.rst.
+
+Each LP5812 LED output appears under ``/sys/class/leds/`` with its
+assigned label (for example ``LED_A``).
+
+The following attributes are exposed:
+  - multi_intensity: Per-channel RGB intensity control
+  - brightness: Standard brightness control (0-255)
+
+Autonomous Control Modes
+========================
+
+The driver also supports autonomous control through pattern configuration
+(e.g., direct, tcmscan, or mixscan modes) defined in the device tree.
+When configured, the LP5812 can generate transitions and color effects
+without CPU intervention.
+
+Refer to the device tree binding document for valid mode strings and
+configuration examples.
+
+Example Usage
+=============
+
+To control LED_A::
+    # Set RGB intensity (R=50, G=50, B=50)
+    echo 50 50 50 > /sys/class/leds/LED_A/multi_intensity
+    # Set overall brightness to maximum
+    echo 255 > /sys/class/leds/LED_A/brightness
