Subject: [PATCH v6 1/5] dt-bindings: leds: add TI/National Semiconductor LP5812 LED Driver
Date: Sun, 20 Apr 2025 01:43:29 +0700 [thread overview]
Message-ID: <20250419184333.56617-2-trannamatk@gmail.com> (raw)
In-Reply-To: <20250419184333.56617-1-trannamatk@gmail.com>
The LP5812 is a 4×3 RGB LED driver with an autonomous animation engine
and time-cross-multiplexing (TCM) support for up to 12 LEDs.
It supports both analog (256 levels) and PWM (8-bit) dimming,
including exponential PWM for smooth brightness control.
