Subject: [PATCH v8 1/5] dt-bindings: auxdisplay: add TI LP5812 4×3 Matrix RGB LED Driver
Date: Sun, 27 Apr 2025 15:24:43 +0700	[thread overview]
Message-ID: <20250427082447.138359-2-trannamatk@gmail.com> (raw)
In-Reply-To: <20250427082447.138359-1-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.
