Subject: [PATCH 1/2] dt-bindings: regulators: Add bindings for Maxim MAX20086-MAX20089
Date: Sun, 2 Jan 2022 23:11:23 +0200 [thread overview]
Message-ID: <20220102211124.18435-2-laurent.pinchart+renesas@ideasonboard.com> (raw)
In-Reply-To: <20220102211124.18435-1-laurent.pinchart+renesas@ideasonboard.com>
From: Laurent Pinchart <laurent.pinchart@ideasonboard.com>
The MAX20086-MAX20089 are dual/quad power protectors for cameras. Add
corresponding DT bindings.

+ The MAX20086-MAX20089 are dual/quad camera power protectors, designed to
+ deliver power over coax for radar and camera modules. They support
+ software-configurable output switching and monitoring. The output voltage and
+ current limit are fixed by the hardware design.
