Subject: [PATCH 1/2] dt-bindings: leds: irled: pwm-ir-tx: add power supply support
Date: Mon, 02 Nov 2026 17:22:56 +0200 [thread overview]
Message-ID: <20261102-6768-irled-v1-1-c7064f3afed1@protonmail.com> (raw)
In-Reply-To: <20261102-6768-irled-v1-0-c7064f3afed1@protonmail.com>
From: Roman Vivchar <rva333@protonmail.com>
On some boards, the IR LED is connected to a switchable power rail, such
as an eMMC supply. If this regulator is disabled, IR transmission fails.
Add an optional power-supply property to document this regulator.
