From b817a59c2afcfbf1594b9be6c4136d9d7d613eee Mon Sep 17 00:00:00 2001 From: Icenowy Zheng Date: Tue, 9 Jun 2026 00:26:20 +0800 Subject: [PATCH] dt-bindings: display: panel: himax,hx83121a: add optional bl supply When the backlight is managed by the panel controller IC, an external power rail might be powering the backlight. Add an optional `bl-supply` property to describe such power rail, thus allow disabling the backlight.
