Subject: [PATCH v2 1/2] dt-bindings: display/bridge: lt9211: Add drive-strength-microamp property
Date: Wed, 13 May 2026 15:31:26 +0200 [thread overview]
Message-ID: <20260513133127.376458-2-bstruempfel@data-modul.com> (raw)
In-Reply-To: <20260513133127.376458-1-bstruempfel@data-modul.com>
Add the 'drive-strength-microamp' property to allow board DTs to
configure the LT9211 LVDS TX output driver current. Sixteen discrete
levels are supported, ranging from 12 uA to 36 uA. Defaults to 25 uA.
