From 3bd71a34baf620b2a85b5b63255a07a4ab194da0 Mon Sep 17 00:00:00 2001 From: Mathis Foerst Date: Thu, 22 May 2025 16:35:05 +0200 Subject: [PATCH] media: dt-bindings: mt9m114: Add slew-rate DT-binding The MT9M114 supports the different slew rates (0 to 7) on the output pads. At the moment, this is hardcoded to 7 (the fastest rate). The user might want to change this values due to EMC requirements. Add the 'slew-rate' property to the MT9M114 DT-bindings for selecting the desired slew rate.
