Subject: [PATCH v1] arm64: dts: ti: k3-am62p-verdin: Enable pull-ups on I2C_3_HDMI
Date: Thu, 29 May 2025 12:25:54 +0200 [thread overview]
Message-ID: <20250529102601.452859-1-ghidoliemanuele@gmail.com> (raw)
From: Emanuele Ghidoli <emanuele.ghidoli@toradex.com>
Enable internal bias pull-ups on the SoC-side I2C_3_HDMI that do not have
external pull resistors populated on the SoM. This ensures proper
default line levels.
Fixes: 87f95ea316ac ("arm64: dts: ti: Add Toradex Verdin AM62P")
