Subject: [PATCH v1 0/2] arm64: dts: freescale: imx8mp-toradex-smarc: remove gpio-hog on lvds_dsi_sel
Date: Tue, 8 Jul 2025 15:51:40 +0200 [thread overview]
Message-ID: <20250708135300.2855155-1-max.oss.09@gmail.com> (raw)
From: Max Krummenacher <max.krummenacher@toradex.com>
The LVDS_DSI_SEL does not leave the SoM, so do its pinmuxing on the SoM dtsi and don't
leave that to a carrier board dts file.
Using a pull down on the LVDS_DSI_SEL signal is enough to have the signal not floating
and have the SoM in a defined state.
Thus remove the gpio-hog used on the line and leave this to carrier board dts files or
overlays to use the signal as needed.
