Subject: [PATCH v1] arm64: dts: freescale: imx8mm-verdin: enable hysteresis on slow input pin
Date: Mon, 3 Jun 2024 16:00:45 +0200 [thread overview]
Message-ID: <20240603140103.3845905-1-max.oss.09@gmail.com> (raw)
From: Max Krummenacher <max.krummenacher@toradex.com>
SODIMM 17 can be used as an edge triggered interrupt supplied from an
off board source.
Enable hysteresis on the pinmuxing to increase immunity against noise
on the signal.
Fixes: 60f01b5b5c7d ("arm64: dts: imx8mm-verdin: update iomux configuration")
