Subject: [PATCH 1/3] arm64: dts: imx95-19x19-evk: fix the overshoot issue of NETC
Date: Wed, 28 May 2025 16:34:31 +0800 [thread overview]
Message-ID: <20250528083433.3861625-2-wei.fang@nxp.com> (raw)
In-Reply-To: <20250528083433.3861625-1-wei.fang@nxp.com>
The overshoot of MDIO, MDC and ENET1_TDx is too high, so reduce the drive
strength these pins.
Fixes: 025cf78938c2 ("arm64: dts: imx95-19x19-evk: add ENETC 0 support")
Signed-off-by: Wei Fang <wei.fang@nxp.com>
