Subject: [PATCH 2/3] arm64: dts: imx95-15x15-evk: fix the overshoot issue of NETC
Date: Wed, 28 May 2025 16:34:32 +0800 [thread overview]
Message-ID: <20250528083433.3861625-3-wei.fang@nxp.com> (raw)
In-Reply-To: <20250528083433.3861625-1-wei.fang@nxp.com>
The overshoot of MDIO, MDC, ENET1_TDx and ENET2_TDx is too high, so
reduce the drive strength of these pins.
Fixes: e3e8b199aff8 ("arm64: dts: imx95: Add imx95-15x15-evk support")
Signed-off-by: Wei Fang <wei.fang@nxp.com>
