Subject: [PATCH v2 3/3] ARM: dts: imx6: phycore-som: Add phy-reset-duration
Date: Thu, 1 Oct 2026 09:09:47 +0200 [thread overview]
Message-ID: <20261001070947.1815279-4-primoz.fiser@norik.com> (raw)
In-Reply-To: <20261001070947.1815279-1-primoz.fiser@norik.com>
Without an explicit phy-reset-duration, fec_reset_phy() defaults the
phy-reset-gpios assertion to 1 ms. Extend it to 10 ms for a more robust
PHY reset pulse as otherwise Ethernet PHY probing occasionally fails.
Signed-off-by: Primoz Fiser <primoz.fiser@norik.com>

Changes in v2:
- drop patch #3 from v1
- convert patch #4 from v1 to phy-reset-duration instead
