Subject: [PATCH v1 2/7] ARM i.MX6q: remove TX clock delay of ar8031_phy_fixup()
Date: Wed,  3 Feb 2021 10:18:52 +0100	[thread overview]
Message-ID: <20210203091857.16936-3-o.rempel@pengutronix.de> (raw)
In-Reply-To: <20210203091857.16936-1-o.rempel@pengutronix.de>

In case the at803x PHY driver is activated in the kernel, the TX clock
fixup is overwritten by at803x_config_init(), in this case no additional
device tree changes are needed.

If this patch breaks your system, please enable AT803X_PHY driver and
add the following device tree property to the PHY node:

    phy-mode = "rgmii-txid";
