Subject: [PATCH v3 5/7] ARM i.MX6q: remove Atheros AR8035 SmartEEE fixup
Date:   Tue, 11 May 2021 06:37:33 +0200
Message-Id: <20210511043735.30557-6-o.rempel@pengutronix.de>

This fixup removes the Lpi_en bit.

If this patch breaks functionality of your board, use following device
tree properties: qca,smarteee-tw-us-1g and qca,smarteee-tw-us-100m.

For example:

	ethernet-phy@X {
		reg = <0xX>;
		qca,smarteee-tw-us-1g = <24>;
		....
	};
