[PATCH 5.9 082/252] ARM: dts: sun6i: a31-hummingbird: Enable RGMII RX/TX delay on Ethernet PHY

From: Greg Kroah-Hartman
Date: Mon Nov 23 2020 - 07:46:54 EST


From: Chen-Yu Tsai <wens@xxxxxxxx>

[ Upstream commit e76724153f5b4539802cc21b2c6131058668a1c6 ]

The Ethernet PHY on the A31 Hummingbird has the RX and TX delays
enabled on the PHY, using pull-ups on the RXDLY and TXDLY pins.

Fix the phy-mode description to correct reflect this so that the
implementation doesn't reconfigure the delays incorrectly. This
happened with commit bbc4d71d6354 ("net: phy: realtek: fix rtl8211e
rx/tx delay config").

Fixes: c220aec2bb79 ("ARM: dts: sun6i: Add Merrii A31 Hummingbird support")
