[PATCH 5.13 015/175] arm64: dts: ls1028: sl28: fix networking for variant 2

From: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
Date: 2021-08-10 17:53:28
Also in: lkml
Subsystem: arm/freescale imx / mxc / layerscape arm architecture, the rest · Maintainers: Frank Li, Sascha Hauer, Linus Torvalds

From: Michael Walle <redacted>

[ Upstream commit 29f6a20c21b5bdc7eb623a712bbf7b99612ee746 ]

The PHY configuration for the variant 2 is still missing the flag for
in-band signalling between PHY and MAC. Both sides - MAC and PHY - have
to match the setting. For now, Linux only supports setting the MAC side
and thus it has to match the setting the bootloader is configuring.
Enable in-band signalling to make ethernet work.
