[devel] [PATCH 29/35] arm64: device tree: Baikal-M: fixed PHY binding description

[asheplyakov на yandex.ru]

From: Alexey Sheplyakov <asheplyakov на altlinux.org>

According to the documentation [1] Ethernet PHY binding `compatible`
string should be one of ethernet-phy-ieee802.3-{c22,c45}, and
(optionally) PHY ID (if the PHY reports incorrect ID or none at all).

Since v5.14 the kernel rejects PHY description if the `compatible`
contains wrong entries. As a result Ethernet driver is unable to
attach the PHY (and Ethernet can't transmit/receive any packets).

This patch removes extraneous entries (`micrel,ksz9031`) from PHY
binding nodes to avoid the problem.
