Subject: [PATCH 630/634] arm64: device tree: Baikal-M: fixed PHY binding
|
||
|
|
description
|
||
|
|
|
||
|
|
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.
