Until upstream commit 6d4cd041f0af("net: phy: at803x: disable delay
|
|
only for RGMII mode"), delays were not disabled on driver probe
|
|
for the Atheros AR803x PHYs, although the RX delay is enabled on
|
|
soft and hard reset.
|
|
|
|
In addition, the TX delay setting is retained on soft-reset.
|
|
|
|
This patch disables both delays on config init to align the behavior
|
|
with kernel 5.1 and higher. It can be safely dropped with kernel 5.1.
