Subject: ar71xx: Use PHY fixups for Open Mesh MR900
|
|
|
|
The delays of PHY/MAC on the MR900 are done by u-boot and OpenWrt in
|
|
different ways. u-boot only modifies the ETH_CFG of the QCA955x based on
|
|
the link speed. But OpenWrt can only modify the PHY delays based on the
|
|
link speed.
|
|
|
|
This can lead to communication problems when u-boot initializes the ETH_CFG
|
|
for a specific link speed (e.g. 10BASE-T) but then OpenWrt the sets the PHY
|
|
delays to an incompatible value.
|
|
|
|
Instead reset the ETH_CFG delay bits of the QCA955x to a specific value and
|
|
only rely on the AT803x PHY settings.
