Subject: [PATCH] net: bgmac: connect to PHY even if it is BGMAC_PHY_NOREGS

Recent bgmac change was meant to just fix a race between "Generic PHY"
|
|
and "bcm53xx" drivers after -EPROBE_DEFER. It modified bgmac to use
|
|
phy_connect() only if there is a real PHY device connected.
|
|
|
|
That change broke bgmac on bcm47xx. bcma_phy_connect() now registers a
|
|
fixed PHY with the bgmac_phy_connect_direct(). That fails as another
|
|
fixed PHY (also using address 0) is already registered - by bcm47xx arch
|
|
code bcm47xx_register_bus_complete().
|
|
|
|
This change brings origial behaviour. It connects Ethernet interface
|
|
with pseudo-PHY (switch device) and adjusts Ethernet interface link to
|
|
match connected switch.
|
|
|
|
This fixes:
|
|
[ 2.548098] bgmac_bcma bcma0:1: Failed to register fixed PHY device
|
|
[ 2.554584] bgmac_bcma bcma0:1: Cannot connect to phy
|
|
|
|
Fixes: b5375509184d ("net: bgmac: improve handling PHY")
