Backport workaround for QCA8327 PHY resume, which does not properly support genphy_suspend/resume. Also add DAC amplitude fix for the QCA8327 PHY, set port to preferred master and add proper names to debug regs.

Subject: [PATCH] net: phy: at803x: fix feature detection
|
|
|
|
AR8031/AR8033 have different status registers for copper
|
|
and fiber operation. However, the extended status register
|
|
is the same for both operation modes.
|
|
|
|
As a result of that, ESTATUS_1000_XFULL is set to 1 even when
|
|
operating in copper TP mode.
|
|
|
|
Remove this mode from the supported link modes, as this driver
|
|
currently only supports copper operation.
