[PATCH net-next 0/8] net: Add support for Synopsys DesignWare XPCS

From: Jose Abreu
Date: Mon Mar 09 2020 - 04:37:27 EST


This adds support for Synopsys DesignWare XPCS in net subsystem and
integrates it into stmmac.

At 1/8, we start by removing the limitation of stmmac selftests that needed
a PHY to pass all the tests.

Then at 2/8 we use some helpers in stmmac so that some code can be
simplified.

At 3/8, we fallback to dev_fwnode() so that PCI based setups wich may
not have CONFIG_OF can still use FW node.

At 4/8, we adapt stmmac to the new PHYLINK changes as suggested by Russell
King.

We proceed by doing changes in PHYLINK in order to support XPCS: At 5/8 we
add some missing speeds that USXGMII supports and at 6/8 we check if
Autoneg is supported after initial parameters are validated.

Support for XPCS is finally introduced at 7/8, along with the usage of it
in stmmac driver at 8/8.
