| |
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.
