net: phy: introduce phydev->port

2021-03-30T12:30:27+00:00

[ Upstream commit 4217a64e18a1647a0dbc68cb3169a5a06f054ec8 ] At the moment, PORT_MII is reported in the ethtool ops. This is odd because it is an interface between the MAC and the PHY and no external port. Some network card drivers will overwrite the port to twisted pair or fiber, though. Even worse, the MDI/MDIX setting is only used by ethtool if the port is twisted pair. Set the port to PORT_TP by default because most PHY drivers are copper ones. If there is fibre support and it is enabled, the PHY driver will set it to PORT_FIBRE. This will change reporting PORT_MII to either PORT_TP or PORT_FIBRE; except for the genphy fallback driver.

net: phy: remove the .did_interrupt() and .ack_interrupt() callback

2020-11-25T19:18:38+00:00

Now that all the PHY drivers have been migrated to directly implement the generic .handle_interrupt() callback for a seamless support of shared IRQs and all the .config_inter() implementations clear any pending interrupts, we can safely remove the two callbacks. With this patch, phylib has a proper support for shared IRQs (and not just for multi-PHY devices. A PHY driver must implement both the .handle_interrupt() and .config_intr() callbacks for the IRQs to be actually used. Signed-off-by: Ioana Ciornei Signed-off-by: Jakub Kicinski

net: phy: add genphy_handle_interrupt_no_ack()

2020-11-06T00:32:39+00:00

It seems there are cases where the interrupts are handled by another entity (ie an IRQ controller embedded inside the PHY) and do not need any other interraction from phylib. For this kind of PHYs, like the RTL8366RB, add the genphy_handle_interrupt_no_ack() function which just triggers the link state machine. Signed-off-by: Ioana Ciornei Signed-off-by: Jakub Kicinski

net: phy: export phy_error and phy_trigger_machine

2020-11-06T00:31:59+00:00

These functions are currently used by phy_interrupt() to either signal an error condition or to trigger the link state machine. In an attempt to actually support shared PHY IRQs, export these two functions so that the actual PHY drivers can use them.
