net: phy: introduce phydev->port

2021-03-30T12:32:05+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: provide and use genphy_read_status_fixed()

2019-12-19T20:52:34+00:00

There are two drivers and generic code which contain exactly the same
code to read the status of a PHY operating without autonegotiation
enabled. Rather than duplicate this code, provide a helper to read
this information.

net: phy: use phy_resolve_aneg_pause()

2019-12-19T20:52:34+00:00

Several drivers code their own version of this, working from the LPA
register, after setting the ethtool link partner advertisement bitmask.
Use the generic function instead.

net: phy: lxt: Add suspend/resume support to LXT971 and LXT973.

2019-05-23T16:19:21+00:00

All LXT PHYs implement the standard "power down" bit 11 of
BMCR, so this patch adds support using the generic
genphy_{suspend,resume} functions added by
commit 0f0ca340e57b ("phy: power management support").

LXT970 is left aside because all registers get cleared upon
"power down" exit.

net: phy: switch drivers to use dynamic feature detection

2019-04-16T00:19:54+00:00

Recently genphy_read_abilities() has been added that dynamically detects
clause 22 PHY abilities. I *think* this detection should work with all
supported PHY's, at least for the ones with basic features sets, i.e.
PHY_BASIC_FEATURES and PHY_GBIT_FEATURES. So let's remove setting these
features explicitly and rely on phylib feature detection.

I don't have access to most of these PHY's, therefore I'd appreciate
regression testing.

v2:
- make the feature constant a comment so that readers know which
  features are supported by the respective PHY

net: phy: Convert u32 phydev->lp_advertising to linkmode

2018-11-11T18:10:01+00:00

Convert phy drivers to report the link partner advertised modes using
a linkmode bitmap. This allows them to report the higher speeds which
don't fit in a u32.

net: phy: remove flag PHY_HAS_INTERRUPT from driver configs

2018-11-11T17:36:56+00:00

Now that flag PHY_HAS_INTERRUPT has been replaced with a check for
callbacks config_intr and ack_interrupt, we can remove setting this
flag from all driver configs.
Last but not least remove flag PHY_HAS_INTERRUPT completely.
