net: phy: extract pause mode

2019-10-05T01:11:08+00:00

Extract the update of phylib's software pause mode state from
genphy_read_status(), so that we can re-use this functionality with
PHYs that have alternative ways to read the negotiation results.

net: phy: extract link partner advertisement reading

2019-10-05T01:11:08+00:00

Move reading the link partner advertisement out of genphy_read_status()
into its own separate function.  This will allow re-use of this code by
PHY drivers that are able to read the resolved status from the PHY.

Add genphy_c45_config_aneg() function to phy-c45.c

2019-08-28T03:21:15+00:00

Commit 34786005eca3 ("net: phy: prevent PHYs w/o Clause 22 regs from calling
genphy_config_aneg") introduced a check that aborts phy_config_aneg()
if the phy is a C45 phy.
This causes phy_state_machine() to call phy_error() so that the phy
ends up in PHY_HALTED state.

Instead of returning -EOPNOTSUPP, call genphy_c45_config_aneg()
(analogous to the C22 case) so that the state machine can run
correctly.

genphy_c45_config_aneg() closely resembles mv3310_config_aneg()
in drivers/net/phy/marvell10g.c, excluding vendor specific
configurations for 1000BaseT.

net: phy: let phy_speed_down/up support speeds >1Gbps

2019-08-14T00:14:06+00:00

So far phy_speed_down/up can be used up to 1Gbps only. Remove this
restriction by using new helper __phy_speed_down. New member adv_old
in struct phy_device is used by phy_speed_up to restore the advertised
modes before calling phy_speed_down. Don't simply advertise what is
supported because a user may have intentionally removed modes from
advertisement.

net: phy: add phy_speed_down_core and phy_resolve_min_speed

2019-08-14T00:14:06+00:00

phy_speed_down_core provides most of the functionality for
phy_speed_down. It makes use of new helper phy_resolve_min_speed that is
based on the sorting of the settings[] array. In certain cases it may be
helpful to be able to exclude legacy half duplex modes, therefore
prepare phy_resolve_min_speed() for it.

v2:
- rename __phy_speed_down to phy_speed_down_core

net: phy: prepare phylib to deal with PHY's extending Clause 22

2019-08-12T04:24:32+00:00

The integrated PHY in 2.5Gbps chip RTL8125 is the first (known to me)
PHY that uses standard Clause 22 for all modes up to 1Gbps and adds
2.5Gbps control using vendor-specific registers. To use phylib for
the standard part little extensions are needed:
- Move most of genphy_config_aneg to a new function
  __genphy_config_aneg that takes a parameter whether restarting
  auto-negotiation is needed (depending on whether content of
  vendor-specific advertisement register changed).
- Don't clear phydev->lp_advertising in genphy_read_status so that
  we can set non-C22 mode flags before.

Basically both changes mimic the behavior of the equivalent Clause 45
functions.

net: phy: make exported variables non-static

2019-07-12T22:26:29+00:00

The variables phy_basic_ports_array, phy_fibre_port_array and
phy_all_ports_features_array are declared static and marked
EXPORT_SYMBOL_GPL(), which is at best an odd combination.
Because the variables were decided to be a part of API, this commit
removes the static attributes and adds the declarations to the header.
