net: phy: ensure that phy IDs are correctly typed

2019-12-31T15:41:26+00:00

[ Upstream commit 7d49a32a66d2215c5b3bf9bc67c9036ea9904111 ] PHY IDs are 32-bit unsigned quantities. Ensure that they are always treated as such, and not passed around as "int"s.

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. Tested-by: tinywrkb Reviewed-by: Andrew Lunn Signed-off-by: Russell King Signed-off-by: David S. Miller

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. Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: Jakub Kicinski

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 Signed-off-by: Heiner Kallweit Reviewed-by: Andrew Lunn Signed-off-by: Jakub Kicinski

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. Signed-off-by: Heiner Kallweit Signed-off-by: David S. Miller
