net: phy: broadcom: re-add check for PHY_BRCM_DIS_TXCRXC_NOENRGY on the BCM54811 PHY

2021-07-25T09:45:49+00:00

Restore PHY_ID_BCM54811 accidently removed by commit 5d4358ede8eb. Fixes: 5d4358ede8eb ("net: phy: broadcom: Allow BCM54210E to configure APD") Signed-off-by: Kevin Lo Acked-by: Florian Fainelli Signed-off-by: David S. Miller

net: phy: broadcom: Add statistics for all Gigabit PHYs

2021-04-01T22:59:26+00:00

All Gigabit PHYs use the same register layout as far as fetching statistics goes. Fast Ethernet PHYs do not all support statistics, and the BCM54616S would require some switching between the coper and fiber modes to fetch the appropriate statistics which is not supported yet.

net: phy: broadcom: Fix RGMII delays for BCM50160 and BCM50610M

2021-03-13T00:54:57+00:00

The PHY driver entry for BCM50160 and BCM50610M calls bcm54xx_config_init() but does not call bcm54xx_config_clock_delay() in order to configuration appropriate clock delays on the PHY, fix that.

net: phy: broadcom: Add power down exit reset state delay

2021-03-12T02:25:19+00:00

Per the datasheet, when we clear the power down bit, the PHY remains in an internal reset state for 40us and then resume normal operation. Account for that delay to avoid any issues in the future if genphy_resume() changes.

net: phy: broadcom: Do not modify LED configuration for SFP module PHYs

2021-02-16T23:23:23+00:00

bcm54xx_config_init was modifying the PHY LED configuration to enable link and activity indications. However, some SFP modules (such as Bel-Fuse SFP-1GBT-06) have no LEDs but use the LED outputs to control the SFP LOS signal, and modifying the LED settings will cause the LOS output to malfunction. Skip this configuration for PHYs which are bound to an SFP bus. Signed-off-by: Robert Hancock Signed-off-by: David S. Miller

net: phy: broadcom: Set proper 1000BaseX/SGMII interface mode for BCM54616S

2021-02-16T23:23:23+00:00

The default configuration for the BCM54616S PHY may not match the desired mode when using 1000BaseX or SGMII interface modes, such as when it is on an SFP module. Add code to explicitly set the correct mode using programming sequences provided by Bel-Fuse: https://www.belfuse.com/resources/datasheets/powersolutions/ds-bps-sfp-1gbt-05-series.pdf https://www.belfuse.com/resources/datasheets/powersolutions/ds-bps-sfp-1gbt-06-series.pdf Signed-off-by: Robert Hancock Acked-by: Florian Fainelli Signed-off-by: David S.

net: phy: broadcom: Allow BCM54210E to configure APD

2021-02-15T23:15:25+00:00

BCM54210E/BCM50212E has been verified to work correctly with the auto-power down configuration done by bcm54xx_adjust_rxrefclk(), add it to the list of PHYs working. While we are at it, provide an appropriate name for the bit we are changing which disables the RXC and TXC during auto-power down when there is no energy on the cable.

net: phy: broadcom: Remove unused flags

2021-02-15T23:15:25+00:00

We have a number of unused flags defined today and since we are scarce on space and may need to introduce new flags in the future remove and shift every existing flag down into a contiguous assignment. PHY_BCM_FLAGS_MODE_1000BX was only used internally for the BCM54616S PHY, so we allocate a driver private structure instead to store that flag instead of canibalizing one from phydev->dev_flags for that purpose.

net: phy: broadcom: Avoid forward for bcm54xx_config_clock_delay()

Avoid a forward declaration by moving the callers of bcm54xx_config_clock_delay() below its body. Signed-off-by: Florian Fainelli Reviewed-by: Vladimir Oltean Signed-off-by: David S. Miller

net: phy: introduce phydev->port

2021-02-11T21:09:58+00:00

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.
