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

2021-03-30T12:32:05+00:00

[ Upstream commit b1dd9bf688b0dcc5a34dca660de46c7570bd9243 ] 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: Set proper 1000BaseX/SGMII interface mode for BCM54616S

2021-03-30T12:32:05+00:00

[ Upstream commit 3afd0218992a8d1398e9791d6c2edd4c948ae7ee ] 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: 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: broadcom: Add power down exit reset state delay

2021-03-30T12:31:58+00:00

[ Upstream commit 7a1468ba0e02eee24ae1353e8933793a27198e20 ] 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: Wire suspend/resume for BCM54810

2020-02-20T00:36:48+00:00

The BCM54810 PHY can use the standard BMCR Power down suspend, but needs a custom resume routine which first clear the Power down bit, and then re-initializes the PHY. While in low-power mode, the PHY only accepts writes to the BMCR register. The datasheet clearly says it: Reads or writes to any MII register other than MII Control register (address 00h) while the device is in the standby power-down mode may cause unpredictable results.
