* net: phy: marvell: Only configure RGMII delays when using RGMIIAndrew Lunn2017-11-011-3/+5
| | | | | | | | | | | | | | | | The fix 5987feb38aa5 ("net: phy: marvell: logical vs bitwise OR typo") uncovered another bug in the Marvell PHY driver, which broke the Marvell OpenRD platform. It relies on the bootloader configuring the RGMII delays and does not specify a phy-mode in its device tree. The PHY driver should only configure RGMII delays if the phy mode indicates it is using RGMII. Without anything in device tree, the mv643xx Ethernet driver defaults to GMII.

| | | | | | | | | | | | | | | | | When an Marvell 88E1512 PHY is connected to a nic in SGMII mode, the fiber page is used for the SGMII host-side connection. The PHY driver notices that SUPPORTED_FIBRE is set, so it tries reading the fiber page for the link status, and ends up reading the MAC-side status instead of the outgoing (copper) link. This leads to incorrect results reported via ethtool. If the PHY is connected via SGMII to the host, ignore the fiber page. However, continue to allow the existing power management code to suspend and resume the fiber page. Fixes: 6cfb3bcc0641 ("Marvell phy: check link status in case of fiber link.")
