amd-xgbe: Move the PHY support into amd-xgbe

2015-05-15T19:21:43Z

The AMD XGBE device is intended to work with a specific integrated PHY and that PHY is not meant to be a standalone PHY for use by other devices. As such this patch removes the phylib driver and implements the PHY support in the amd-xgbe driver (the majority of the logic from the phylib driver is moved into the amd-xgbe driver). Update the driver version to 1.0.1. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe-phy: Provide support for auto-negotiation timeout

2015-03-20T20:33:56Z

Currently, there is no interrupt code that indicates auto-negotiation has timed out. If the auto-negotiation has timed out then the start of a new auto-negotiation will begin again with a new base page being received. The state machine could be in a state that is not expecting this interrupt code which results in an error during auto-negotiation. Update the code to timestamp when the auto-negotiation starts. Should another page received interrupt code occur before auto-negotiation has completed but after the auto-negotiation timeout, then reset the state machine to allow the auto-negotiation to continue.

amd-xgbe-phy: Use the phy_driver flags field

2015-03-20T20:33:56Z

Remove the setting of the transceiver type when retrieving the device settings using ethtool and instead set the transceiver type in the phy_driver structure flags field. Change the transceiver type to be internal, also. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe-phy: Use phydev advertising field vs supported

2015-03-20T20:33:56Z

With ethtool being able to control what is advertised, the advertising field is what should be used for priming the auto-negotiation registers and for various other checks, instead of the supported field. Also, move the initial setting of the supported and advertising fields into the probe function so that they are not reset each time the device is brought up, thus allowing the user to set as desired before bringing the device up.

amd-xgbe-phy: PHY KX/KR mode differences

2015-02-25T21:57:42Z

The PHY requires different settings for the Decision Feedback Analyzer (DFE) when running in KX mode vs. KR mode. Update the code to change these settings when changing modes in order to provide a more stable link. Additionally, adjust the 10GbE PQ skew default setting to a more sane value.

amd-xgbe-phy: Allow certain PHY settings to be set by UEFI

2015-01-17T03:24:21Z

Certain PHY settings need to be configurable by UEFI depending on the platform being used. Add new device tree / ACPI properties that, if present, will override the pre-determined values currently used. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe: Add ACPI support

2015-01-17T03:24:20Z

Add support for ACPI to the amd-xgbe and amd-xgbe-phy drivers. This support converts many of the device tree APIs to the new device_property APIs. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe-phy: Use the proper auto-negotiation XNP registers

2015-01-17T03:24:20Z

When receiving and processing extended next pages the base registers were used instead of the XNP registers. Update the code to use the device XNP and link partner XNP registers. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe-phy: Properly support the FEC auto-negotiation

2015-01-17T03:24:20Z

Advertise and apply the Forward Error Correction capabilities of the device based on the FEC ability of the device. Also, remove the use of some hard coded values related to KR and FEC in preference of some #defines. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe-phy: Change auto-negotiation logic

2015-01-17T03:24:20Z

The auto negotiation logic was geared to being the initiator of the auto negotiation. This presented problems when auto negotiation was initiated by the remote end. Change the auto negotiation logic to make use of the auto negotiation event interrupt thus allowing the auto negotiation state machine to function properly in either scenario. This also removes the polling during auto-negotiation. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller
