amd-xgbe: Unify coherency checking logic with device_dma_is_coherent()

2015-06-15T12:40:49Z

Currently, amd-xgbe driver has separate logic to determine device coherency for DT vs. ACPI. This patch simplifies the code with a call to device_dma_is_coherent(). Signed-off-by: Tom Lendacky Signed-off-by: Suravee Suthikulpanit Signed-off-by: Rafael J. Wysocki

amd-xgbe: Remove manual check and set of dma_mask pointer

2015-05-15T19:21:44Z

The underlying device support will set the device dma_mask pointer if DMA is set up properly for the device. Remove the check for and assignment of dma_mask when it is null. Instead, just error out if the dma_set_mask_and_coherent function fails because dma_mask is null. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe: Support defining PHY resources in ETH device node

2015-05-15T19:21:43Z

Simplify the device tree support of the amd-xgbe driver by defining the PHY-related resources within the ethernet device node. The support provides backwards compatibility with the original way. Update the driver version to 1.0.2. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

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: Add netif_* message support to the driver

2015-05-15T19:21:43Z

Add support for the network interface message level settings for determining whether to issue some of the driver messages. Make use of the netif_* interface where appropriate. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe: Add support for the netdev Tx watchdog

2015-04-09T21:35:37Z

Add support to be able to detect a hung Tx task by adding the netdev ndo_tx_timeout function callback. Do not set the watchdog_timeo value so as to use the system default time (currently 5 seconds). Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller

amd-xgbe: Set DMA mask based on hardware register value

2015-03-20T20:33:57Z

The hardware supplies a value that indicates the DMA range that it is capable of using. Use this value rather than hard-coding it in the driver. 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: Clear all state during a device restart

2015-01-17T03:24:20Z

When performing a device restart, like during an MTU change, sometimes the device queues still have data and get hung up trying to flush resulting in the device becoming unresponsive until brought down and back up. To prevent this, always perform a device reset during a restart. Signed-off-by: Tom Lendacky Signed-off-by: David S. Miller
