net: ethernet: altera: TSE: do not use tx queue lock in tx completion handler

2016-12-02T17:10:25+00:00

The driver already uses its private lock for synchronization between xmit
and xmit completion handler making the additional use of the xmit_lock
unnecessary.
Furthermore the driver does not set NETIF_F_LLTX resulting in xmit to be
called with the xmit_lock held and then taking the private lock while xmit
completion handler does the reverse, first take the private lock, then the
xmit_lock.
Fix these issues by not taking the xmit_lock in the tx completion handler.

net: ethernet: altera: TSE: Remove unneeded dma sync for tx buffers

2016-12-02T17:10:24+00:00

An explicit dma sync for device directly after mapping as well as an
explicit dma sync for cpu directly before unmapping is unnecessary and
costly on the hotpath. So remove these calls.

net: ethernet: altera: fix fixed-link phydev leaks

2016-11-30T04:17:02+00:00

Make sure to deregister and free any fixed-link PHY registered using
of_phy_register_fixed_link() on probe errors and on driver unbind.

ethernet: altera: add missing of_node_put

2016-08-02T04:42:57+00:00

of_node_put needs to be called when the device node which is got
from of_parse_phandle (or of_node_get) has finished using.

net: ethernet: altera_tse: use phy_ethtool_{get|set}_link_ksettings

2016-06-22T20:22:41+00:00

There are two generics functions phy_ethtool_{get|set}_link_ksettings,
so we can use them instead of defining the same code in the driver.

net: ethernet: altera_tse: use phydev from struct net_device

2016-06-22T20:22:41+00:00

The private structure contain a pointer to phydev, but the structure
net_device already contain such pointer. So we can remove the pointer
phydev in the private structure, and update the driver to use the
one contained in struct net_device.

net: eth: altera: do not free array priv->mdio->irq

2016-03-07T03:59:18+00:00

priv->mdio->irq used to be allocated and required freeing, but it
is now a fixed sized array and should no longer be free'd.

phy: Add an mdio_device structure

2016-01-07T19:31:26+00:00

Not all devices attached to an MDIO bus are phys. So add an
mdio_device structure to represent the generic parts of an mdio
device, and place this structure into the phy_device.

mdio: Move allocation of interrupts into core

2016-01-07T19:31:26+00:00

Have mdio_alloc() create the array of interrupt numbers, and
initialize it to POLLING. This is what most MDIO drivers want, so
allowing code to be removed from the drivers.
