2016-07-04net: ethernet: arc: emac: use phydev from struct net_devicePhilippe Reynes1-1/+0
The private structure contain a pointer to phydev, but the structure net_device already contain such pointer. So we can remove the pointer phy in the private structure, and update the driver to use the one contained in struct net_device.

2016-03-16net: arc: trivial: cleanup the emac driverCaesar Wang1-26/+28
This patch will make the driver more readability The emac has the error and warnings if you run 'scripts/checkpatch.pl -f --subjective xxx' to check. Let's clean up such trivial details.

2016-03-16net: arc_emac: support the phy reset for emac driverCaesar Wang1-0/+6
This patch adds to support the emac phy reset. Different boards may require different phy reset duration. Add property phy-reset-duration for emac driver, so that the boards that need a longer reset duration can specify it in their device tree.

2014-09-09ethernet: arc: Add support for Rockchip SoC layer device tree bindingsRomain Perier1-1/+3
This patch defines a platform glue layer for Rockchip SoCs which support arc-emac driver. It ensures that regulator for the rmii is on before trying to connect to the ethernet controller. It applies right speed and mode changes to the grf when ethernet settings change. Signed-off-by: Romain Perier <romain.perier@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-08-27ethernet: arc: Add support for specific SoC layer device tree bindingsRomain Perier1-0/+4
Some platforms have special bank registers which might be used to select the correct clock or the right mode for Media Indepent Interface controllers. Sometimes, it is also required to activate vcc regulators in the right order to supply the ethernet controller at the right time. This patch is an architecture refactoring of the arc-emac device driver. It adds a new software design which allows to add specific platform glue layer. Each platform has now its own module which performs custom initialization and remove for the target and then calls to the core driver.

2014-08-27ethernet: arc: mdio changes for future SoC glue layer devtree supportRomain Perier1-1/+1
This is an api changes for the emac_mdio.c module. It will be required later when arc_emac_probe/arc_emac_remove will no longer use 'struct platform_device'.

2014-07-09arc_emac: Remove unused pointer to net_device from arc_emac_privTobias Klauser1-2/+0
The pointer to the struct net_device in the private data is only assigned but never used, so delete it. Signed-off-by: Tobias Klauser <tklauser@distanz.ch> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-09arc_emac: Use net_device_stats from struct net_deviceTobias Klauser1-2/+0

2014-04-27arc_emac: add clock handlingHeiko Stübner1-0/+2
This adds ability for the arc_emac to really handle its supplying clock. To get the needed clock-frequency either a real clock or the previous clock-frequency property must be provided.

2013-12-06arc_emac: remove custom "max-speed" parsing codeFlorian Fainelli1-2/+0
The ARC emac driver was the only in-tree to parse a PHY device 'max-speed' property but yet failed to do it correctly because 'max-speed' is supposed to set a PHY device supported features, not the advertising features as it was done. Now that of_mdiobus_register() takes care of doing that, remove the custom 'max-speed' parsing code. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.
