2014-02-12net: phy: use network device in phy_print_statusFlorian Fainelli
phy_print_status() currently uses dev_name(&phydev->dev) which will usually result in printing something along those lines for Device Tree aware drivers: libphy: f0b60000.etherne:0a - Link is Down libphy: f0ba0000.etherne:00 - Link is Up - 1000/Full This is not terribly useful for network administrators or users since we expect a network interface name to be able to correlate link events with interfaces. Update phy_print_status() to use netdev_info() with phydev->attached_dev which is the backing network device for our PHY device. The leading dash is removed since netdev_info() prefixes the messages with "<interface>: " already. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2014-02-12target: Simplify command completion by removing CMD_T_FAILED flagRoland Dreier
The CMD_T_FAILED flag is set used in one place to record the result of a trivial test, and it is only tested once, few lines later. We might as well make the code simpler and easier to read by directly doing the test of "success" where we want to use it.

2014-02-12sfc: Rewrite adjustment of PPS event in a clearer wayBen Hutchings
There is substantial latency in generation and handling of PPS events from the NIC, which we have to correct for before passing a host timestamp to the PPS subsystem. We compare clocks with the MC, giving us two offsets to subtract from the timestamp generated by pps_get_ts(): (a) Time from the last good sync (where we got host and NIC timestamps for nearly the same instant) to the time we called pps_get_ts() (b) Time from NIC top of second to the last good sync We currently calculate (a) + (b) in a quite confusing way. Instead, calculate (a) completely, then add (b) to it. Signed-off-by: Ben Hutchings <bhutchings@solarflare.com> Signed-off-by: Shradha Shah <sshah@solarflare.com> Signed-off-by: David S.

Convert the inline comments to kernel-doc format. Explicitly specify that non-zero autoneg is an error if link autonegotiation is disabled. Specify that pause capabilities should be advertised dependent on link autonegotiation, not the autoneg flag here.

2014-02-12PCI: mvebu: Use Device ID and revision from underlying endpointAndrew Lunn
Marvell SoCs place the SoC number into the PCIe endpoint device ID. The SoC stepping is placed into the PCIe revision. The old plat-orion PCIe driver allowed this information to be seen in user space with a simple lspci command. The new driver places a virtual PCI-PCI bridge on top of these endpoints. It has its own hard coded PCI device ID. Thus it is no longer possible to see what the SoC is using lspci. When initializing the PCI-PCI bridge, set its device ID and revision from the underlying endpoint, thus restoring this functionality. Debian would like to use this in order to aid installing the correct DTB file.
