2014-11-12net: phy: micrel: disable broadcast for KSZ8081/KSZ8091Johan Hovold1-1/+8
Disable PHY address 0 as the broadcast address, so that it can be used as a unique (non-broadcast) address on a shared bus. Note that this can also be configured using the B-CAST_OFF pin on KSZ9091, but that KSZ8081 lacks this pin and is also limited to addresses 0 and 3. Specifically, this allows for dual KSZ8081 setups.

2014-11-12net: phy: micrel: refactor broadcast disableJohan Hovold1-2/+22
Refactor and clean up broadcast disable. Some Micrel PHYs have a broadcast-off bit in the Operation Mode Strap Override register which can be used to disable PHY address 0 as the broadcast address, so that it can be used as a unique (non-broadcast) address on a shared bus. Note that the KSZPHY_OMSO_RMII_OVERRIDE bit is set by default on KSZ8021/8031. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: David S. Miller <davem@davemloft.net>

2014-11-12net: phy: Correctly handle MII ioctl which changes autonegotiation.Brian Hill1-12/+24
When advertised capabilities are changed with mii-tool, such as: mii-tool -A 10baseT the existing handler has two errors. - An actual PHY register value is provided by mii-tool, and this must be mapped to internal state with mii_adv_to_ethtool_adv_t(). - The PHY state machine needs to be told that autonegotiation has again been performed. If not, the MAC will not be notified of the new link speed and duplex, resulting in a possible config mismatch.

This patch adds support to sync the states of the PCS and the PHY after a reset is performed. If the PCS and the PHY are not in the same state after reset an extra mode change would be performed.

2014-11-05net: phy: spi_ks8995: remove sysfs bin file by registered attributeVladimir Zapolskiy1-1/+3
When a sysfs binary file is asked to be removed, it is found by attribute name, so strictly speaking this change is not a fix, but just in case when attribute name is changed in the driver or sysfs internals are changed, it might be better to remove the previously created file using right the same binary attribute.

2014-10-14phy/micrel: KSZ8031RNL RMII clock reconfiguration bugBruno Thomsen1-1/+3
Bug: Unable to send and receive Ethernet packets with Micrel PHY. Affected devices: KSZ8031RNL (commercial temp) KSZ8031RNLI (industrial temp) Description: PHY device is correctly detected during probe. PHY power-up default is 25MHz crystal clock input and output 50MHz RMII clock to MAC. Reconfiguration of PHY to input 50MHz RMII clock from MAC causes PHY to become unresponsive if clock source is changed after Operation Mode Strap Override (OMSO) register setup. Cause: Long lead times on parts where clock setup match circuit design forces the usage of similar parts with wrong default setup. Solution: Swapped KSZ8031 register setup and added phy_write return code validation. Tested with Freescale i.MX28 Fast Ethernet Controler (fec).

2014-09-08net: phy: mdio-sun4i: don't select REGULATORBeniamino Galvani1-2/+0
The mdio-sun4i driver automatically selects REGULATOR and REGULATOR_FIXED_VOLTAGE because it uses the regulator API. But a driver selecting a subsystem increases the chance of generating circular Kconfig dependencies, especially when other drivers depend on the selected symbol. Since the regulator API functions are replaced with no-ops when REGULATOR is disabled, the driver can be built successfully even without regulator support and so those 'select' dependencies can be safely dropped.

2014-09-06net-timestamp: Make the clone operation stand-alone from phy timestampingAlexander Duyck1-3/+3
The phy timestamping takes a different path than the regular timestamping does in that it will create a clone first so that the packets needing to be timestamped can be placed in a queue, or the context block could be used. In order to support these use cases I am pulling the core of the code out so it can be used in other drivers beyond just phy devices. In addition I have added a destructor named sock_efree which is meant to provide a simple way for dropping the reference to skb exceptions that aren't part of either the receive or send windows for the socket, and I have removed some duplication in spots where this destructor could be used in place of sock_edemux.
