* net: phy: Add Wake-on-LAN driver for Microsemi PHYs.Raju Lakkaraju2016-10-061-0/+128
| | | | | | | | | | | | | Wake-on-LAN (WoL) is an Ethernet networking standard that allows a computer/device to be turned on or awakened by a network message. VSC8531 PHY can support this feature configure by driver set function. WoL status get by driver get function. Tested on Beaglebone Black with VSC 8531 PHY.

* net: phy: Add Edge-rate driver for Microsemi PHYs.Raju Lakkaraju2016-10-041-0/+125
| | | | | | | | | | | | | | | | | | | | | | | | Edge-rate: As system and networking speeds increase, a signal's output transition, also know as the edge rate or slew rate (V/ns), takes on greater importance because high-speed signals come with a price. That price is an assortment of interference problems like ringing on the line, signal overshoot and undershoot, extended signal settling times, crosstalk noise, transmission line reflections, false signal detection by the receiving device and electromagnetic interference (EMI) -- all of which can negate the potential gains designers are seeking when they try to increase system speeds through the use of higher performance logic devices. The fact is, faster signaling edge rates can cause a higher level of electrical noise or other type of interference that can actually lead to slower line speeds and lower maximum system frequencies. This parameter allow the board designers to change the driving strange, and thereby change the EMI behavioral. Edge-rate parameters (vddmac, edge-slowdown) get from Device Tree. Tested on Beaglebone Black with VSC 8531 PHY. Signed-off-by: Raju Lakkaraju <Raju.Lakkaraju@microsemi.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: phy: Add MAC-IF driver for Microsemi PHYs.Raju Lakkaraju2016-09-201-0/+51
| | | | | | | | | | | | | | All the review comments updated and resending for review. This is MAC interface feature. Microsemi PHY can support RGMII, RMII or GMII/MII interface between MAC and PHY. MAC-IF function program the right value based on Device tree configuration. Tested on Beaglebone Black with VSC 8531 PHY.

* net: phy: Fixed checkpatch errors for Microsemi PHYs.Raju Lakkaraju2016-09-091-89/+89
| | | | | | | The existing VSC85xx PHY driver did not follow the coding style and caused "checkpatch" to complain. This commit fixes this. Signed-off-by: Raju Lakkaraju <Raju.Lakkaraju@microsemi.com> Signed-off-by: David S. Miller <davem@davemloft.net>
* net: phy: initialize rc to zero to avoid returning garbage valueColin Ian King2016-08-131-1/+1
| | | | | | | | | In the case where phydev->interrupts is not PHY_INTERRUPT_ENABLED function vsc85xx_ack_interrupt is returning an uninitialized garbage value. Fix this by initializing rc to zero.
