net: phy: Add Wake-on-LAN driver for Microsemi PHYs.

2016-10-07T00:48:04+00:00

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.

2016-10-04T04:47:30+00:00

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.

net: phy: Add MAC-IF driver for Microsemi PHYs.

2016-09-20T08:39:23+00:00

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.

2016-09-10T01:16:10+00:00

The existing VSC85xx PHY driver did not follow the coding style and caused "checkpatch" to complain. This commit fixes this.

net: phy: initialize rc to zero to avoid returning garbage value

2016-08-13T22:51:49+00:00

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.
