net: phy: Add LED mode driver for Microsemi PHYs.

2017-02-08T18:29:04Z

LED Mode: Microsemi PHY support 2 LEDs (LED[0] and LED[1]) to display different status information that can be selected by setting LED mode. LED Mode parameter (vsc8531, led-0-mode) and (vsc8531, led-1-mode) get from Device Tree. Signed-off-by: Raju Lakkaraju Signed-off-by: David S. Miller

dt: bindings: net: use boolean dt properties for eee broken modes

2016-12-20T18:50:50Z

The patches regarding eee-broken-modes was merged before all people involved could find an agreement on the best way to move forward. While we agreed on having a DT property to mark particular modes as broken, the value used for eee-broken-modes mapped the phy register in very direct way. Because of this, the concern is that it could be used to implement configuration policies instead of describing a broken HW. In the end, having a boolean property for each mode seems to be preferred over one bit field value mapping the register (too) directly.

net: phy: Cleanup the Edge-Rate feature in Microsemi PHYs.

2016-10-14T14:06:13Z

Edge-Rate cleanup include the following: - Updated device tree bindings documentation for edge-rate - The edge-rate is now specified as a "slowdown", meaning that it is now being specified as positive values instead of negative (both documentation and implementation wise). - Only explicitly documented values for "vsc8531,vddmac" and "vsc8531,edge-slowdown" are accepted by the device driver. - Deleted include/dt-bindings/net/mscc-phy-vsc8531.h as it was not needed. - Read/validate devicetree settings in probe instead of init Signed-off-by: Allan W.

net: phy: Add Edge-rate driver for Microsemi PHYs.

2016-10-04T04:47:30Z

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 Signed-off-by: David S. Miller
