DP83640: DP83640 - linux device tree support

Part Number: DP83640

Hi,
We are using DP83640 PHY chip for our ATMEL SAMA5D36 board ( for eth0 and eth1 )

The kernel updated output log:

macb f0028000.ethernet: invalid hw address, using random
libphy: MACB_mii_bus: probed
pps pps0: new PPS source ptp0
macb f0028000.ethernet eth0: Cadence GEM rev 0x00020119 at 0xf0028000 irq 51 (5e:6c:b0:c1:a4:8b)
macb f0028000.ethernet eth0: attached PHY driver [NatSemi DP83640] (mii_bus:phy_addr=f0028000.etherne:01, irq=-1)


macb f802c000.ethernet: invalid hw address, using random
libphy: MACB_mii_bus: probed
pps pps1: new PPS source ptp1
macb f802c000.ethernet eth1: Cadence MACB rev 0x0001010c at 0xf802c000 irq 52 (be:00:92:fd:15:0b)
macb f802c000.ethernet eth1: attached PHY driver [NatSemi DP83640] (mii_bus:phy_addr=f802c000.etherne:05, irq=-1)

Kindly guide us on how to use/update dp83640 related configuration with the device tree. Basically we are planning to implement PTP with PPS support..We require relevant support to update and configure PTP in linux...

thanks
