[ Upstream commit 032f85c9360fb1a08385c584c2c4ed114b33c260 ]
Increase the reset duration to ensure correct phy functionality. The reset duration is taken from barebox commit 52fdd510de ("ARM: dts: pfla02: use long enough reset for ethernet phy"):
Use a longer reset time for ethernet phy Micrel KSZ9031RNX. Otherwise a small percentage of modules have 'transmission timeouts' errors like
barebox@Phytec phyFLEX-i.MX6 Quad Carrier-Board:/ ifup eth0 warning: No MAC address set. Using random address 7e:94:4d:02:f8:f3 eth0: 1000Mbps full duplex link detected eth0: transmission timeout T eth0: transmission timeout T eth0: transmission timeout T eth0: transmission timeout T eth0: transmission timeout
