| Subject: ARM: dts: pfla02: increase phy reset duration |
| |
| [ 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 |
