ARM: dts: pfla02: increase phy reset duration
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 Cc: Stefan Christ <s.christ@phytec.de> Cc: Christian Hemp <c.hemp@phytec.de> Signed-off-by: Marco Felsch <m.felsch@pengutronix.de> Fixes: 3180f956668e ("ARM: dts: Phytec imx6q pfla02 and pbab01 support") Signed-off-by: Shawn Guo <shawnguo@kernel.org>
