From 529a6712795a50d68967cbd071edfe232a245d5d Mon Sep 17 00:00:00 2001 From: Fabio Estevam Date: Mon, 1 Feb 2016 11:15:10 -0200 Subject: mx6slevk: Fix the reset delay for the the LAN8720 PHY Since commit 59370f3fcd1350 ("net: phy: delay only if reset handler is registered") Ethernet is no longer functional. This commit does not have an issue in itself, but it revelead a problem with the Ethernet initialization. According to the LAN8720 datasheet tpurstd (time that reset line should stay asserted) is 25ms. So do as suggested in order to have Ethernet working again.
