Subject: [PATCH AUTOSEL 4.14 13/43] ARM: dts: pfla02: increase phy reset duration
Date: Mon, 22 Apr 2019 15:46:57 -0400	[thread overview]
Message-ID: <20190422194727.12495-13-sashal@kernel.org> (raw)
In-Reply-To: <20190422194727.12495-1-sashal@kernel.org>

From: Marco Felsch <m.felsch@pengutronix.de>

[ 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
