[PATCH 4.4 077/137] ARM: dts: at91: sama5d4 xplained: properly mux phy interrupt

From: Alexandre Belloni <alexandre.belloni@free-electrons.com>

commit f505dba762ae826bb68978a85ee5c8ced7dea8d7 upstream.

No interrupt were received from the phy because PIOE 1 may not be properly
muxed. It prevented proper link detection, especially since commit
321beec5047a ("net: phy: Use interrupts when available in NOLINK state")
disables polling.
