Subject: [PATCH] ARM: dts: at91-sama5d27_som1: fix phy address to 7
Date: Wed, 17 Feb 2021 12:38:08 +0100 [thread overview]
Message-ID: <20210217113808.21804-1-nicolas.ferre@microchip.com> (raw)
From: Claudiu Beznea <claudiu.beznea@microchip.com>
Fix the phy address to 7 for Ethernet PHY on SAMA5D27 SOM1. No
connection established if phy address 0 is used.
The board uses the 24 pins version of the KSZ8081RNA part, KSZ8081RNA
pin 16 REFCLK as PHYAD bit [2] has weak internal pull-down. But at
reset, connected to PD09 of the MPU it's connected with an internal
pull-up forming PHYAD[2:0] = 7.
