From 221c3a09ddf70a0a51715e6c2878d8305e95c558 Mon Sep 17 00:00:00 2001 From: Claudiu Beznea Date: Wed, 11 Apr 2018 19:05:03 +0300 Subject: ARM: dts: at91-sama5d27_som1: fix phy address to 7 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.

The previous value would permit just configuring with function C.

Too much functions for pins were disabled leading to misunderstandings when enabling more peripherals or taking this table as an example for another board. Take advantage of this fix to move the mux-mask in the SoC file where it belongs and use lower case letters for hex numbers like everywhere in the file.
