From fbe17867daddf76ec26be7dbf6b9af3cfad4a54f Mon Sep 17 00:00:00 2001 From: David Bauer Date: Mon, 6 Aug 2018 16:21:03 +0200 Subject: kernel: allow device-tree configuration of at803x This commit adds the ability to configure specific functions of the at803x series ethernet-PHYs, which were previously configured exclusively with the help of platform-data, via device-tree. This is needed to fully support existing boards of the ar71xx platform.
