From 4d47ea22790dfb85bffbe10492d1767fea9ce79f Mon Sep 17 00:00:00 2001 From: =?utf8?q?Marek=20Beh=C3=BAn?= Date: Wed, 27 Apr 2022 12:41:47 +0200 Subject: [PATCH] net: mvneta: Remember fixed link instead of PHY address in priv data MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit We don't need to remember PHY address anymore, because since using DM MDIO for connecting PHY, the address is parsed by mdio-uclass from the ofnode. But the driver uses a special value of the address to signal fixed link usage. Drop phyaddr add fixed_link in driver private structure. This simplifies code a little.
