From 312aca4e6964812007c8218c0b4b0737e9e0f46a Mon Sep 17 00:00:00 2001 From: Vitaly Andrianov Date: Wed, 11 Feb 2015 14:05:41 -0500 Subject: [PATCH] net: keystone_net: move serdes setup to initialization function On Keystone2 devices serdes must be initialized before accessing MDIO bus. This commit moves the keystone2_net_serdes_setup() from keystone2_eth_open to keystone2_emac_initialize to meet that requirement. This also eliminates unnecessary serdes initializatin every time when the keystone2_eth_open is being called.
