From c9bca2fe3ca6d6dac2a27eb8619955648369efed Mon Sep 17 00:00:00 2001 From: Xing Zheng Date: Fri, 8 Jan 2016 09:35:00 +0800 Subject: [PATCH] net: ethernet: arc: Probe emac after set RMII clock After enter arc_emac_probe, emac will get_phy_id, phy_poll_reset and other connecting PHY via mdiobus_read, so we need to set correct ref clock rate for emac before probe emac.
