From c00125e07c1ebc125bab40e1e18bceed8be0c162 Mon Sep 17 00:00:00 2001 From: Bartlomiej Sieka Date: Sun, 27 May 2007 16:58:45 +0200 Subject: MPC5XXX, Motion-PRO: Fix PHY initialization problem. After being reset in mpc5xxx_fec_init_phy(), PHY goes into FX mode, in which networking does not function. This commit switches PHY to TX mode by clearing the FX_SEL bit of Mode Control Register. It also reverses commit 008861a2f3ef2c062744d733787c7e530a1b8761, i.e., a temporary workaround.
