From b413643a5cdac809a1374481c990387b732f9e60 Mon Sep 17 00:00:00 2001 From: Jean-Christophe Dubois Date: Mon, 30 May 2016 19:25:53 +0200 Subject: [PATCH] i.MX: Fix FEC code for MDIO address selection According to the FEC chapter of i.MX25 reference manual When writing to MMFR register, the MDIO device and adress are selected by bit 27 to 23 and bit 22 to 18 respectively. This is a total of 10 bits that need to be used by the Phy chip/address decoding function. This patch fixes the number of bits used from 9 to 10.
