From 7f0e1003bf21ffc5afb9729d386bd94afa67ae9a Mon Sep 17 00:00:00 2001 From: blogic Date: Wed, 23 Mar 2016 12:52:12 +0000 Subject: [PATCH] ar71xx: Use private version of ath79_setup_qca955x_eth_cfg for MR1750 The MR1750 must unset some bits in ETH_CFG which were set by u-boot to work correctly under OpenWrt. But the global function ath79_setup_qca955x_eth_cfg will not unset all of them to increase the backward compatiblity with older mach-* files. A private (simplified) version for MR1750 can be used instead.
