Subject: arm: socfpga: soc64: Remove PHY interface setup from misc arch init
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=464ca99f8e8ea43e31cffc6dcf026520c8de0609;p=u-boot.git

arm: socfpga: soc64: Remove PHY interface setup from misc arch init

'dwmac_socfpga' driver will setup the PHY interface during probe.
PHY interface setup in arch_misc_init() is no longer needed.
