From f2028bdf06f45955f93cbba8d0a5b5e47be0f359 Mon Sep 17 00:00:00 2001 From: Florian Fainelli Date: Mon, 8 Oct 2012 15:11:30 +0200 Subject: MIPS: PNX8550: use OHCI platform driver Change the PNX8550 platform code to register an ohci-platform driver instead of ohci-pnx8550 since the ohci-platform is suitable for use.
