[Qemu-ppc] [PATCH 03/15] ohci: Allow sysbus version to be used as a comp


From: BALATON Zoltan
Subject: [Qemu-ppc] [PATCH 03/15] ohci: Allow sysbus version to be used as a companion
Date: Sun, 20 Aug 2017 19:23:05 +0200

Some PPC SoCs have an EHCI with OHCI companion USB controller. To
emulate this allow the sysbus version of OHCI to be used as a companion.
