[PATCH 3/5] RapidIO: Modify subsystem and driver initialization sequence
From: Alexandre Bounine <hidden>
Date: 2011-02-28 20:52:32
Also in:
lkml
Subsystem:
linux for powerpc (32-bit and 64-bit), networking drivers, rapidio subsystem, the rest · Maintainers:
Madhavan Srinivasan, Michael Ellerman, Andrew Lunn, "David S. Miller", Eric Dumazet, Jakub Kicinski, Paolo Abeni, Matt Porter, Alexandre Bounine, Linus Torvalds
Subsystem initialization sequence modified to support presence of multiple RapidIO controllers in the system. The new sequence is compatible with initialization of PCI devices.
