Initial irqchip init infrastructure and GIC and VIC clean-ups
This creates irqchip initialization infrastructure from Thomas Petazzoni. The VIC and GIC irqchip code is moved to drivers/irqchips and adapted to use the new infrastructure. All DT enabled platforms using GIC and VIC are converted over to use the new irqchip_init. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.11 (GNU/Linux) iQEcBAABAgAGBQJQ8ZobAAoJEMhvYp4jgsXiihIH/2VvxmSHZb0e3jN6AR0B42b7 9EwX0IE0B23t91hNTwdzzmTJQYA7pMmWkgHNfd3vIeqSepJAmrVv/gp4iM9CtPwE KNh+kDWOK2ZsOH4Vb0lYRJHN8WQOIQHuCUr9+MdYLNOgf/pPL6G/Y9kv9A1e7fTC W+tFRjC5N1ilZMGyowX12L1wnwDk6kHzed6YV6bskC17cZ9/pg8PhSVbM4A/3kAv NXYKqbXJb+eCsWGXg/knZXOL6V9gBwvVYoe4O9X3nQ0226AWB9caad8l8tchAjRB fmrYF1tbkpOWPnLxhvQy5b5MJichJgTMJHh7RgiEcc/3f63kOljjlx4QKiqHvT0= =q7gm -----END PGP SIGNATURE----- Merge tag 'gic-vic-to-irqchip' of git://sources.calxeda.com/kernel/linux into next/cleanup From Rob Herring: Initial irqchip init infrastructure and GIC and VIC clean-ups This creates irqchip initialization infrastructure from Thomas Petazzoni.
