[ARM] 3605/1: AT91RM9200 Power Management
Patch from Andrew Victor This patch adds the core Power Management support for the AT91RM9200 processor. It will support suspend-to-RAM and standby modes. The suspend-to-RAM functionality is not 100% complete. The code that needs to be execute from the internal SRAM to restore the system is outstanding. For now we just fall through to Standby mode. The AT91-specific at91_suspend_entering_slow_clock() function will eventually be replaced by clk_must_disable() once that functionality is added to mainline clock API. Patch from David Brownell.
