[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.
