-Subject: [PATCH 235/247] clk: at91: pmc: execute suspend/resume only for
- backup mode
-
-Before going to backup mode architecture specific PM code sets the first
-word in securam (file arch/arm/mach-at91/pm.c, function at91_pm_begin()).
-Thus take this into account when suspending/resuming clocks. This will
-avoid executing unnecessary instructions when suspending to non backup
-modes.
