| |
arch_cpu_idle() is a very simple idle interface and exposes only a single idle state and is expected to not require RCU and not do any tracing/instrumentation.
As such, omap_sram_idle() is not a valid implementation. Replace it with the simple (shallow) omap3_do_wfi() call. Leaving the more complicated idle states for the cpuidle driver.
