The device tps65910/tps65911 supports the sleep functionality in some of gpios. If gpio is configured in output mode and sleep is enabled then during device sleep state, the output of gpio becomes LOW regardless of non-sleep output value. Such gpio can be used to control regulator switch such that output of regulator is off in device sleep state.

2012-02-15cache-v7: Disable preemption when reading CCSIDRStephen Boyd
armv7's flush_cache_all() flushes caches via set/way. To determine the cache attributes (line size, number of sets, etc.) the assembly first writes the CSSELR register to select a cache level and then reads the CCSIDR register. The CSSELR register is banked per-cpu and is used to determine which cache level CCSIDR reads. If the task is migrated between when the CSSELR is written and the CCSIDR is read the CCSIDR value may be for an unexpected cache level (for example L1 instead of L2) and incorrect cache flushing could occur. Disable interrupts across the write and read so that the correct cache attributes are read and used for the cache flushing routine. We disable interrupts instead of disabling preemption because the critical section is only 3 instructions and we want to call v7_dcache_flush_all from __v7_setup which doesn't have a full kernel stack with a struct thread_info. This fixes a problem we see in scm_call() when flush_cache_all() is called from preemptible context and sometimes the L2 cache is not properly flushed out.
