    regmap: debugfs: Allow writes to cache state settings · d3dc5430
    Richard Fitzgerald authored Jun 23, 2015 and Mark Brown's avatar Mark Brown committed Jul 20, 2015
    
    
    Allow the user to write the cache_only and cache_bypass settings.
    This can be useful for debugging.
    
    Since this can lead to the hardware getting out-of-sync with the
    cache, at least for the period that the cache state is forced, the
    kernel is tainted and the action is recorded in the kernel log.
    
    When disabling cache_only through debugfs a cache sync will be performed.
