    PM / OPP: Add debugfs support · deaa5146
    Viresh Kumar authored
    This patch adds debugfs support to OPP layer to export OPPs and their
    properties for all the devices.
    
    This creates a top level directory: /sys/kernel/debug/opp and then
    device specific directories (based on device names) inside it. For
    example: 'cpu0', 'cpu1', etc..
    
    If multiple devices share the OPP table, then the real directory is
    created only for the first device. For all others, links are created to
    the real directory.
    
    Inside the device specific directory, a separate directory is created
    for each OPP. And within that files per opp property.
