    hwspinlock/omap: enable module before reading SYSSTATUS register · e1e4528f
    Suman Anna authored
    The number of hwspinlocks are determined based on the value read
    from the IP block's SYSSTATUS register. However, the module may
    not be enabled and clocked, and the read may result in a bus error.
    
    This particular issue is seen rather easily on AM33XX, since the
    module wakeup is software controlled, and it is disabled out of
    reset. Make sure the module is enabled and clocked before reading
    the SYSSTATUS register.
