DCMI Power Get Limits
    [Documentation]  Run dcmi power get_limit and return values as a
    ...  dictionary.

    # This keyword packages the five lines returned by dcmi power get_limit
    # command into a dictionary.  For example, the dcmi command may return:
    #  Current Limit State: No Active Power Limit
    #  Exception actions:   Hard Power Off & Log Event to SEL
    #  Power Limit:         500   Watts
    #  Correction time:     0 milliseconds
    #  Sampling period:     0 seconds
    # The power limit setting can be obtained with the following:
    # &{limits}=  DCMI Power Get Limits
    # ${power_setting}=  Set Variable  ${limits['power_limit']}
