     13  BD9576MUF and BD9573MUF are power management ICs primarily intended for
     14  powering the R-Car series processors.
     15  The IC provides 6 power outputs with configurable sequencing and safety
     16  monitoring. A watchdog logic with slow ping/windowed modes is also included.

     36      the PMIC startup. If vout1-en is LOW during PMIC startup then the VOUT1
     37      enable sate is controlled via this pin. Set this property if vout1-en
     38      is wired to be down at PMIC start-up.

     64      Watchog timeout in milliseconds. If single value is given it is

     66      limit the watchdog will be triggered. If two values are given watchdog
     67      is configured in "window mode". Then first value is limit for short-ping
     68      Eg. if watchdog is pinged sooner than that the watchdog will trigger.
     69      When two values is given the second value is the maximum timeout.
     70      # (HW) minimum for short timeout is 2ms, maximum 220 ms.
