   6           This option enables U-Boot watchdog support where U-Boot is using
   7           watchdog_reset function to service watchdog device in U-Boot. Enable
   8           this option if you want to service enabled watchdog by U-Boot. Disable
   9           this option if you want U-Boot to start watchdog but never service it.

  55           Enable driver model for watchdog timer. At the moment the API
  56           is very simple and only supports four operations:
  57           start, restart, stop and reset (expire immediately).
  58           What exactly happens when the timer expires is up to a particular
  59           device/driver.

  74            There are 4 possible clocks which can be used on these SoCs. This
  75            driver uses the second clock (ID 1), assuming that so will also
