+Description:
+               This entry shows and sets the maximum time the max14577
+               charger operates in fast-charge mode. When the timer expires
+               the device will terminate fast-charge mode (charging current
+               will drop to 0 A) and will trigger interrupt.
+
+               Valid values:
+               - 5, 6 or 7 (hours),
+               - 0: disabled.
