-Security Module (SECUMOD)
-
-The Security Module macrocell provides all necessary secure functions to avoid
-voltage, temperature, frequency and mechanical attacks on the chip. It also
-embeds secure memories that can be scrambled.
-
-The Security Module also offers the PIOBU pins which can be used as GPIO pins.
-Note that they maintain their voltage during Backup/Self-refresh.
-
-required properties:
-- compatible: Should be "atmel,<chip>-secumod", "syscon".
-  <chip> can be "sama5d2".
-- reg: Should contain registers location and length
-- gpio-controller:	Marks the port as GPIO controller.
-- #gpio-cells:		There are 2. The pin number is the
-			first, the second represents additional
-			parameters such as GPIO_ACTIVE_HIGH/LOW.
