+    - compatible : Should be "talitos"
+    - reg : Offset and length of the register set for the device
+    - interrupts : <a b> where a is the interrupt number and b is a

+      information for the interrupt.  This should be encoded based on
+      the information in section 2) depending on the type of interrupt

+    - interrupt-parent : the phandle for the interrupt controller that
+      services interrupts for this device.
+    - num-channels : An integer representing the number of channels

+      should be encoded following the SEC's Descriptor Header Dword

+

+      are available. It's a single 32 bit cell. Descriptor type

+      Header Dword DESC_TYPE field documentation, i.e. as follows:
