+ARM Versatile system registers
+--------------------------------------
+
+This is a system control registers block, providing multiple low level
+platform functions like board detection and identification, software
+interrupt generation, MMC and NOR Flash control etc.
+
+Required node properties:
+- compatible value : = "arm,versatile-sysreg", "syscon"
+- reg : physical base address and the size of the registers window

+- compatible : should be "cnxt,cx92755-timer"
+- reg : Specifies base physical address and size of the "Agent Communication"
+  timer registers
+- interrupts : Contains 8 interrupts, one for each timer
