Changelog:
v1 -> v2:
- Modified compatible string to use an enum instead of a generic pattern.
- Updated maintainers list.

+  for the test chip.
+
+  In some cases its registers are also mapped in normal address space
+  and can be used to obtain runtime information about the chip internals
+  (like silicon temperature sensors) and as interface to other subsystems
+  like platform configuration control and power management.

-ARM Versatile Express Serial Configuration Controller
------------------------------------------------------
-
-Test chips for ARM Versatile Express platform implement SCC (Serial
-Configuration Controller) interface, used to set initial conditions
-for the test chip.
-
-In some cases its registers are also mapped in normal address space
-and can be used to obtain runtime information about the chip internals
-(like silicon temperature sensors) and as interface to other subsystems
-like platform configuration control and power management.
-
-Required properties:
-
-- compatible value: "arm,vexpress-scc,<model>", "arm,vexpress-scc";
-		    where <model> is the full tile model name (as used
-		    in the tile's Technical Reference Manual),
-		    eg. for Coretile Express A15x2 A7x3 (V2P-CA15_A7):
-	compatible = "arm,vexpress-scc,v2p-ca15_a7", "arm,vexpress-scc";
-
-Optional properties:
-
-- reg: when the SCC is memory mapped, physical address and size of the
-       registers window
-- interrupts: when the SCC can generate a system-level interrupt
-
-Example:
-
-	scc@7fff0000 {
-		compatible = "arm,vexpress-scc,v2p-ca15_a7", "arm,vexpress-scc";
-		reg = <0 0x7fff0000 0 0x1000>;
-		interrupts = <0 95 4>;
-	};
