+* ARM L2 Cache Controller
+
+ARM cores often have a separate level 2 cache controller. There are various
+implementations of the L2 cache controller with compatible programming models.
+The ARM L2 cache representation in the device tree should be done as follows:
+
+Required properties:
+
+- compatible : should be one of:
+ "arm,pl310-cache"
+ "arm,l220-cache"
+ "arm,l210-cache"
+- cache-unified : Specifies the cache is a unified cache.
+- cache-level : Should be set to 2 for a level 2 cache.
+- reg : Physical base address and size of cache controller's memory mapped
+ registers.
+
+Optional properties:
+
+- arm,data-latency : Cycles of latency for Data RAM accesses. Specifies 3 cells of
+ read, write and setup latencies. Minimum valid values are 1. Controllers
+ without setup latency control should use a value of 0.
+- arm,tag-latency : Cycles of latency for Tag RAM accesses. Specifies 3 cells of
+ read, write and setup latencies. Controllers without setup latency control
+ should use 0. Controllers without separate read and write Tag RAM latency
+ values should only use the first cell.
+- arm,dirty-latency : Cycles of latency for Dirty RAMs. This is a single cell.
+- arm,filter-ranges : <start length> Starting address and length of window to
+ filter. Addresses in the filter window are directed to the M1 port. Other
+ addresses will go to the M0 port.
+- interrupts : 1 combined interrupt.
+
+Example:
+
+L2: cache-controller {
+ compatible = "arm,pl310-cache";
+ reg = <0xfff12000 0x1000>;
+ arm,data-latency = <1 1 1>;
+ arm,tag-latency = <2 2 2>;
+ arm,filter-latency = <0x80000000 0x8000000>;
+ cache-unified;
+ cache-level = <2>;
+ interrupts = <45>;
+};
