+== Introduction==
+
+LLCC (Last Level Cache Controller) provides last level of cache memory in SOC,
+that can be shared by multiple clients. Clients here are different cores in the
+SOC, the idea is to minimize the local caches at the clients and migrate to
+common pool of memory. Cache memory is divided into partitions called slices
+which are assigned to clients. Clients can query the slice details, activate
+and deactivate them.
+
+Properties:
+- compatible:
+ Usage: required
+ Value type: <string>
+ Definition: must be "qcom,sdm845-llcc"
+
+- reg:
+ Usage: required
+ Value Type: <prop-encoded-array>
+ Definition: Start address and the the size of the register region.
+
+Example:
+
+ cache-controller@1100000 {
+ compatible = "qcom,sdm845-llcc";
+ reg = <0x1100000 0x250000>;
+ };
