-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: The first element specifies the llcc base start address and
-		    the size of the register region. The second element specifies
-		    the llcc broadcast base address and size of the register region.
-
-- reg-names:
-        Usage: required
-        Value Type: <stringlist>
-        Definition: Register region names. Must be "llcc_base", "llcc_broadcast_base".
-
-- interrupts:
-	Usage: required
-	Definition: The interrupt is associated with the llcc edac device.
-			It's used for llcc cache single and double bit error detection
-			and reporting.
-
-Example:
-
-	cache-controller@1100000 {
-		compatible = "qcom,sdm845-llcc";
-		reg = <0x1100000 0x200000>, <0x1300000 0x50000> ;
