+		};
+
+		qcom,llcc-ecc {
+			compatible = "qcom,llcc-ecc";
+		};
+
+		qcom,llcc-amon {
+			compatible = "qcom,llcc-amon";
+			qcom,fg-cnt = <0x7>;
+		};
+
+	};

The "qcom,llcc-ecc" and "qcom,llcc-amon" bindings doesn't seem to be
used by the driver in patch 2, and it's not clear how they are intended
to be used, so I think they should go from the binding for now.

I don't think you need syscon and simple-mfd, and I think you can
simplify the binding to a single node like:

	qcom,system-cache at 1300000 {
		compatible = "qcom,sdm845-llcc";
		reg = <0x1300000 0x50000>;
		#cache-slice-cells = <1>;
		max-slices = <32>;
	}

If ECC and AMON are option features, we can always add boolean
properties for those later, e.g. "has-ecc".

Thanks,
Mark.
