* QCOM LLCC PMU Bindings



This represents the miss counters located in the LLCC hardware counters.

Only one event is supported:



 0x1000      	  - LLCC misses



The follow section describes the LLCC PMU DT node binding.



Required properties:

- compatible		: Shall be "qcom,qcom-llcc-pmu"

- reg			: There shall be two resources, each a pair of the form

			  < base_address total_size >.  One will represent the

			  DDR LAGG region, the other will represent the LLCC

			  BEAC region.

- reg-names		: There shall be two values, one 'lagg-base', one

			  'beac-base', corresponding to the order of the two

			  'reg' values.



Example:

	llcc_pmu: llcc-pmu {

		compatible = "qcom,qcom-llcc-pmu";

		reg = < 0x090CC000 0x300 >, < 0x09648000 0x110 >;

		reg-names = "lagg-base", "beac-base";

	};
