* MSM Gladiator error reporting driver



Required properties:

- compatible: Should be "qcom,msm-gladiator" or "qcom,msm-gladiator-v2" or

"qcom,msm-gladiator-v3"

- reg: I/O address Gladiator H/W block

- reg-names: Should be "gladiator_base"

- interrupts: Should contain the gladiator error interrupt number

- clock-names: Should be "atb_clk"

- clocks: Handles to clocks specified in "clock-names" property.



Example:



qcom,msm-gladiator-v2@b1c0000 {

	compatible = "qcom,msm-gladiator";

	reg = <0xb1c0000 0xe000>;

	reg-names = "gladiator_base";

	interrupts = <0 34 0>;

	clock-names = "atb_clk";

	clocks = <&clock_gcc clk_qdss_clk>;
