m4m-hwmon is a device that represents the MSM M4M hardware monitors
that can be used to measure the various types of requests in the MSM M4M.

- compatible: Must be "qcom,m4m-hwmon"
- reg: Pairs of physical base addresses and region sizes of
memory mapped registers.
- interrupts: Lists the threshold IRQ.
- qcom,counter-event-sel: Array of counter and event selection values.
- qcom,target-dev: The DT device that is monitored by this MSM M4M
counter configuration.
Example:
qcom,m4m-hwmon {
compatible = "qcom,m4m-hwmon";
reg = <0x6530000 0x160>;
interrupts = <0 19 4>;
qcom,counter-event-sel = <4 0x100>;
qcom,target-dev = <&m4m_cache>;
};
