--------------------------------------------------------------------

CPUFREQ HW debug provide support to print the CPUFREQ_HW debug
registers.

Required Properties:
- compatible: shall contain the following:
		"qcom,cpufreq-hw-debug" or "qcom,cpufreq-hw-epss-debug".
- reg: shall contain base register location and length.
- reg-names: shall contain the frequency domain name.

Optional Properties:
- qcom,freq-hw-domain: phandle to the frequency domain device node.

Usage :
The following debug node would get created under qcom-cpufreq-hw directory.

- print_cpufreq_debug_regs
Function:	Print cpufreq hardware debug registers
Input:		cat print_cpufreq_debug_regs

Example:
	cpufreq_hw_debug: qcom,cpufreq-hw-debug@18591000 {
		compatible = "qcom,cpufreq-hw-debug";
		reg = <0x18591000 0x800>;
		reg-names = "domain-top";
		qcom,freq-hw-domain = <&cpufreq_hw 0>, <&cpufreq_hw 1>,
					<&cpufreq_hw 2>;
	};
