Qualcomm Technologies, Inc. CPUFREQ Hardware Debug Bindings

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

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>;

	};
