* Remove support for varying offset.
[v9]
* Update the Documentation binding for freq-domain-cells & cpufreq node.
* Address comments in Kconfig.arm & Makefile.
* Remove include file & MODULE_DESCRIPTION not required.
* Fix the code for 'of_node_put(cpu_np)'.
[v8]

the CPU nodes.
* Updated the Documentation for the above change in DT.
* Updated logic for assigning 'qcom_freq_domain_map' for related CPUs.
* Clock input to the HW block is taken from DT which has been updated in
code and Device tree documentation.
[v7]
* Updated the logic to check for related CPUs.
[v6]
* Renamed match table 'qcom_cpufreq_hw_match'.
* Renamed 'qcom_read_lut' to 'qcom_cpufreq_hw_read_lut'.
* Updated the logic to check for related CPUs at the beginning of the
'qcom_cpu_resources_init'.
* Use devm_ioremap_resource instead of devm_ioremap.
* Update the use of of_node_put to handle error conditions.
* Use policy->cached_resolved_idx in fast switch callback.
* Keep precalculated offsets 'reg_bases'.
* XO clock is taken from Device tree.
* Update documentation binding for clocks/clock-names.
* Minor comments in Kconfig.arm.
* Comments to move dev_info to dev_dbg.
[v5]
* Remove mapping different register regions of perf/lut/enable,
instead map the entire HW region.
* Add reg_offset/cpufreq_qcom_std_offsets to be supplied as device data.
* Check of src == 0 during lut read.
* Add of_node_put(cpu_np) in qcom_get_related_cpus
* Update the qcom_cpu_resources_init for register offset data,
and cleanup the related cpus to keep a single copy of CPUfreq.
* Replace FW with HW, update Kconfig, rename filename qcom-cpufreq-hw.c
* Update the documentation binding to reflect the changes of mapping the
* entire HW region.
[v4]
* Fixed console messages as per comments.
* Return error from qcom_resources_init()
in the cases where failed to get frequency domain.
* Rename cpu_dev to cpu_np in qcom_resources_init,
qcom_get_related_cpus(). Also use temp variable freq_np in
qcom_get_related_cpus().
* Update qcom_cpufreq_fw_get() to use the policy data to incoporate
the hotplug use case.
* Update code to use of fast_switching.
* Check for !c->max_cores instead of cpumask_empty in
qcom_get_related_cpus().
* Update the logic of assigning 'c' to qcom_freq_domain_map[cpu].
[v3]
* Remove index check from 'qcom_cpufreq_fw_target_index'.
* Update the Documentation binding to add the platform specific properties in
the CPU nodes, node name "qcom,freq-domain".
* Update return value to '0' from -ENODEV from 'qcom_cpufreq_fw_get'.
* Update the logic for boost frequency to use local variables instead of
cpufreq driver data in 'qcom_read_lut'.
* Update the logic in 'qcom_get_related_cpus' to find the related cpus.
* Update the reg-names to remove "_base" and also update the binding with the
description of these registers.
* Update the logic in 'qcom_resources_init' to address the new device tree
notation of handling the frequency domain phandles.
[v2]
* Fixed the alignment issues in "qcom_cpufreq_fw_target_index" for dev_err and
also for "qcom_cpu_resources_init".
* Removed ret = 0 from qcom_get_related_cpus and added to check for
cpu_mask_empty to return -ENOENT.
* Fixes qcom_cpu_resources_init function
* Remove initialization of 'index'
* Check for valid 'c'
* Removed initialization of 'prev_cc' from 'qcom_read_lut'.
