[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'.
