[PATCH v11 0/2] cpufreq: qcom-hw: Add support for QCOM cpufreq HW

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



 [v11]
   * Updated the code logic as per Stephen.
   * Default boost enabled is removed.
   * Update the clock name to use "alternate" for GPLL0 source in code and
     Documentation binding.
   * Module description updated.
   * perf_base updated to perf_state_reg.

 [v10]
  * Update Documentation binding for cpufreq node.
  * Make the driver 'tristate' instead of 'bool' and update code.
  * Update the clock name to reflect the hardware name.
  * 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]
   * Address comments to update code to take cpufreq_hw phandle and index from
     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'.
