PM / OPP: Add debugfs support This patch adds debugfs support to OPP layer to export OPPs and their properties for all the devices. This creates a top level directory: /sys/kernel/debug/opp and then device specific directories (based on device names) inside it. For example: 'cpu0', 'cpu1', etc.. If multiple devices share the OPP table, then the real directory is created only for the first device. For all others, links are created to the real directory. Inside the device specific directory, a separate directory is created for each OPP. And within that files per opp property.

PM / OPP: Rename structures for clarity Stephen pointed out recently, that few structures always confuse him as they aren't named properly.

PM / OPP: "opp-hz" is optional for power domains "opp-hz" property is optional for power domains now and we shouldn't error out if it is missing for power domains. This patch creates two new routines, _get_opp_count() and _opp_is_duplicate(), by separating existing code from their parent functions. Also skip duplicate OPP check for power domain OPPs as they may not have any the "opp-hz" field, but a platform specific performance state binding to uniquely identify OPP nodes. By default the debugfs OPP nodes are named using the "rate" value, but that isn't possible for the power domain OPP nodes and hence they use the index of the OPP node in the OPP node list instead.

PM / OPP: Support updating performance state of device's power domain The genpd framework now provides an API to request device's power domain to update its performance state. Use that interface from the OPP core for devices whose power domains support performance states. Note that this commit doesn't add any mechanism by which performance states are made available to the OPP core. That would be done by a later commit. Note that the current implementation is restricted to the case where the device doesn't have separate regulators for itself. We shouldn't over engineer the code before we have real use case for them. We can always come back and add more code to support such cases later on.

PM / OPP: Rename structures for clarity Stephen pointed out recently, that few structures always confuse him as they aren't named properly. And this patch tries to address that: Names are updated as: - device_opp or dev_opp -> opp_table - dev_opp_list -> opp_tables - dev_opp_list_lock -> opp_table_lock - device_list_opp -> opp_device (it was never a list, but a structure) - list_dev -> opp_dev - And similar changes in comments and function names as well.

PM / OPP: Add debugfs support This patch adds debugfs support to OPP layer to export OPPs and their properties for all the devices. This creates a top level directory: /sys/kernel/debug/opp and then device specific directories (based on device names) inside it. For example: 'cpu0', 'cpu1', etc.. If multiple devices share the OPP table, then the real directory is created only for the first device. For all others, links are created to the real directory.

If multiple devices share the OPP table, then the real directory is created only for the first device. For all others, links are created to the real directory. Inside the device specific directory, a separate directory is created for each OPP. And within that files per opp property.

PM / OPP: Rename structures for clarity Stephen pointed out recently, that few structures always confuse him as they aren't named properly. And this patch tries to address that: Names are updated as: - device_opp or dev_opp -> opp_table - dev_opp_list -> opp_tables - dev_opp_list_lock -> opp_table_lock - device_list_opp -> opp_device (it was never a list, but a structure) - list_dev -> opp_dev - And similar changes in comments and function names as well. This also fixes checkpatch warnings that were generated with this patch. No functional changes.

PM / OPP: Add debugfs support This patch adds debugfs support to OPP layer to export OPPs and their properties for all the devices. This creates a top level directory: /sys/kernel/debug/opp and then device specific directories (based on device names) inside it. For example: 'cpu0', 'cpu1', etc.. If multiple devices share the OPP table, then the real directory is created only for the first device. For all others, links are created to the real directory. Inside the device specific directory, a separate directory is created for each OPP. And within that files per opp property.
