This is my biggest patchset ever and it might not happen again in my entire career. I hope I haven't screwed up here :)
CPUFreq cleanup patches are ready to hit linux-next (I hope it doesn't turn out into horror stories, where it broke all possible architectures where Linux runs :))
Most of these are build tested only, Also done by: Fengguang Wu's build bot.
All of these were sent separately in smaller patchsets earlier and now merged together as a single set. Some parts are reviewed by platform maintainers and their Acks are included in the patches (Sorry if I missed any)..
These are rebased over today's pm/linux-next: f74a274 Merge branch 'pm-cpufreq-next' into linux-next
with following patches over it, which I expect to get into Rafael's tree before these: cpufreq: use correct values of cpus in __cpufreq_remove_dev_finish() cpufreq: distinguish drivers that do asynchronous notifications cpufreq: make sure frequency transitions are serialized cpufreq: Create cpufreq_transition_complete() cpufreq: powernow-k8: mark freq transition complete on error cases
There are few new patches here which haven't been sent yet and only came out after discussions with Maintainers about their platforms: cpufreq: loongson2: use cpufreq_generic_init() routine cpufreq: davinci: use cpufreq_generic_init() routine cpufreq: cris: use cpufreq_generic_init() routine cpufreq: omap: use cpufreq_generic_init() routine
As suggested by Rafael earlier, he might not apply all at once and will give people some chance to test sets one by one.. So, first set now, next one after few days. So, I am marking different sets with patch numbers to make it easier for Rafael.
- Patch 1->8: Generic cleanup of cpufreq core (First batch) - Patch 9->54: Mostly about cpufreq_table_validate_and_show() helper (First batch) - Patch 55->89: New generic routines for cpufreq drivers (First/Second batch) - Patch 90->126: About calling cpufreq_driver->get() from core (First/Second batch) - Patch 127->146: Generic init() routine (First/Second batch) - Patch 147->180: Light weight ->target() routine (Third batch) - Patch 181->211: Call notifiers from core instead of target() (Third/Fourth batch) - Patch 212->228: Generic get() (Fifth batch)
As suggested by Amit here, Linaro may try to test linux-next with these patches on Linaro's board farm (Mostly ARM and X86)..
