Pull another power sequencing update from Bartosz Golaszewski: "A single tree-wide rename of two of the public functions to better reflect their actual semantics: - rename pwrseq_power_on/off() to pwrseq_enable/disable() tree-wide" * tag 'pwrseq-updates-for-v7.3-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux: power: sequencing: rename pwrseq_power_on/off() to pwrseq_enable/disable()

power: sequencing: rename pwrseq_power_on/off() to pwrseq_enable/disable()

2026-08-26T08:05:45+00:00

The way power sequencing works means that a call to pwrseq_power_on() does not necessarily result in the pwrseq target being powered-on at that time: it may have already been powered on before. Similarly: a call to pwrseq_power_off() does not have to result in an actual powering off of resources: there may still be other users that requested a power-on before. We will also introduce the concept of "non-controllable" pwrseq targets soon which further increases the disconnect between the naming convention and the actual semantics. What consumers of pwrseq descriptors actually do is: they *vote* for a powering on of a given target or retract that vote. These operations could be called get/put in line with runtime PM but this could become confusing since we already provide pwrseq_get/put() for a different purpose. pwrseq_vote_on/off() also have been rejected as unusual in the tree. Change the name of the two functions to pwrseq_enable/disable() which better reflects their purpose and semantics and also mirrors other enable-counted resources like regulators and clocks. No functional change intended. If at any point users need to know *when* the exact power event happens, we can provide that information in the form of a notifier.

headers: Remove swap.h from suspend.h

2026-08-25T19:12:26+00:00

Nothing in suspend.h needs swap.h. However, many files indirectly depend on some of swap.h's dependencies, so this is a large cross-subsystem patch. Stats: 42 are missing includes of interrupt.h (the question of why swap.h brings in interrupt.h remains unanswered). 10 missing includes of seq_file.h 5 missing includes of swap.h (obviously all files could have just added swap.h, but I preferred to bring in a more minimal inclusion set) 3 missing includes of highmem.h 2 missing includes of device.h 2 missing includes of string_choices.h 1 missing include of cacheflush.h 1 missing include of dma-direction.h 1 missing include of kthread.h 1 missing include of pagemap.h 1 missing include of string_helpers.h 1 missing include of writeback.h I tried to follow whatever conventions appeared to be in use for the various subsystems I touched; for example I added string_choices.h to drm_print.h instead of individually to each driver which used the functions declared there.

power: supply: bq27xxx: bq27z561: fix invalid AverageEnergy address

bq27z561 currently uses the AveragePower reg, 0x22, for reading both AveragePower and AvailableEnergy. The technical reference manual does not mention AvailableEnergy, and it does not make sense to read a cumulative, always positive, property like AvailableEnergy from a rate property like AveragePower.
