Merge tag 'pwrseq-updates-for-v7.3-rc1-part2' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

2026-08-26T15:45:09+00:00

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.

BackMerge tag 'v7.2' into drm-next

2026-08-20T00:58:44+00:00

Linux 7.2

There was a lot of conflicts this round between fixes and next,
and I'd like to get the merge resolutions that we have in drm-tip.

drm/imagination: Reuse layout check macros for MIPS FW structures

2026-08-03T10:25:42+00:00

Replace static asserts on MIPS firmware structures offsets and sizes
with more compact macros that are already used for similar checks on
common firmware interface structures.
