Subject: [GIT PULL] More power management updates for v6.9-rc1

Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.9-rc1-2

with top-most commit a6d6590917ec352270bd3e3c040240aab31f2e90

 Merge branches 'pm-em', 'pm-powercap' and 'pm-sleep'

on top of commit 07abb19a9b201c11e4367e8a428be7235b6dbd0d

 Merge tag 'pm-6.9-rc1' of
git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

to receive more power management updates for 6.9-rc1.

These update the Energy Model to make it prevent errors due to power
unit mismatches, fix a typo in power management documentation,
convert one driver to using a platform remove callback returning void,
address two cpufreq issues (one in the core and one in the DT driver),
and enable boost support in the SCMI cpufreq driver.

Specifics:

 - Modify the Energy Model code to bail out and complain if the unit of
   power is not uW to prevent errors due to unit mismatches (Lukasz Luba).

 - Make the intel_rapl platform driver use a remove callback returning
   void (Uwe Kleine-König).

 - Fix typo in the suspend and interrupts document (Saravana Kannan).

 - Make per-policy boost flags actually take effect on platforms using
   cpufreq_boost_set_sw() (Sibi Sankar).

 - Enable boost support in the SCMI cpufreq driver (Sibi Sankar).

 - Make the DT cpufreq driver use zalloc_cpumask_var() for allocating
   cpumasks to avoid using uninitialized memory (Marek Szyprowski).

Thanks!
