Subject: [GIT PULL] Power management fixes for v6.7-rc4

 Hi Linus,

Please pull from the tag

 git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm.git \
 pm-6.7-rc4

with top-most commit a6b31256928d78204f8f282220d3b0d64387f79d

 Merge branch 'powercap'

on top of commit 2cc14f52aeb78ce3f29677c2de1f06c0e91471ab

 Linux 6.7-rc3

to receive power management fixes for 6.7-rc4.

These fix issues in two cpufreq drivers, in the AMD P-state driver and
in the power-capping DTPM framework.

Specifics:

 - Fix the AMD P-state driver's EPP sysfs interface in the cases when the
   performance governor is in use (Ayush Jain).

 - Make the ->fast_switch() callback in the AMD P-state driver return the
   target frequency as expected (Gautham R. Shenoy).

 - Allow user space to control the range of frequencies to use via
   scaling_min_freq and scaling_max_freq when AMD P-state driver is in
   use (Wyes Karny).

 - Prevent power domains needed for wakeup signaling from being turned
   off during system suspend on Qualcomm systems and prevent performance
   states votes from runtime-suspended devices from being lost across
   a system suspend-resume cycle in qcom-cpufreq-nvmem (Stephan Gerhold).

 - Fix disabling the 792 Mhz OPP in the imx6q cpufreq driver for the
   i.MX6ULL types that can run at that frequency (Christoph Niedermaier).

 - Eliminate unnecessary and harmful conversions to uW from the DTPM
   (dynamic thermal and power management) framework (Lukasz Luba).

Thanks!
