Pull power management fixes from Rafael Wysocki: "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)" * tag 'pm-6.7-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm: cpufreq/amd-pstate: Only print supported EPP values for performance governor cpufreq/amd-pstate: Fix scaling_min_freq and scaling_max_freq update powercap: DTPM: Fix unneeded conversions to micro-Watts cpufreq/amd-pstate: Fix the return value of amd_pstate_fast_switch() pmdomain: qcom: rpmpd: Set GENPD_FLAG_ACTIVE_WAKEUP cpufreq: qcom-nvmem: Preserve PM domain votes in system suspend cpufreq: qcom-nvmem: Enable virtual power domain devices cpufreq: imx6q: Don't disable 792 Mhz OPP unnecessarily

help
Use the power-on LED on your machine as a load meter. The exact
behavior is platform-dependent, but normally the flash frequency is
a hyperbolic function of the 5-minute load average.
# We have a dedicated heartbeat LED. :-)
config PROC_HARDWARE
bool "/proc/hardware support"
depends on PROC_FS
help
Say Y here to support the /proc/hardware file, which gives you
access to information about the machine you're running on,
including the model, CPU, MMU, clock speed, BogoMIPS rating,
and memory size.
config NATFEAT
bool "ARAnyM emulator support"
depends on ATARI
help
This option enables support for ARAnyM native features, such as
access to a disk image as /dev/hda.
config NFBLOCK
tristate "NatFeat block device support"
depends on BLOCK && NATFEAT
help
Say Y to include support for the ARAnyM NatFeat block device
which allows direct access to the hard drives without using
the hardware emulation.
config NFCON
tristate "NatFeat console driver"
depends on TTY && NATFEAT
help
Say Y to include support for the ARAnyM NatFeat console driver
which allows the console output to be redirected to the stderr
output of ARAnyM.
config NFETH
tristate "NatFeat Ethernet support"
depends on ETHERNET && NATFEAT
help
Say Y to include support for the ARAnyM NatFeat network device
which will emulate a regular ethernet device while presenting an
ethertap device to the host system.
config ATARI_ETHERNAT
bool "Atari EtherNAT Ethernet support"
depends on ATARI
help
Say Y to include support for the EtherNAT network adapter for the
CT/60 extension port.
To compile the actual ethernet driver, choose Y or M for the SMC91X
option in the network device section; the module will be called smc91x.
config ATARI_ETHERNEC
bool "Atari EtherNEC Ethernet support"
depends on ATARI_ROM_ISA
help
Say Y to include support for the EtherNEC network adapter for the
ROM port. The driver works by polling instead of interrupts, so it
is quite slow.
This driver also supports the ethernet part of the NetUSBee ROM
port combined Ethernet/USB adapter.
To compile the actual ethernet driver, choose Y or M in for the NE2000
option in the network device section; the module will be called ne.

config ATARI_DSP56K
tristate "Atari DSP56k support"

help
If you want to be able to use the DSP56001 in Falcons, say Y. This
driver is still experimental, and if you don't know what it is, or
if you don't have this processor, just say N.
To compile this driver as a module, choose M here.
config AMIGA_BUILTIN_SERIAL
tristate "Amiga builtin serial support"
depends on AMIGA && TTY
help
If you want to use your Amiga's built-in serial port in Linux,
answer Y.
To compile this driver as a module, choose M here.

tristate "HP DCA serial support"

help
If you want to use the internal "DCA" serial ports on an HP300
machine, say Y here.
config HPAPCI
tristate "HP APCI serial support"
depends on HP300 && SERIAL_8250
help
If you want to use the internal "APCI" serial ports on an HP400
machine, say Y here.
config SERIAL_CONSOLE
bool "Support for serial port console"
depends on AMIGA_BUILTIN_SERIAL=y
help
If you say Y here, it will be possible to use a serial port as the
system console (the system console is the device which receives all
kernel messages and warnings and which allows logins in single user
mode). This could be useful if some terminal or printer is connected
to that serial port.
Even if you say Y here, the currently visible virtual console
(/dev/tty0) will still be used as the system console by default, but
you can alter that using a kernel command line option such as
"console=ttyS1". (Try "man bootparam" or see the documentation of
your boot loader about how to pass options to the kernel at boot
time.)
If you don't have a graphical console and you say Y here, the
kernel will automatically use the first serial line, /dev/ttyS0, as
system console.
If unsure, say N.
