Pull sound fixes from Takashi Iwai: "The regular "bump-in-the-middle" updates, containing mostly ASoC- related fixes at this time. All changes are reasonably small. A few entries are for ASoC and ALSA core parts (DAPM, PCM, topology) for followups of the recent changes and potential buffer overflow by snprintf(), while the rest are (both new and old) device-specific fixes for Intel, meson, tas2562, rt1015, as well as the usual HD-audio quirks" * tag 'sound-5.6-rc5' of git://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound: (25 commits) ALSA: sgio2audio: Remove usage of dropped hw_params/hw_free functions ALSA: hda/realtek - Enable the headset of ASUS B9450FA with ALC294 ALSA: hda/realtek - Fix silent output on Gigabyte X570 Aorus Master ALSA: hda/realtek - Add Headset Button supported for ThinkPad X1 ALSA: hda/realtek - Add Headset Mic supported ASoC: wm8741: Fix typo in Kconfig prompt ASoC: stm32: sai: manage rebind issue ASoC: SOF: Fix snd_sof_ipc_stream_posn() ASoC: rt1015: modify pre-divider for sysclk ASoC: rt1015: add operation callback function for rt1015_dai[] ASoC: soc-component: tidyup snd_soc_pcm_component_sync_stop() ASoC: dapm: Correct DAPM handling of active widgets during shutdown ASoC: tas2562: Fix sample rate error message ASoC: Intel: Skylake: Fix available clock counter incrementation ASoC: soc-pcm/soc-compress: don't use snd_soc_dapm_stream_stop() ASoC: meson: g12a: add tohdmitx reset ASoC: pcm512x: Fix unbalanced regulator enable call in probe error path ASoC: soc-core: fix for_rtd_codec_dai_rollback() macro ASoC: topology: Fix memleak in soc_tplg_manifest_load() ASoC: topology: Fix memleak in soc_tplg_link_elems_load() ...

bool "Generic Dynamic Voltage and Frequency Scaling (DVFS) support"
select SRCU
select PM_OPP
help
A device may have a list of frequencies and voltages available.
devfreq, a generic DVFS framework can be registered for a device
in order to let the governor provided to devfreq choose an
operating frequency based on the device driver's policy.
Each device may have its own governor and policy. Devfreq can
reevaluate the device state periodically and/or based on the
notification to "nb", a notifier block, of devfreq.
Like some CPUs with CPUfreq, a device may have multiple clocks.
However, because the clock frequencies of a single device are
determined by the single device's state, an instance of devfreq
is attached to a single device and returns a "representative"
clock frequency of the device, which is also attached
to a device by 1-to-1. The device registering devfreq takes the
responsibility to "interpret" the representative frequency and
to set its every clock accordingly with the "target" callback
given to devfreq.
When OPP is used with the devfreq device, it is recommended to
register devfreq's nb to the OPP's notifier head. If OPP is
used with the devfreq device, you may use OPP helper
functions defined in devfreq.h.

comment "DEVFREQ Governors"
config DEVFREQ_GOV_SIMPLE_ONDEMAND
tristate "Simple Ondemand"
help
Chooses frequency based on the recent load on the device. Works
similar as ONDEMAND governor of CPUFREQ does. A device with
Simple-Ondemand should be able to provide busy/total counter
values that imply the usage rate. A device may provide tuned
values to the governor with data field at devfreq_add_device().
config DEVFREQ_GOV_PERFORMANCE
tristate "Performance"
help
Sets the frequency at the maximum available frequency.
This governor always returns UINT_MAX as frequency so that
the DEVFREQ framework returns the highest frequency available
at any time.
config DEVFREQ_GOV_POWERSAVE
tristate "Powersave"
help
Sets the frequency at the minimum available frequency.
This governor always returns 0 as frequency so that
the DEVFREQ framework returns the lowest frequency available
at any time.
config DEVFREQ_GOV_USERSPACE
tristate "Userspace"
help
Sets the frequency at the user specified one.
This governor returns the user configured frequency if there
has been an input to /sys/devices/.../power/devfreq_set_freq.
Otherwise, the governor does not change the frequency
given at the initialization.
config DEVFREQ_GOV_PASSIVE
tristate "Passive"
help
Sets the frequency based on the frequency of its parent devfreq
device. This governor does not change the frequency by itself
through sysfs entries. The passive governor recommends that
devfreq device uses the OPP table to get the frequency/voltage.

help
This adds the common DEVFREQ driver for Exynos Memory bus. Exynos
Memory bus has one more group of memory bus (e.g, MIF and INT block).
Each memory bus group could contain many memoby bus block. It reads
PPMU counters of memory controllers by using DEVFREQ-event device
and adjusts the operating frequencies and voltages with OPP support.
This does not yet operate with optimal voltages.
