Pull perf tools updates from Arnaldo Carvalho de Melo:

- Use BPF + BTF to collect and pretty print syscall and tracepoint
arguments in 'perf trace', done as an GSoC activity

- Data-type profiling improvements:

- Cache debuginfo to speed up data type resolution

- Add the 'typecln' sort order, to show which cacheline in a target
is hot or cold. The following shows members in the cfs_rq's first
cache line:

$ perf report -s type,typecln,typeoff -H
...
- 2.67% struct cfs_rq
+ 1.23% struct cfs_rq: cache-line 2
+ 0.57% struct cfs_rq: cache-line 4
+ 0.46% struct cfs_rq: cache-line 6
- 0.41% struct cfs_rq: cache-line 0
0.39% struct cfs_rq +0x14 (h_nr_running)
0.02% struct cfs_rq +0x38 (tasks_timeline.rb_leftmost)

- When a typedef resolves to a unnamed struct, use the typedef name

- When a struct has just one basic type field (int, etc), resolve
the type sort order to the name of the struct, not the type of
the field

- Support type folding/unfolding in the data-type annotation TUI

- Fix bitfields offsets and sizes

- Initial support for PowerPC, using libcapstone and the usual
objdump disassembly parsing routines

- Add support for disassembling and addr2line using the LLVM libraries,
speeding up those operations

- Support --addr2line option in 'perf script' as with other tools

- Intel branch counters (LBR event logging) support, only available in
recent Intel processors, for instance, the new "brcntr" field can be
asked from 'perf script' to print the information collected from this
feature:

$ perf script -F +brstackinsn,+brcntr

# Branch counter abbr list:
# branch-instructions:ppp = A
# branch-misses = B
# '-' No event occurs
# '+' Event occurrences may be lost due to branch counter saturated

- Support Timed PEBS (Precise Event-Based Sampling), a recent hardware
feature in Intel processors

- Add 'perf ftrace profile' subcommand, using ftrace's function-graph
tracer so that users can see the total, average, max execution time
as well as the number of invocations easily, for instance:

$ sudo perf ftrace profile -G __x64_sys_perf_event_open -- \
perf stat -e cycles -C1 true 2> /dev/null | head

- 'perf sched timehist' improvements, including the addition of
priority showing/filtering command line options

- Varios improvements to the 'perf probe', including 'perf test'
regression testings

- Introduce the 'perf check', initially to check if some feature is
in place, using it in 'perf test'

- Various fixes for 32-bit systems

- Address more leak sanitizer failures

- Fix memory leaks (LBR, disasm lock ops, etc)

- More reference counting fixes (branch_info, etc)

- Constify 'struct perf_tool' parameters to improve code generation
and reduce the chances of having its internals changed, which isn't
expected

- More constifications in various other places

- Add more build tests, including for JEVENTS

- Add more 'perf test' entries ('perf record LBR', pipe/inject,
--setup-filter, 'perf ftrace', 'cgroup sampling', etc)

- Inject build ids for all entries in a call chain in 'perf inject',
not just for the main sample

- Improve the BPF based sample filter, allowing root to setup filters
in bpffs that then can be used by non-root users

- Allow filtering by cgroups with the BPF based sample filter

- Allow a more compact way for 'perf mem report' using the
-T/--type-profile and also provide a --sort option similar to the one
in 'perf report', 'perf top', to setup the sort order manually

- Fix --group behavior in 'perf annotate' when leader has no samples,
where it was not showing anything even when other events in the group
had samples

- Fix spinlock and rwlock accounting in 'perf lock contention'

- Fix libsubcmd fixdep Makefile dependencies

- Improve 'perf ftrace' error message when ftrace isn't available

- Update various Intel JSON vendor event files

- ARM64 CoreSight hardware tracing infrastructure improvements, mostly
not visible to users

- Update power10 JSON events

perf docs: Refine the description for the buffer size

Current description for the AUX trace buffer size is misleading. When a

Make the document clear that the normal buffer and the AUX tracing
buffer share the same semantics. Syncs the documents for consistent
text.

Merge series "Support ROHM BD71815 PMIC" from Matti Vaittinen <matti.vaittinen@fi.rohmeurope.com>:

Patch series introducing support for ROHM BD71815 PMIC

ROHM BD71815 is a power management IC used in some battery powered
systems. It contains regulators, GPO(s), charger + coulomb counter, RTC
and a clock gate.

All regulators can be controlled via I2C. LDO4 can additionally be set to
be enabled/disabled by a GPIO. LDO3 voltage could be selected from two
voltages written into separate VSEL reisters using GPIO but this mode is
not supported by driver. On top of that the PMIC has the typical HW
state machine which is present also on many other ROHM PMICs.

IC contains two GPOs - but one of the GPOs is marked as GND in
data-sheet. Thus the driver by default only exposes one GPO. The second
GPO can be enabled by special DT property.

RTC is almost similar to what is on BD71828. For currently used features
only the register address offset to RTC block differs.

The charger driver is not included in this series. ROHM has a charger
driver with some fuel-gauging logig written in but this is not included
here. I am working on separating the logic from HW specific driver and
supporting both BD71815 and BD71828 chargers in separate patch series.

Changelog v5:
Regulator:
- Added regmap helper for regulator ramp-delay and taken it in use
(patches 13, 14, 16 - they can be just dropped if ramp-delay helper is not
a good idea. Patch 15 implements old-fashioned ramp-delay)
GPIO:
- styling changes to GPIO (Mostly suggested by Andy)
- implemented init_valid_mask (but can't count on it yet)
Changelog v4:
- Sorted ROHM chip ID enum
- Statcized DVS structures in regulator driver
- Minor styling for regulator driver
- rebased on v5.12-rc4
Changelog v3:
- GPIO clean-up as suggested by Bartosz
- MFD clean-up as suggested by Lee
- clk-mode dt-binding handling in MFD driver corrected to reflect new
property values.
- Dropped already applied patches
- Rebased on v5.12-rc2
Changelog v2:
- Rebased on top of v5.11-rc3
- Added another "preliminary patch" which fixes HW-dvs voltage
handling (patch 1)
- split regulator patch to two.
- changed dt-binding patch ordering.
regulators:
- staticized probe
- removed some unnecessary defines
- updated comments
- split rohm-regulator patch adding SNVS and supporting simple
linear mapping into two - one adding support for mapping, other
adding SNVS.
GPIO:
- removed unnecessary headers
- clarified dev/parent->dev usage
- removed forgotten #define DEBUG
dt-bindings:
- changed patch order to meet ref-dependencies
- added missing regulator nodes
- changed string property for clk mode to tristated
MFD:
- header cleanups.
CLK:
- fixed commit message

Merge tag 'mute-led-rework' of https://git.kernel.org/pub/scm/linux/kernel/git/tiwai/sound into asoc-5.13

ALSA: control - add generic LED API

This patchset tries to resolve the diversity in the audio LED
control among the ALSA drivers. A new control layer registration
is introduced which allows to run additional operations on
top of the elementary ALSA sound controls.

A new control access group (three bits in the access flags)
was introduced to carry the LED group information for
the sound controls. The low-level sound drivers can just
mark those controls using this access group. This information
is not exported to the user space, but user space can
manage the LED sound control associations through sysfs
(last patch) per Mark's request. It makes things fully
configurable in the kernel and user space (UCM).

The actual state ('route') evaluation is really easy
(the minimal value check for all channels / controls / cards).
If there's more complicated logic for a given hardware,
the card driver may eventually export a new read-only
sound control for the LED group and do the logic itself.

The new LED trigger control code is completely separated
and possibly optional (there's no symbol dependency).
The full code separation allows eventually to move this
LED trigger control to the user space in future.
Actually it replaces the already present functionality
in the kernel space (HDA drivers) and allows a quick adoption
for the recent hardware (ASoC codecs including SoundWire).

snd_ctl_led 24576 0

The sound driver implementation is really easy:

1) call snd_ctl_led_request() when control LED layer should be
automatically activated
/ it calls module_request("snd-ctl-led") on demand /
2) mark all related kcontrols with
SNDRV_CTL_ELEM_ACCESS_SPK_LED or
SNDRV_CTL_ELEM_ACCESS_MIC_LED

- Fix event's PMU name parsing related to new drm/i915/gt
software-gt-awake-time event.

Fixes from compiler instrumentation:

- Fix leaks in 'perf test' entries, found using ASAN.

- Fix use-after-free when 'perf stat -r' option is used.

Arch specific:

- Fix bitmap for option om ARM's CS-ETM.

Documentation:

- Fix documentation of verbose options.

Build:

- Clean 'generated' directory used for creating the syscall table on
x86.

- Fix ccache usage in $(CC) when generating arch errno table.

- Cast (struct timeval).tv_sec when printing, fixing the build with
MUSL libc.
