Merge tag 'asoc-v6.9' of https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound into for-linus

ASoC: Updates for v6.9

This has been quite a small release, there's a lot of driver specific
cleanups and minor enhancements but hardly anything on the core and only
one new driver. Highlights include:

- SoundWire support for AMD ACP 6.3 systems.
- Support for reporting version information for AVS firmware.
- Support DSPless mode for Intel Soundwire systems.
- Support for configuring CS35L56 amplifiers using EFI calibration
data.
- Log which component is being operated on as part of power management
trace events.
- Support for Microchip SAM9x7, NXP i.MX95 and Qualcomm WCD939x

ASoC: Intel: avs: Fixes and new platforms support

Merge series from Cezary Rojewski <cezary.rojewski@intel.com>:

The avs-driver continues to be utilized on more recent Intel machines.
As TGL-based (cAVS 2.5) e.g.: RPL, inherit most of the functionality
from previous platforms:

SKL <- APL <- CNL <- ICL <- TGL

rather than putting everything into a single file, the platform-specific
bits are split into cnl/icl/tgl.c files instead. Makes the division clear
and code easier to maintain.

Layout of the patchset:

First are two changes combined together address the sound-clipping
problem, present when only one stream is running - specifically one
CAPTURE stream.

Follow up is naming-scheme adjustment for some of the existing functions
what improves code incohesiveness. As existing IPC/IRQ code operates
solely on cAVS 1.5 architecture, it needs no abstraction. The situation
changes when newer platforms come into the picture. Thus the next two
patches abstract the existing IPC/IRQ handlers so that majority of the
common code can be re-used.

The ICCMAX change stands out a bit - the AudioDSP firmware loading
procedure differs on ICL-based platforms (and onwards) and having a
separate commit makes the situation clear to the developers who are
going to support the solution from LTS perspective. For that reason
I decided not to merge it into the commit introducing the icl.c file.

Merge tag 'trace-v6.8-rc2' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace

Pull tracing and eventfs fixes from Steven Rostedt:

- Fix the return code for ring_buffer_poll_wait()

It was returing a -EINVAL instead of EPOLLERR.

- Zero out the tracefs_inode so that all fields are initialized.

The ti->private could have had stale data, but instead of just
initializing it to NULL, clear out the entire structure when it is
allocated.

- Fix a crash in timerlat

The hrtimer was initialized at read and not open, but is canceled at
close. If the file was opened and never read the close will pass a
NULL pointer to hrtime_cancel().

- Rewrite of eventfs.

Linus wrote a patch series to remove the dentry references in the
eventfs_inode and to use ref counting and more of proper VFS
interfaces to make it work.

- Add warning to put_ei() if ei is not set to free. That means
something is about to free it when it shouldn't.

- Restructure the eventfs_inode to make it more compact, and remove the
unused llist field.

- Remove the fsnotify*() funtions for when the inodes were being
created in the lookup code. It doesn't make sense to notify about
creation just because something is being looked up.

- The inode hard link count was not accurate.

It was being updated when a file was looked up. The inodes of
directories were updating their parent inode hard link count every
time the inode was created. That means if memory reclaim cleaned a
stale directory inode and the inode was lookup up again, it would
increment the parent inode again as well. Al Viro said to just have
all eventfs directories have a hard link count of 1. That tells user
space not to trust it.

tracing/timerlat: Move hrtimer_init to timerlat_fd open()

Currently, the timerlat's hrtimer is initialized at the first read of
timerlat_fd, and destroyed at close(). It works, but it causes an error
if the user program open() and close() the file without reading.

Here's an example:

# echo NO_OSNOISE_WORKLOAD > /sys/kernel/debug/tracing/osnoise/options
# echo timerlat > /sys/kernel/debug/tracing/current_tracer

# cat <<EOF > ./timerlat_load.py
# !/usr/bin/env python3

timerlat_fd = open("/sys/kernel/tracing/osnoise/per_cpu/cpu0/timerlat_fd", 'r')
timerlat_fd.close();
