The Asus USB DAC is a USB type-C audio dongle for connecting to
the headset and headphone. The volume minimum value -23040 which
is 0xa600 in hexadecimal with the resolution value 1 indicates
this should be endianness issue caused by the firmware bug. Add
a volume quirk to fix the volume control problem.
Also fixes this warning:
Warning! Unlikely big volume range (=23040), cval->res is probably wrong.
[5] FU [Headset Capture Volume] ch = 1, val = -23040/0/1

We fixed the regression of the speaker volume for some Thinkpad models
(e.g. T570) by the commit 54947cd64c ("ALSA: hda/realtek - Fix
speaker output regression on Thinkpad T570"). Essentially it fixes
the DAC / pin pairing by a static table. It was confirmed and merged
to stable kernel later.
Now, interestingly, we got another regression report for the very same
model (T570) about the similar problem, and the commit above was the
culprit. That is, by some reason, there are devices that prefer the
DAC1, and another device DAC2!
Unfortunately those have the same ID and we have no idea what can
differentiate, in this patch, a new fixup model "tpt470-dock-fix" is
provided, so that users with such a machine can apply it manually.
When model=tpt470-dock-fix option is passed to snd-hda-intel module,
it avoids the fixed DAC pairing and the DAC1 is assigned to the
speaker like the earlier versions.

Hi Mark
Current ALSA SoC is handling dai_link related operation,
but it is implmemented directly without using function/macro,
and at random place.
This v4 patch-set creates new snd_soc_link_xxx() functions
which handles dai_link related operation,
and implmement these at new soc-link.c.
v3 -> v4
- add Reviewed-by from Ranjani and Pierre-Louis
- fix bisection error at [2/7]
v2 -> v3
- add missing #include <sound/soc-link.h> in soc-link.c
v1 -> v2
- #include <sound/soc-link.h> is added on each c source file
instead of soc.h
- not have extra error message after snd_soc_link_xxx(),
because it already indicate it via snc_link_ret()
- snd_soc_link_compr_xxx() doesn't have rtd parameter,
because it can be created from cstream

Hello,
extended firmware manifest is a method to retrieve capabilities
directly from the firmware file instead of routing the information via
the DSP and reading it back via IPC (latter mechanism still supported
but will be deprecated).
This feature was briefly merged to 5.8 with the series sent on
2020-Apr-15, but due to a regression hit with exporting uapi headers,
the patches got dropped.
Here's an update with the uapi header issue fixed, rebased to latest
'for-5.8' and a few minor fixes. This has been sitting in sof-dev for
some weeks and no further issues have been found. We also added
a check for the uapi-export case to SOF CI, so such errors would
not slip through again in the future.
Tooling support to create firmware files with an extended header
is available in SOF firmware repository (see the rimage tool) and
this part is already merged.

With dedicated power domain for asrc, power can be disabled after
probe and pm runtime suspend, then the value of all registers need to
be restored in pm runtime resume. So we can merge suspend/resume function
to runtime_suspend/resume function and enable regcache only in end of
probe.

vlan_for_each() are required to be called with rtnl_lock taken, otherwise
ASSERT_RTNL() warning will be triggered - which happens now during System
resume from suspend:
cpsw_suspend()
|- cpsw_ndo_stop()
|- __hw_addr_ref_unsync_dev()
|- cpsw_purge_all_mc()
|- vlan_for_each()
|- ASSERT_RTNL();
Hence, fix it by surrounding cpsw_ndo_stop() by rtnl_lock/unlock() calls.

At the very end of the MACsec block initialization in the MSCC PHY
driver, the MACsec "protocol mode" is set. This setting should be set
based on the PHY id within the package, as the bank used to access the
register used depends on this. This was not done correctly, and only the
first bank was used leading to the two upper PHYs being unstable when
using the VSC8584. This patch fixes it.

Commit 14b41a2959 ("net: stmmac: Delete txtimer in suspend") was the
first attempt to fix a race between mod_timer() and setup_timer()
during stmmac_resume(). However the issue still exists as the commit
only addressed half of the issue.
Same race can still happen as stmmac_resume() re-attaches interface
way too early - even before hardware is fully initialized. Worse,
doing so allows network traffic to restart and stmmac_tx_timer_arm()
being called in the middle of stmmac_resume(), which re-init tx timers
in stmmac_init_coalesce(). timer_list will be corrupted and system
crashes as a result of race between mod_timer() and setup_timer().

The srmmu_nocache_init() uses __nocache_fix() macro to add an offset to
page table entry to access srmmu_nocache_pool.
But since sparc32 has only three actual page table levels, pgd, p4d and
pud are essentially the same thing and pgd_offset() and p4d_offset() are
no-ops, the __nocache_fix() should be done only at PUD level.
Remove __nocache_fix() for p4d_offset() and pud_offset() and keep it
only for PUD and lower levels.

300 | pud_t *pud;
This warning is caused by misprint in the page table traversal in
srmmu_nocache_init() function which accessed a PMD entry using PGD
rather than PUD.
Since sparc32 has only 3 page table levels, the PGD and PUD are
essentially the same and usage of __nocache_fix() removed the type
checking.
Use PUD for the consistency and to silence the compiler warning.

During early boot, while KASAN is not yet initialized, it is possible to
enter reporting code-path and end up in kasan_report().
While uninitialized, the branch there prevents generating any reports,
however, under certain circumstances when branches are being traced
(TRACE_BRANCH_PROFILING), we may recurse deep enough to cause kernel
reboots without warning.
To prevent similar issues in future, we should disable branch tracing
for the core runtime.
