ASoC: Fixes for v6.19
A moderately large collection of fixes since I missed a week, plus a few
new device IDs and quirks. It's all fairly minor, including a bunch of
work on the device tree bindings fixes which have no runtime effect.
There's one SoundWire change here exporting a symbol which was required
for a fix to the ASoC SoundWire code.
Merge patches that Pengutronix have been carrying in their tree for a
while and were upstreamed by Sascha Hauer together with some new
features that are going into the next release.
Merge series from Richard Fitzgerald <rf@opensource.cirrus.com>:
This series fixes a problem with soc_sdw_utils.c calling the wrong
codec init callbacks, because it assumed that the DAI name could be
used to uniquely identify the codec. This isn't the case, especially
on SDCA which is a generic driver for many parts.
The first patch is needed to add a missing export to SoundWire core.
The word length is the physical width of the channel slots. So the
hw_params would misconfigure when format width and physical width
doesn't match. Like S24_LE which has data width of 24 bits but physical
width of 32 bits. So if using asymmetric formats you will get a lot of
noise.

When scanning for the reset pin, we could get an -EPROBE_DEFER.
The driver would assume that no reset pin had been defined,
which would mean that the chip would never be powered.
Now we both respect any error we get from devm_gpiod_get_optional.
We also now properly report the missing GPIO definition when
'gpio_reset' is NULL.

Looking at section 8.6.1.1.69 in datasheets for both 5140 and 6140 (3140
doesn't support DRE). REG ADCX140_DSP_CFG1 BIT 3 field "DRE_AGC_SEL" it
select either DRE or AGC.
It states:
* 0 = DRE
* 1 = AGC
The control is called "DRE_ENABLE" and for it to be true it has to be
active low.
This commit will invert the control so "DRE_ENABLE" is active low.

The CS42L43 codec's load detection can return different impedance values
that map to either HEADPHONE or LINEOUT jack types. However, the
soc_jack_pins array only maps SND_JACK_HEADPHONE to the "Headphone" DAPM
pin, not SND_JACK_LINEOUT.
When headphones are detected with an impedance that maps to LINEOUT
(such as impedance value 0x2), the driver reports SND_JACK_LINEOUT.
Since this doesn't match the jack pin mask, the "Headphone" DAPM pin
is not activated, and no audio is routed to the headphone outputs.
Fix by adding SND_JACK_LINEOUT to the Headphone pin mask, so that both
headphone and line-out detection properly enable the headphone output
path.
This fixes no audio output on devices like the Lenovo ThinkPad P16 Gen 3
where headphones are detected with LINEOUT impedance.

asoc_sdw_rtd_init() needs to call the rtd_init() callbacks for each
codec in a dailink. It was finding the codecs by looking for the
matching DAI name in codec_info_list[] but this isn't correct, because
the DAI name isn't guaranteed to be unique. Parts using the same codec
driver (so the same DAI names) might require different machine driver
setup.
Instead, get the struct sdw_slave and extract the SoundWire part ID.
Use this to lookup the entry in codec_info_list[]. This is the same
identity info that was used to find the entry when the machine driver
created the dailink.

Merge series from Jon Hunter <jonathanh@nvidia.com>:
This series includes fixes for the realtek,rt5640 dt-binding to address
a few warnings that are observed when running the CHECK_DTBS=y for some
DTBs that use this codec.
In this case, the user constructed the parameters with maxpacksize 40
for rate 22050 / pps 1000, and packsize[0] 22 packsize[1] 23. The buffer
size for each data URB is maxpacksize * packets, which in this example
is 40 * 6 = 240; When the user performs a write operation to send audio
data into the ALSA PCM playback stream, the calculated number of frames
is packsize[0] * packets = 264, which exceeds the allocated URB buffer
size, triggering the out-of-bounds (OOB) issue reported by syzbot [1].
Added a check for the number of single data URB frames when calculating
the number of frames to prevent [1].

The recent commit e5d527be7e ("gpio: swnode: don't use the
swnode's name as the key for GPIO lookup") broke cirrus_scodec_test,
because the software node no longer gets associated with the GPIO
driver by name.

will find the node using a normal fwnode lookup.

Just like GA403U, this GA403W needs to remap woofers to DAC1. Similarly to
other Asus devices, headphones/headset MIC is not working, however the pin
config alone is not enough to fix it.
From Windows dump of GA403W:
0x12, 0x90a60140 # Correctly set by codec out of the box
0x13, 0x90a60550
0x14, 0x90170510
0x17, 0x90170120 # Correctly set by codec out of the box
0x19, 0x03a11050 # Set by ALC285_FIXUP_ASUS_GA403U_HEADSET_MIC
0x1a, 0x411115F0
0x1b, 0x03a11c30 # Set by ALC285_FIXUP_ASUS_GA403U_HEADSET_MIC
0x1d, 0x40663A45 # Correctly set by codec out of the box
0x21, 0x03211430
Even with all the values set, MIC of the jack is not detected. Until a
complete solution is found, set ALC285_FIXUP_ASUS_GA403U_HEADSET_MIC
for GA403W which fixes audio volume control for woofers. No need to
create new quirk with missing pin config just yet, since its not
making the situation better.

Sheng Yong reported [1] that Android APEX images didn't work with commit
072a7c7cdb ("erofs: don't bother with s_stack_depth increasing for
now") because "EROFS-formatted APEX file images can be stored within an
EROFS-formatted Android system partition."
In response, I sent a quick fat-fingered [PATCH v3] to address the
report. Unfortunately, the updated condition was incorrect:
if (erofs_is_fileio_mode(sbi)) {
- sb->s_stack_depth =
- file_inode(sbi->dif0.file)->i_sb->s_stack_depth + 1;
- if (sb->s_stack_depth > FILESYSTEM_MAX_STACK_DEPTH) {
- erofs_err(sb, "maximum fs stacking depth exceeded");
+ inode = file_inode(sbi->dif0.file);
+ if ((inode->i_sb->s_op == &erofs_sops && !sb->s_bdev) ||
+ inode->i_sb->s_stack_depth) {
The condition `!sb->s_bdev` is always true for all file-backed EROFS
mounts, making the check effectively a no-op.
The real fix tested and confirmed by Sheng Yong [2] at that time was
[PATCH v3 RESEND], which correctly ensures the following EROFS^2 setup
works:
EROFS (on a block device) + EROFS (file-backed mount)
But sadly I screwed it up again by upstreaming the outdated [PATCH v3].
This patch applies the same logic as the delta between the upstream
[PATCH v3] and the real fix [PATCH v3 RESEND].

gcc 8.5 on powerpc does not automatically inline these functions even
though they evaluate to constants in key cases. Since the constant
propagation is essential for some code elimination and built-time checks
this causes a build failure:

Caused by this:
if (pts_feature(&pts, PT_FEAT_DMA_INCOHERENT) &&

Where pts_feature() evaluates to a constant false. Mark them as
__always_inline to force it to evaluate to a constant and trigger the code
elimination.

Pull erofs fix from Gao Xiang:
- Don't increase s_stack_depth which caused regressions in some
composefs mount setups (EROFS + ovl^2)
Instead just allow one extra unaccounted fs stacking level for
straightforward cases.
* tag 'erofs-for-6.19-rc5-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/xiang/erofs:
erofs: don't bother with s_stack_depth increasing for now
Previously, commit d53cd891f0 ("erofs: limit the level of fs stacking
for file-backed mounts") bumped `s_stack_depth` by one to avoid kernel
stack overflow when stacking an unlimited number of EROFS on top of
each other.
This fix breaks composefs mounts, which need EROFS+ovl^2 sometimes
(and such setups are already used in production for quite a long time).
One way to fix this regression is to bump FILESYSTEM_MAX_STACK_DEPTH
from 2 to 3, but proving that this is safe in general is a high bar.
After a long discussion on GitHub issues [1] about possible solutions,
one conclusion is that there is no need to support nesting file-backed
EROFS mounts on stacked filesystems, because there is always the option
to use loopback devices as a fallback.
As a quick fix for the composefs regression for this cycle, instead of
bumping `s_stack_depth` for file backed EROFS mounts, we disallow
nesting file-backed EROFS over EROFS and over filesystems with
`s_stack_depth` > 0.
This works for all known file-backed mount use cases (composefs,
containerd, and Android APEX for some Android vendors), and the fix is
self-contained.
Essentially, we are allowing one extra unaccounted fs stacking level of
EROFS below stacking filesystems, but EROFS can only be used in the read
path (i.e. overlayfs lower layers), which typically has much lower stack
usage than the write path.
We can consider increasing FILESYSTEM_MAX_STACK_DEPTH later, after more
stack usage analysis or using alternative approaches, such as splitting
the `s_stack_depth` limitation according to different combinations of
stacking.

Merge tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux
Pull arm64 fixes from Catalin Marinas:
- Do not return false if !preemptible() in current_in_efi(). EFI
runtime services can now run with preemption enabled
- Fix uninitialised variable in the arm MPAM driver, reported by sparse
- Fix partial kasan_reset_tag() use in change_memory_common() when
calculating page indices or comparing ranges
- Save/restore TCR2_EL1 during suspend/resume, otherwise the E0POE bit
is lost
* tag 'arm64-fixes' of git://git.kernel.org/pub/scm/linux/kernel/git/arm64/linux:
arm64: Fix cleared E0POE bit after cpu_suspend()/resume()
arm64: mm: Fix incomplete tag reset in change_memory_common()
arm_mpam: Stop using uninitialized variables in __ris_msmon_read()
arm64/efi: Don't fail check current_in_efi() if preemptible
The main code change is a revert of the Raspberry Pi RP1 overlay
support that was decided to not be ready.
The other fixes are all for devicetree sources:
- ethernet configuration on ixp42x-actiontec-mi424wr is
board revision specific
- validation warning fixes for imx27/imx51/imx6, hikey960 and k3
- Minor corrections across imx8 boards, addressing all types of
issues with interrups, dma, ethernet and clock settings, all
simple one-line changes.

When /sys/kernel/tracing/buffer_size_kb is less than 12KB,
the test_multiple_writes test will stall and wait for more
input due to insufficient buffer space.
Check current buffer_size_kb value before the test. If it is
less than 12KB, it temporarily increase the buffer to 12KB,
and restore the original value after the tests are completed.

Pull PCI fixes from Bjorn Helgaas:
- Remove ASPM L0s support for MSM8996 SoC since we now enable L0s when
advertised, and it caused random hangs on this device (Manivannan
Sadhasivam)
- Fix meson-pcie to report that the link is up while in ASPM L0s or L1,
since those are active states from the software point of view, and
treating the link as down caused config access failures (Bjorn
Helgaas)
- Fix up sparc DTS BAR descriptions that are above 4GB but not marked
as prefetchable, which caused resource assignment and driver probe
failures after we converted from the SPARC pcibios_enable_device() to
the generic version (Ilpo Järvinen)
