Samsung fixes for v6.8
1. Google GS101: Correct the input clock names to CMU MISC clock
controller to match received review. The review was initially missed
and CMU MISC clock controller bindings, driver and DTS was merged
into v6.8-rc1 with different names. Nothing was released so far, so
the bindings and driver can be still corrected to match review.
2. Samsung Galaxy Tab3: Fix display by using correct vclk polarity in
display node.

Since commit 26c9d152ebf3 ("dt-bindings: tpm: Consolidate TCG TIS
bindings"), several issues are reported by "make dtbs_check" for ARM
devicetrees:
The nodename needs to be "tpm@0" rather than "tpmdev@0" and the
compatible property needs to contain the chip's name in addition to the
generic "tcg,tpm_tis-spi" or "tcg,tpm-tis-i2c":
tpmdev@0: $nodename:0: 'tpmdev@0' does not match '^tpm(@[0-9a-f]+)?$'
from schema $id: http://devicetree.org/schemas/tpm/tcg,tpm_tis-spi.yaml#
tpm@2e: compatible: 'oneOf' conditional failed, one must be fixed:
['tcg,tpm-tis-i2c'] is too short
from schema $id: http://devicetree.org/schemas/tpm/tcg,tpm-tis-i2c.yaml#
Fix these schema violations.
Aspeed Facebook BMCs use an Infineon SLB9670:

Aspeed Tacoma uses a Nuvoton NPCT75X per commit 39d8a73c53a2 ("ARM: dts:

https://lore.kernel.org/all/ab45c82485fa272f74adf560cbb58ee60cc42689.camel@phytec.de/
A single schema violation remains in am335x-moxa-uc-2100-common.dtsi
because it is unknown which chip is used on the board. The devicetree's
author has been asked for clarification but has not responded so far:

After more investigation, I've found that it's not the panel driver
config that needs to be modified to invert the data polarity, but
the FIMD config.
Add the missing invert-vclk option that is required to get the display
to work correctly.

gitolite.kernel.org:pub/scm/linux/kernel/git/vfs/vfs
Pull netfs updates from Christian Brauner:
"This extends the netfs helper library that network filesystems can use
to replace their own implementations. Both afs and 9p are ported. cifs
is ready as well but the patches are way bigger and will be routed
separately once this is merged. That will remove lots of code as well.
The overal goal is to get high-level I/O and knowledge of the page
cache and ouf of the filesystem drivers. This includes knowledge about
the existence of pages and folios
The pull request converts afs and 9p. This removes about 800 lines of
code from afs and 300 from 9p. For 9p it is now possible to do writes
in larger than a page chunks. Additionally, multipage folio support
can be turned on for 9p. Separate patches exist for cifs removing
another 2000+ lines. I've included detailed information in the
individual pulls I took.
Summary:
- Add NFS-style (and Ceph-style) locking around DIO vs buffered I/O
calls to prevent these from happening at the same time.
- Support for direct and unbuffered I/O.
- Support for write-through caching in the page cache.
- O_*SYNC and RWF_*SYNC writes use write-through rather than writing
to the page cache and then flushing afterwards.
- Support for write-streaming.
- Support for write grouping.
- Skip reads for which the server could only return zeros or EOF.
- The fscache module is now part of the netfs library and the
corresponding maintainer entry is updated.
- Some helpers from the fscache subsystem are renamed to mark them as
belonging to the netfs library.
- Follow-up fixes for the netfs library.
- Follow-up fixes for the 9p conversion"

"It was a calm development cycle. There were an ALSA core extension for
subformat PCM bits and a few ASoC core changes to support N:M

Core:
- API extensions for properly limiting PCM format bits via subformat
- Enhanced support for N:M CPU:CODEC mappings in the core and in
audio-graph-card2
ASoC:
- Lots of SOF updates: fallback support to older IPC versions,
notification on control changes with IPC4. Also supports for ACPI
parse for the ES83xx driver that reduces quirks.
- Device tree support for describing parts of the card which can be
active over suspend (for very low power playback or wake word use
cases)
- Support for more AMD and Intel systems, NXP i.MX8m MICFIL, Qualcomm
SM8250, SM8550, SM8650 and X1E80100
- Drop of Freescale MPC8610 code that is no longer supported

"There is one new SoC for each 32-bit Arm and 64-bit RISC-V, but both
the Rockchips rv1109 and Sopgho CV1812H are just minor variations of
already supported chips.
The other six new SoCs are all part of existing arm64 families, but
are somewhat more interesting:
- Samsung ExynosAutov920 is an automotive chip, and the first one we
support based on the Cortex-A78AE core with lockstep mode.
- Google gs101 (Tensor G1) is the chip used in a number of Pixel
phones, and is grouped with Samsung Exynos here since it is based
on the same SoC design, sharing most of its IP blocks with that
series.
- MediaTek MT8188 is a new chip used for mid-range tablets and
Chromebooks, using two Cortex-A78 cores where the older MT8195 had
four of them.
- Qualcomm SM8650 (Snapdragon 8 Gen 3) is their current top range
phone SoC and the first supported chip based on Cortex-X4,
Cortex-A720 and Cortex-A520.
- Qualcomm X1E80100 (Snapdragon X Elite) in turn is the latest Laptop
chip using the custom Oryon cores.
- Unisoc UMS9620 (Tanggula 7 series) is a 5G phone SoC based on
Cortex-A76 and Cortex-A55
In terms of boards, we have
- Five old Microsoft Lumia phones, the HTC One Mini 2, Motorola Moto
G 4G, and Huawei Honor 5X/GR5, all based on Snapdragon SoCs.
- Multiple Rockchips mobile gaming systems (Anbernic RG351V, Powkiddy
RK2023, Powkiddy X55) along with the Sonoff iHost Smart Home Hub
and a few Rockchips SBCs
- Some ComXpress boards based on Marvell CN913x, which is the
follow-up to Armada 7xxx/8xxx.
- Six new industrial/embedded boards based on NXP i.MX8 and i.MX9
- Mediatek MT8183 based Chromebooks from Lenovo, Asus and Acer.
- Toradex Verdin AM62 Mallow carrier for TI AM62
- Huashan Pi board based on the SophGo CV1812H RISC-V chip
- Two boards based on Allwinner H616/H618
- A number of reference boards for various added SoCs from Qualcomm,
Mediatek, Google, Samsung, NXP and Spreadtrum

git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm
Pull security module updates from Paul Moore:
- Add three new syscalls: lsm_list_modules(), lsm_get_self_attr(), and
lsm_set_self_attr().
The first syscall simply lists the LSMs enabled, while the second and
third get and set the current process' LSM attributes. Yes, these
syscalls may provide similar functionality to what can be found under
/proc or /sys, but they were designed to support multiple,
simultaneaous (stacked) LSMs from the start as opposed to the current
/proc based solutions which were created at a time when only one LSM
was allowed to be active at a given time.
We have spent considerable time discussing ways to extend the
existing /proc interfaces to support multiple, simultaneaous LSMs and
even our best ideas have been far too ugly to support as a kernel
API; after +20 years in the kernel, I felt the LSM layer had
established itself enough to justify a handful of syscalls.
Support amongst the individual LSM developers has been nearly
unanimous, with a single objection coming from Tetsuo (TOMOYO) as he
is worried that the LSM_ID_XXX token concept will make it more
difficult for out-of-tree LSMs to survive. Several members of the LSM
community have demonstrated the ability for out-of-tree LSMs to
continue to exist by picking high/unused LSM_ID values as well as
pointing out that many kernel APIs rely on integer identifiers, e.g.
syscalls (!), but unfortunately Tetsuo's objections remain.
My personal opinion is that while I have no interest in penalizing
out-of-tree LSMs, I'm not going to penalize in-tree development to
support out-of-tree development, and I view this as a necessary step
forward to support the push for expanded LSM stacking and reduce our
reliance on /proc and /sys which has occassionally been problematic
for some container users. Finally, we have included the linux-api
folks on (all?) recent revisions of the patchset and addressed all of
their concerns.
- Add a new security_file_ioctl_compat() LSM hook to handle the 32-bit
ioctls on 64-bit systems problem.
This patch includes support for all of the existing LSMs which
provide ioctl hooks, although it turns out only SELinux actually
cares about the individual ioctls. It is worth noting that while
Casey (Smack) and Tetsuo (TOMOYO) did not give explicit ACKs to this
patch, they did both indicate they are okay with the changes.
- Fix a potential memory leak in the CALIPSO code when IPv6 is disabled
at boot.
While it's good that we are fixing this, I doubt this is something
users are seeing in the wild as you need to both disable IPv6 and
then attempt to configure IPv6 labeled networking via
NetLabel/CALIPSO; that just doesn't make much sense.
Normally this would go through netdev, but Jakub asked me to take
this patch and of all the trees I maintain, the LSM tree seemed like
the best fit.
- Update the LSM MAINTAINERS entry with additional information about
our process docs, patchwork, bug reporting, etc.
I also noticed that the Lockdown LSM is missing a dedicated
MAINTAINERS entry so I've added that to the pull request. I've been
working with one of the major Lockdown authors/contributors to see if
they are willing to step up and assume a Lockdown maintainer role;
hopefully that will happen soon, but in the meantime I'll continue to
look after it.

Pull vfs mount updates from Christian Brauner:
"This contains the work to retrieve detailed information about mounts
via two new system calls. This is hopefully the beginning of the end
of the saga that started with fsinfo() years ago.
The LWN articles in [1] and [2] can serve as a summary so we can avoid
rehashing everything here.
At LSFMM in May 2022 we got into a room and agreed on what we want to
do about fsinfo(). Basically, split it into pieces. This is the first
part of that agreement. Specifically, it is concerned with retrieving
information about mounts. So this only concerns the mount information
retrieval, not the mount table change notification, or the extended
filesystem specific mount option work. That is separate work.
Currently mounts have a 32bit id. Mount ids are already in heavy use
by libmount and other low-level userspace but they can't be relied
upon because they're recycled very quickly. We agreed that mounts
should carry a unique 64bit id by which they can be referenced
directly. This is now implemented as part of this work.
The new 64bit mount id is exposed in statx() through the new
STATX_MNT_ID_UNIQUE flag. If the flag isn't raised the old mount id is
returned. If it is raised and the kernel supports the new 64bit mount
id the flag is raised in the result mask and the new 64bit mount id is
returned. New and old mount ids do not overlap so they cannot be
conflated.
Two new system calls are introduced that operate on the 64bit mount
id: statmount() and listmount(). A summary of the api and usage can be
found on LWN as well (cf. [3]) but of course, I'll provide a summary
here as well.
Both system calls rely on struct mnt_id_req. Which is the request
struct used to pass the 64bit mount id identifying the mount to
operate on. It is extensible to allow for the addition of new
parameters and for future use in other apis that make use of mount
ids.
statmount() mimicks the semantics of statx() and exposes a set flags
that userspace may raise in mnt_id_req to request specific information
to be retrieved. A statmount() call returns a struct statmount filled
in with information about the requested mount. Supported requests are
indicated by raising the request flag passed in struct mnt_id_req in
the @mask argument in struct statmount.
Currently we do support:
- STATMOUNT_SB_BASIC:
Basic filesystem info
- STATMOUNT_MNT_BASIC
Mount information (mount id, parent mount id, mount attributes etc)
- STATMOUNT_PROPAGATE_FROM
Propagation from what mount in current namespace
- STATMOUNT_MNT_ROOT
Path of the root of the mount (e.g., mount --bind /bla /mnt returns /bla)
- STATMOUNT_MNT_POINT
Path of the mount point (e.g., mount --bind /bla /mnt returns /mnt)
- STATMOUNT_FS_TYPE
Name of the filesystem type as the magic number isn't enough due to submounts
The string options STATMOUNT_MNT_{ROOT,POINT} and STATMOUNT_FS_TYPE
are appended to the end of the struct. Userspace can use the offsets
in @fs_type, @mnt_root, and @mnt_point to reference those strings
easily.
The struct statmount reserves quite a bit of space currently for
future extensibility. This isn't really a problem and if this bothers
us we can just send a follow-up pull request during this cycle.
listmount() is given a 64bit mount id via mnt_id_req just as
statmount(). It takes a buffer and a size to return an array of the
64bit ids of the child mounts of the requested mount. Userspace can
thus choose to either retrieve child mounts for a mount in batches or
iterate through the child mounts. For most use-cases it will be
sufficient to just leave space for a few child mounts. But for big
mount tables having an iterator is really helpful. Iterating through a
mount table works by setting @param in mnt_id_req to the mount id of
the last child mount retrieved in the previous listmount() call"

Now that the driver core can properly handle constant struct bus_type,
move the locomo_bus_type variable to be a constant structure as well,
placing it into read-only memory which can not be modified at runtime.
It's also never used outside of arch/arm/common/locomo.c so make it
static and don't export it as no one is using it.

of_property_match_string returns an int; either an index from 0 or
greater if successful or negative on failure. Even it's very
unlikely that the DT CPU node contains multiple enable-methods
these checks should be fixed.
This patch was inspired by the work of Nick Desaulniers.

Running a multi-arch kernel (multi_v7_defconfig) on a Raspberry Pi 3B+

Since the enabled method couldn't match with any entry from
sunxi_mc_smp_data, the value of the index shouldn't be used right after
the loop. So move it after the check of ret in order to have a valid
index.

A few more Qualcomm Arm32 DeviceTree updates fr v6.8
The recently introduced changes to the SDX55 USB controller interrupt
flags prevents the USB controller from probing. These patches corrects
the PDC's interrupt-cells, so that appropriate interrupt controller
(which supports both-edge interrupts) can be used instead, which
resolves the issue.
The SDX55 PCIe PHY base address is also adjusted, from a mistake when
the node recently was transitioned to the modernized DeviceTree binding.

This should be a per board property, should not be put in
a soc core dtsi.
And when this property convert from default-sample-phase
in linux-5.7 by commit 8a385eb57296 ("ARM: dts: rockchip: fix
rockchip,default-sample-phase property names"), the emmc
on rk3036 kylin board get a initialising error:
[ 4.512797] Freeing unused kernel memory: 8192K
[ 4.519500] mmc_host mmc1: Bus speed (slot 0) = 37125000Hz (slot req 37500000Hz, actual 37125000HZ div = 0)
[ 4.530971] mmc1: error -84 whilst initialising MMC card

[ 4.676156] mmc1: error -84 whilst initialising MMC card
I think the reason why the emmc on rk3036 kylin board was able
to work before linux-5.7 was that the illegal property was not
correctly identified by the rockchip dw_mmc driver.

Create a new method to get a unique and fixed max frequency. Currently
cpuinfo.max_freq or the highest (or last) state of performance domain are
used as the max frequency when computing the frequency for a level of
utilization, but:
- cpuinfo_max_freq can change at runtime. boost is one example of
such change.
- cpuinfo.max_freq and last item of the PD can be different leading to
different results between cpufreq and energy model.
We need to save the reference frequency that has been used when computing
the CPUs capacity and use this fixed and coherent value to convert between
frequency and CPU's capacity.
In fact, we already save the frequency that has been used when computing
the capacity of each CPU. We extend the precision to save kHz instead of
MHz currently and we modify the type to be aligned with other variables
used when converting frequency to capacity and the other way.
