commit 379c590113ce46f605439d4887996c60ab8820cc upstream.
When the addresses of the shmobile_smp_mpidr, shmobile_smp_fn, and
shmobile_smp_arg variables are not multiples of 4 bytes, secondary CPU
bring-up fails:
smp: Bringing up secondary CPUs ...
CPU1: failed to come online
CPU2: failed to come online
CPU3: failed to come online
smp: Brought up 1 node, 1 CPU
Fix this by adding the missing alignment directive.

commit 83964a29379cb08929a39172780a4c2992bc7c93 upstream.
The current solution for powering off the Apalis iMX6 is not functioning
as intended. To resolve this, it is necessary to power off the
vgen2_reg, which will also set the POWER_ENABLE_MOCI signal to a low
state. This ensures the carrier board is properly informed to initiate
its power-off sequence.
The new solution uses the regulator-poweroff driver, which will power
off the regulator during a system shutdown.

[ Upstream commit c24f272ae751a9f54f8816430e7f2d56031892cc ]
During upstream process of Raspberry Pi 4 back in 2019 the ARMv7 stubs
didn't configured the ARM architectural timer. This firmware issue has
been fixed in 2020, which gave users enough time to update their system.
So drop this property to allow the use of the vDSO version of
clock_gettime.

[ Upstream commit f44fa354a0715577ca32b085f6f60bcf32c748dd ]
During s2idle tests on the Raspberry CM4 the VPU firmware always crashes
on xHCI power-domain resume:
root@raspberrypi:/sys/power# echo freeze > state
[ 70.724347] xhci_suspend finished
[ 70.727730] xhci_plat_suspend finished

[ 70.761127] USB: Set power to 0
[ 74.653040] USB: Failed to set power to 1 (-110)
This seems to be caused because of the mixed usage of
raspberrypi-power and bcm2835-power at the same time. So avoid
the usage of the VPU firmware power-domain driver, which
prevents the VPU crash.

commit a564ccfe300fa6a065beda06ab7f3c140d6b4d63 upstream.

To fix it, do not rely on whether 'ptl' is equal to decide whether to hold
the pte lock, but decide it by whether CONFIG_SPLIT_PTE_PTLOCKS is
enabled. In addition, if two vmas map to the same PTE page, there is no
need to hold the pte lock again, otherwise a deadlock will occur. Just
add the need_lock parameter to let adjust_pte() know this information.

commit 0cfbd7805fe13406500e6a6f2aa08f198d5db4bd upstream.
Despite CM_IDLEST1_CORE and CM_FCLKEN1_CORE behaving normal,
disabling SPI leads to messages like when suspending:
Powerdomain (core_pwrdm) didn't enter target state 0
and according to /sys/kernel/debug/pm_debug/count off state is not
entered. That was not connected to SPI during the discussion
of disabling SPI. See:
https://lore.kernel.org/linux-omap/20230122100852.32ae082c@aktux/
The reason is that SPI is per default in slave mode. Linux driver
will turn it to master per default. It slave mode, the powerdomain seems to
be kept active if active chip select input is sensed.
Fix that by explicitly disabling the SPI3 pins which used to be muxed by
the bootloader since they are available on an optionally fitted header
which would require dtb overlays anyways.

commit c1472ec1dc4419d0bae663c1a1e6cb98dc7881ad upstream.
A bus_dma_limit was added for l3 bus by commit cfb5d65f2595
("ARM: dts: dra7: Add bus_dma_limit for L3 bus") to fix an issue
observed only with SATA on DRA7-EVM with 4GB RAM and CONFIG_ARM_LPAE
enabled.
Since kernel 5.13, the SATA issue can be reproduced again following
the SATA node move from L3 bus to L4_cfg in commit 8af15365a368
("ARM: dts: Configure interconnect target module for dra7 sata").
Fix it by adding an empty dma-ranges property to l4_cfg and
segment@100000 nodes (parent device tree node of SATA controller) to
inherit the 2GB dma ranges limit from l3 bus node.
Note: A similar fix was applied for PCIe controller by commit
90d4d3f4ea45 ("ARM: dts: dra7: Fix bus_dma_limit for PCIe").
Fixes: 8af15365a368 ("ARM: dts: Configure interconnect target module for dra7 sata").

[ Upstream commit 4ea654242e0c75bdf6b45d3c619c5fdcb2e9312a ]
The GIC IRQ type used for IPCC RX should be IRQ_TYPE_LEVEL_HIGH.
Replacing the interrupt with the EXTI event changes the type to
the numeric value 1, meaning IRQ_TYPE_EDGE_RISING.
The issue is that EXTI event 61 is a direct event.The IRQ type of
direct events is not used by EXTI and is propagated to the parent
IRQ controller of EXTI, the GIC.
Align the IRQ type to the value expected by the GIC by replacing
the second parameter "1" with IRQ_TYPE_LEVEL_HIGH.

[ Upstream commit 6fc5bdfa872b7da51b5507a1327a17c3db2fcf95 ]
Change how the Backup Unit Power is configured and force the
automatic/hardware mode.
This change eliminates the need for software management of the power
switch, ensuring it transitions to the backup power source before
entering low power modes.
This is done in the only location where this switch was configured. It's
usually done in the bootloader.
Previously, the loss of the VDDANA (or VDDIN33) power source was not
automatically compensated by an alternative power source. This resulted
in the loss of Backup Unit content, including Backup Self-refresh low
power mode information, OTP emulation configuration, and boot
configuration, for instance.

Enable SND_SOC_SPDIF in imx_v6_v7_defconfig to support SPDIF audio.
With commit d469b771afe1 ("ARM: dts: imx6: update spdif sound card node
properties"), the more generic audio-codec property is used instead of
the old spdif-controller property. Since most i.MX6 boards now use the
audio-codec property together with the linux,spdif-dit and
linux,spdif-dir compatible driver, it makes sense to enable
SND_SOC_SPDIF in the imx_v6_v7_defconfig. This will ensure compatibility
with the updated device tree.
Without this change, boards that use the audio-codec property will show
the following error message during boot when using the
imx_v6_v7_defconfig and spdif audio is not working:

Since commit 17d210018914 ("ARM: imx: Allow user to disable pinctrl"),
the CONFIG_PINCTRL option is no longer implicitly selected, causing
several i.MX SoC pinctrl drivers no longer getting selected by default.
This causes boot regressions on the ARMv4, ARMv5, ARMv6 and ARMv7
i.MX SoCs.
Fix it by selecting CONFIG_PINCTRL as before.
This defeats the purpose of 7d210018914 ("ARM: imx: Allow user to disable
pinctrl"), but it is the less invasive fix for the boot regressions.
The attempt to build Layerscape without pinctrl can still be explored
later as suggested by Arnd:
"Overall, my best advice here is still to not change the way
i.MX pinctrl works at all, but just fix Layerscape to not depend
on i.MX. The reason for the 'select' here is clearly that the
i.MX machines would fail to boot without pinctrl, and changing
that because of Layerscape seems backwards."

The continual trickle of small conversion patches is grating on me, and
is really not helping. Just get rid of the 'remove_new' member
function, which is just an alias for the plain 'remove', and had a
comment to that effect:
/*
* .remove_new() is a relic from a prototype conversion of .remove().
* New drivers are supposed to implement .remove(). Once all drivers are
* converted to not use .remove_new any more, it will be dropped.
*/
This was just a tree-wide 'sed' script that replaced '.remove_new' with
'.remove', with some care taken to turn a subsequent tab into two tabs
to make things line up.
I did do some minimal manual whitespace adjustment for places that used
spaces to line things up.
Then I just removed the old (sic) .remove_new member function, and this
is the end result. No more unnecessary conversion noise.

Pull SoC devicetree updates from Arnd Bergmann:
"This release adds the devicetree files for an impressive number of new
SoC variants, though as expected these are all related to others we
already support:
- The microchip sam9x7 devicetree is now added, after the device
driver and platform code has already made it in. This is likely the
last ARMv5 (!) platform to ever get added, updating the 20+ year
old at91/sam9 platform with DDR3 memory and gigabit ethernet.
- On the Apple platform, there are now devicetree files for a number
of A-series SoCs in addition to the M-series ones, these are used
primarily in phones and tablets, but are closely related to the
already supported chips.
- Samsung Exynos 8895 and Exynos 990 are more phone SoCs used in
older Samsung Galaxy phones.
- Qualcomm Snapdragon 778G (SM7325) is another phone SoC, closely
related to the Snapdragon 7c+ Gen 3 (SC7280) used in low-end
laptops.
- Rockchip RK3528 and RK3576 are new variants of their TV box and
Tablet chips, still using the older ARMv8.0 cores from
RK3328/RK3399 but with a newer process and other improvements from
the RK35xx (otherwise ARMv8.2) chips. RK3566T and RK3399-S are also
added, these are just lower-cost versions of their normal
counterparts.
- TI J742S2 is a feature-reduced version of the J784s4
industrial/automotive SoC, with fewer CPU cores.
- Sophgo SG2002 is an embedded SoC with one RISC-V (C906) and one ARM
(Cortex-A53) core, at this point support is only added for running
on the RISC-V side on the LicheeRV Nano board.
A total of 92 new .dts files describing individual machines is added,
which must be a new record. The majority of these is for the newly
added chips above, notably all the Apple phones and tablets. The other
new machines include nine industrial/embedded boards with NXP i.MX6 or
i.MX8 SoCs, eight for Rockchips RK35XX and one or two each for
Rockchips RV1109, RK3308, Allwinner A33, Tegra 234, Qualcomm
qcs9100/sc8280xp/x1e80100, TI AM625 and Starfive JH7110.
As usual there are also many newly added features in existing boards
as well as cleanups and minor bugfixes"

git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip
Pull timer updates from Thomas Gleixner:
"A rather large update for timekeeping and timers:
- The final step to get rid of auto-rearming posix-timers
posix-timers are currently auto-rearmed by the kernel when the
signal of the timer is ignored so that the timer signal can be
delivered once the corresponding signal is unignored.
This requires to throttle the timer to prevent a DoS by small
intervals and keeps the system pointlessly out of low power states
for no value. This is a long standing non-trivial problem due to
the lock order of posix-timer lock and the sighand lock along with
life time issues as the timer and the sigqueue have different life
time rules.
Cure this by:
- Embedding the sigqueue into the timer struct to have the same
life time rules. Aside of that this also avoids the lookup of
the timer in the signal delivery and rearm path as it's just a
always valid container_of() now.
- Queuing ignored timer signals onto a seperate ignored list.
- Moving queued timer signals onto the ignored list when the
signal is switched to SIG_IGN before it could be delivered.
- Walking the ignored list when SIG_IGN is lifted and requeue the
signals to the actual signal lists. This allows the signal
delivery code to rearm the timer.
This also required to consolidate the signal delivery rules so they
are consistent across all situations. With that all self test
scenarios finally succeed.
- Core infrastructure for VFS multigrain timestamping
This is required to allow the kernel to use coarse grained time
stamps by default and switch to fine grained time stamps when inode
attributes are actively observed via getattr().
These changes have been provided to the VFS tree as well, so that
the VFS specific infrastructure could be built on top.
- Cleanup and consolidation of the sleep() infrastructure
- Move all sleep and timeout functions into one file
- Rework udelay() and ndelay() into proper documented inline
functions and replace the hardcoded magic numbers by proper
defines.
- Rework the fsleep() implementation to take the reality of the
timer wheel granularity on different HZ values into account.
Right now the boundaries are hard coded time ranges which fail
to provide the requested accuracy on different HZ settings.
- Update documentation for all sleep/timeout related functions
and fix up stale documentation links all over the place
- Fixup a few usage sites
- Rework of timekeeping and adjtimex(2) to prepare for multiple PTP
clocks
A system can have multiple PTP clocks which are participating in
seperate and independent PTP clock domains. So far the kernel only
considers the PTP clock which is based on CLOCK TAI relevant as
that's the clock which drives the timekeeping adjustments via the
various user space daemons through adjtimex(2).
The non TAI based clock domains are accessible via the file
descriptor based posix clocks, but their usability is very limited.
They can't be accessed fast as they always go all the way out to
the hardware and they cannot be utilized in the kernel itself.
As Time Sensitive Networking (TSN) gains traction it is required to
provide fast user and kernel space access to these clocks.
The approach taken is to utilize the timekeeping and adjtimex(2)
infrastructure to provide this access in a similar way how the
kernel provides access to clock MONOTONIC, REALTIME etc.
Instead of creating a duplicated infrastructure this rework
converts timekeeping and adjtimex(2) into generic functionality
which operates on pointers to data structures instead of using
static variables.
This allows to provide time accessors and adjtimex(2) functionality
for the independent PTP clocks in a subsequent step.
- Consolidate hrtimer initialization
hrtimers are set up by initializing the data structure and then
seperately setting the callback function for historical reasons.
That's an extra unnecessary step and makes Rust support less
straight forward than it should be.
Provide a new set of hrtimer_setup*() functions and convert the
core code and a few usage sites of the less frequently used
interfaces over.
The bulk of the htimer_init() to hrtimer_setup() conversion is
already prepared and scheduled for the next merge window.
- Drivers:
- Ensure that the global timekeeping clocksource is utilizing the
cluster 0 timer on MIPS multi-cluster systems.
Otherwise CPUs on different clusters use their cluster specific
clocksource which is not guaranteed to be synchronized with
other clusters.
- Mostly boring cleanups, fixes, improvements and code movement"

Pull vdso data page handling updates from Thomas Gleixner:
"First steps of consolidating the VDSO data page handling.
The VDSO data page handling is architecture specific for historical
reasons, but there is no real technical reason to do so.
Aside of that VDSO data has become a dump ground for various
mechanisms and fail to provide a clear separation of the
functionalities.
Clean this up by:
- consolidating the VDSO page data by getting rid of architecture
specific warts especially in x86 and PowerPC.
- removing the last includes of header files which are pulling in
other headers outside of the VDSO namespace.
- seperating timekeeping and other VDSO data accordingly.
Further consolidation of the VDSO page handling is done in subsequent
changes scheduled for the next merge window.
This also lays the ground for expanding the VDSO time getters for
independent PTP clocks in a generic way without making every
architecture add support seperately"

Pull interrupt subsystem updates from Thomas Gleixner:
"Tree wide:
- Make nr_irqs static to the core code and provide accessor functions
to remove existing and prevent future aliasing problems with local
variables or function arguments of the same name.
Core code:
- Prevent freeing an interrupt in the devres code which is not
managed by devres in the first place.
- Use seq_put_decimal_ull_width() for decimal values output in
/proc/interrupts which increases performance significantly as it
avoids parsing the format strings over and over.
- Optimize raising the timer and hrtimer soft interrupts by using the
'set bit only' variants instead of the combined version which
checks whether ksoftirqd should be woken up. The latter is a
pointless exercise as both soft interrupts are raised in the
context of the timer interrupt and therefore never wake up
ksoftirqd.
- Delegate timer/hrtimer soft interrupt processing to a dedicated
thread on RT.
Timer and hrtimer soft interrupts are always processed in ksoftirqd
on RT enabled kernels. This can lead to high latencies when other
soft interrupts are delegated to ksoftirqd as well.
The separate thread allows to run them seperately under a RT
scheduling policy to reduce the latency overhead.
Drivers:
- New drivers or extensions of existing drivers to support Renesas
RZ/V2H(P), Aspeed AST27XX, T-HEAD C900 and ATMEL sam9x7 interrupt
chips
- Support for multi-cluster GICs on MIPS.
MIPS CPUs can come with multiple CPU clusters, where each CPU
cluster has its own GIC (Generic Interrupt Controller). This
requires to access the GIC of a remote cluster through a redirect
register block.
This is encapsulated into a set of helper functions to keep the
complexity out of the actual code paths which handle the GIC
details.
- Support for encrypted guests in the ARM GICV3 ITS driver
The ITS page needs to be shared with the hypervisor and therefore
must be decrypted.
- Small cleanups and fixes all over the place"
