It seems that when the driver is built-in, the HID bus is
initialized after the driver is loaded, which whould cause
module_hid_driver() to fail.
Fix this by registering the driver after the HID bus using
late_initcall() in accordance with other hwmon HID drivers.

Using -MD without -MP causes build failures when a header file is deleted
or moved. With -MP, the compiler will emit phony targets for the header
files it lists as dependencies, and the Makefiles won't refuse to attempt
to rebuild a C unit which no longer includes the deleted header.

kvm-master
KVM fixes for 6.7-rcN:
- When checking if a _running_ vCPU is "in-kernel", i.e. running at CPL0,
get the CPL directly instead of relying on preempted_in_kernel, which
is valid if and only if the vCPU was preempted, i.e. NOT running.
- Set .owner for various KVM file_operations so that files refcount the
KVM module until KVM is done executing _all_ code, including the last
few instructions of kvm_put_kvm(). And then revert the misguided
attempt to rely on "struct kvm" refcounts to pin KVM-the-module.
- Fix a benign "return void" that was recently introduced.

Pull ARM SoC fixes from Arnd Bergmann:
"Most of the changes are devicetree fixes for NXP, Mediatek, Rockchips
Arm machines as well as Microchip RISC-V, and most of these address
build-time warnings for spec violations and other minor issues. One of
the Mediatek warnings was enabled by default and prevented a clean
build.
The ones that address serious runtime issues are all on the i.MX
platform:
- a boot time panic on imx8qm
- USB hanging under load on imx8
- regressions on the imx93 ethernet phy
Code fixes include a minor error handling for the i.MX PMU driver, and
a number of firmware driver fixes:
- OP-TEE fix for supplicant based device enumeration, and a new sysfs
attribute to needed to fix a race against userspace
- Arm SCMI fix for possible truncation/overflow in the frequency
computations
- Multiple FF-A fixes for the newly added notification support"

git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace
Pull tracing fixes from Steven Rostedt:
- Snapshot buffer issues:
1. When instances started allowing latency tracers, it uses a
snapshot buffer (another buffer that is not written to but swapped
with the main buffer that is). The snapshot buffer needs to be the
same size as the main buffer. But when the snapshot buffers were
added to instances, the code to make the snapshot equal to the
main buffer still was only doing it for the main buffer and not
the instances.
2. Need to stop the current tracer when resizing the buffers.
Otherwise there can be a race if the tracer decides to make a
snapshot between resizing the main buffer and the snapshot buffer.
3. When a tracer is "stopped" in disables both the main buffer and
the snapshot buffer. This needs to be done for instances and not
only the main buffer, now that instances also have a snapshot
buffer.
- Buffered event for filtering issues:
When filtering is enabled, because events can be dropped often, it is
quicker to copy the event into a temp buffer and write that into the
main buffer if it is not filtered or just drop the event if it is,
than to write the event into the ring buffer and then try to discard
it. This temp buffer is allocated and needs special synchronization
to do so. But there were some issues with that:
1. When disabling the filter and freeing the buffer, a call to all
CPUs is required to stop each per_cpu usage. But the code called
smp_call_function_many() which does not include the current CPU.
If the task is migrated to another CPU when it enables the CPUs
via smp_call_function_many(), it will not enable the one it is
currently on and this causes issues later on. Use
on_each_cpu_mask() instead, which includes the current CPU.
2.When the allocation of the buffered event fails, it can give a
warning. But the buffered event is just an optimization (it's
still OK to write to the ring buffer and free it). Do not WARN in
this case.
3.The freeing of the buffer event requires synchronization. First a
counter is decremented to zero so that no new uses of it will
happen. Then it sets the buffered event to NULL, and finally it
frees the buffered event. There's a synchronize_rcu() between the
counter decrement and the setting the variable to NULL, but only a
smp_wmb() between that and the freeing of the buffer. It is
theoretically possible that a user missed seeing the decrement,
but will use the buffer after it is free. Another
synchronize_rcu() is needed in place of that smp_wmb().
- ring buffer timestamps on 32 bit machines
The ring buffer timestamp on 32 bit machines has to break the 64 bit
number into multiple values as cmpxchg is required on it, and a 64
bit cmpxchg on 32 bit architectures is very slow. The code use to
just use two 32 bit values and make it a 60 bit timestamp where the
other 4 bits were used as counters for synchronization. It later came
known that the timestamp on 32 bit still need all 64 bits in some
cases. So 3 words were created to handle the 64 bits. But issues
arised with this:
1. The synchronization logic still only compared the counter with
the first two, but not with the third number, so the
synchronization could fail unknowingly.
2. A check on discard of an event could race if an event happened
between the discard and updating one of the counters. The counter
needs to be updated (forcing an absolute timestamp and not to use
a delta) before the actual discard happens.

sdio_in() returns a value returned from sdio_readb(). The latter returns
u8. So should the former. Therefore, switch sdio_in() return type to u8
and all its callers too.

do_rw_io()'s is_write parameter is boolean, but typed int. Switch to the
former, so that it's obvious. (And the two users too.)

Parse the OPP table from the device tree and use dev_pm_opp_set_rate()
instead of clk_set_rate() to allow making performance state votes
specified in the OPP table (e.g. for power domains and interconnects).
Without an OPP table in the device tree this will behave just as before
this patch.

Document power-domains, operating-points-v2 and interconnects to allow
making performance state votes for certain clock frequencies of the UART
DM controller. The interconnect path to DRAM is needed when UART DM is
used together with a DMA engine.
Voting for these shared resources is necessary to guarantee performance
with power management enabled. Otherwise these resources might run at
minimal performance state which is not sufficient for certain UART
baud rates.

sparse reports multiple problems with address space type.
Most problems are linked to missing __iomem qualifier.
Others are caused by dereferencing __iomem addresses.
Fix all this by adding missing __iomem and using ioread32be().

Refer ARM DDI 0487I.a ID081822, D17.3.8, DBGDTRTX_EL0,
"If TXfull is set to 1, set DTRRX and DTRTX to UNKNOWN"
Thus one should always check for TXfull condition before hvc can be
used as an early console. This is similar to what is being done
today in hvc_dcc_console_init() and hvc_dcc_init().
The count 0x4000000 has been obtained from uboot (v2024.01-rc3)
drivers/serial/arm_dcc.c "TIMEOUT_COUNT".
It reads the dcc status and waits for 0x4000000 times for the TX Fifo
to be available before returning an error. Thus, it will prevent DCC
to be used as early console.

When using the serial port as RS485 port, the tx statemachine is used to
control the RTS pin to drive the RS485 transceiver TX_EN pin. When the
TTY port is closed in the middle of a transmission (for instance during
userland application crash), imx_uart_shutdown disables the interface
and disables the Transmission Complete interrupt. afer that,
imx_uart_stop_tx bails on an incomplete transmission, to be retriggered
by the TC interrupt. This interrupt is disabled and therefore the tx
statemachine never transitions out of SEND. The statemachine is in
deadlock now, and the TX_EN remains low, making the interface useless.
imx_uart_stop_tx now checks for incomplete transmission AND whether TC
interrupts are enabled before bailing to be retriggered. This makes sure
the state machine handling is reached, and is properly set to
WAIT_AFTER_SEND.

git://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip into arm/fixes
Devicetree fixes for the 6.7-cycle.
All over the place this time. From adapting the size of the vdec nodes
on rk3328 and rk3399, fixing some wrong pinctrl settings on rk3128 and
the Turing RK1 board, emmc-settings fixes on rk3588 and interrupt-name
mishaps, down to some dt-cleanups.
Also this adds the missing rockchip,rk3588-pmugrf compatible to the soc
grf binding, that I somehow messed up during the pull requests for the
-rc1 . At least with it included the dt-checker is happier.
