Update dt-bindings to add primary controller of QCS615 to USB
DWC3 controller list.
Although this controller has a QUSB2 Phy, it belongs to a
generation of SoCs like SDM670/SDM845/SM6350 where DP/DM is
used for wakeup instead of qusb2_phy interrupt.

Extend the USB+DP combo QMP PHY driver to support the SAR2130P platform.
It mosly follows the SM8550 QMP PHY, but the QSERDES programming
differs, most likely because of the parent clock rate differences.
NOTE: The DP part wasn't yet tested, but it is not possible to support
just the USB part of the PHY. DP part might require additional fixes
later.

Currently, the calcuation for fld_tg_code is based on a lookup table,
but there are gaps in the lookup table, and frequencies in these
gaps may not properly use the correct divider. Based on the description
of FLD_CK_DIV, the internal PLL frequency should be less than 50 MHz,
so directly calcuate the value of FLD_CK_DIV from pixclk.
This allow for proper calcuation of any pixel clock and eliminates a
few gaps in the LUT.
Since the value of the int_pllclk is in Hz, do the fixed-point
math in Hz to achieve a more accurate value and reduces the complexity
of the caluation to 24MHz * (256 / int_pllclk).

There are a series of for-loops which check various values of P and S
for the integer divder PLL. The for loops search all entries and use
the one closest to the nominal, but it continues to searches through
all for loops even after the nominal is achieved. Ending when the
nominal value is found stops wasting time, since it will not find
a better value than a deviation of 0 Hz.

to this being a fixed regulator.

Pull i2c component probing support from Wolfram Sang:
"Add OF component probing.
Some devices are designed and manufactured with some components having
multiple drop-in replacement options. These components are often
connected to the mainboard via ribbon cables, having the same signals
and pin assignments across all options. These may include the display
panel and touchscreen on laptops and tablets, and the trackpad on
laptops. Sometimes which component option is used in a particular
device can be detected by some firmware provided identifier, other
times that information is not available, and the kernel has to try to
probe each device.
Instead of a delicate dance between drivers and device tree quirks,
this change introduces a simple I2C component probe function. For a
given class of devices on the same I2C bus, it will go through all of
them, doing a simple I2C read transfer and see which one of them
responds. It will then enable the device that responds"

The point behind strscpy() was to once and for all avoid all the
problems with 'strncpy()' and later broken "fixed" versions like
strlcpy() that just made things worse.
So strscpy not only guarantees NUL-termination (unlike strncpy), it also
doesn't do unnecessary padding at the destination. But at the same time
also avoids byte-at-a-time reads and writes by _allowing_ some extra NUL
writes - within the size, of course - so that the whole copy can be done
with word operations.
It is also stable in the face of a mutable source string: it explicitly
does not read the source buffer multiple times (so an implementation
using "strnlen()+memcpy()" would be wrong), and does not read the source
buffer past the size (like the mis-design that is strlcpy does).
Finally, the return value is designed to be simple and unambiguous: if
the string cannot be copied fully, it returns an actual negative error,
making error handling clearer and simpler (and the caller already knows
the size of the buffer). Otherwise it returns the string length of the
result.
However, there was one final stability issue that can be important to
callers: the stability of the destination buffer.
In particular, the same way we shouldn't read the source buffer more
than once, we should avoid doing multiple writes to the destination
buffer: first writing a potentially non-terminated string, and then
terminating it with NUL at the end does not result in a stable result
buffer.
Yes, it gives the right result in the end, but if the rule for the
destination buffer was that it is _always_ NUL-terminated even when
accessed concurrently with updates, the final byte of the buffer needs
to always _stay_ as a NUL byte.
[ Note that "final byte is NUL" here is literally about the final byte
in the destination array, not the terminating NUL at the end of the
string itself. There is no attempt to try to make concurrent reads and
writes give any kind of consistent string length or contents, but we
do want to guarantee that there is always at least that final
terminating NUL character at the end of the destination array if it
existed before ]
This is relevant in the kernel for the tsk->comm[] array, for example.
Even without locking (for either readers or writers), we want to know
that while the buffer contents may be garbled, it is always a valid C
string and always has a NUL character at 'comm[TASK_COMM_LEN-1]' (and
never has any "out of thin air" data).
So avoid any "copy possibly non-terminated string, and terminate later"
behavior, and write the destination buffer only once.

Pull more io_uring updates from Jens Axboe:
- Remove a leftover struct from when the cqwait registered waiting was
transitioned to regions.
- Fix for an issue introduced in this merge window, where nop->fd might
be used uninitialized. Ensure it's always set.
- Add capping of the task_work run in local task_work mode, to prevent
bursty and long chains from adding too much latency.
- Work around xa_store() leaving ->head non-NULL if it encounters an
allocation error during storing. Just a debug trigger, and can go
away once xa_store() behaves in a more expected way for this
condition. Not a major thing as it basically requires fault injection
to trigger it.
- Fix a few mapping corner cases
- Fix KCSAN complaint on reading the table size post unlock. Again not
a "real" issue, but it's easy to silence by just keeping the reading
inside the lock that protects it.
* tag 'io_uring-6.13-20242901' of git://git.kernel.dk/linux:
io_uring/tctx: work around xa_store() allocation error issue
io_uring: fix corner case forgetting to vunmap

git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux
Pull sh updates from John Paul Adrian Glaubitz:
"Two small fixes.
The first one by Huacai Chen addresses a runtime warning when
CONFIG_CPUMASK_OFFSTACK and CONFIG_DEBUG_PER_CPU_MAPS are selected
which occurs because the cpuinfo code on sh incorrectly uses NR_CPUS
when iterating CPUs instead of the runtime limit nr_cpu_ids.
A second fix by Dan Carpenter fixes a use-after-free bug in
register_intc_controller() which occurred as a result of improper
error handling in the interrupt controller driver code when
registering an interrupt controller during plat_irq_setup() on sh"
* tag 'sh-for-v6.13-tag1' of git://git.kernel.org/pub/scm/linux/kernel/git/glaubitz/sh-linux:
sh: intc: Fix use-after-free bug in register_intc_controller()
