Commit ac0126a01735 ("soc: qcom: cmd-db: replace strncpy() with
strscpy_pad()") breaks booting on my sc7280-herobrine-herobrine
device. From printouts I see that at bootup the function is called
with an id of "lnbclka2" which is 8 bytes big.
Previously all 8 bytes of this string were copied to the
destination. Now only 7 bytes will be copied since strscpy_pad() saves
a byte for '\0' termination.
We don't need the '\0' termination in the destination. Let's go back
to strncpy(). According to the warning:
If a caller is using non-NUL-terminated strings, strncpy() can still
be used, but destinations should be marked with the __nonstring
attribute to avoid future compiler warnings.
...so we'll do that.
While we're at it, let's change the query array to use
"sizeof(ent->id)" so it can't possibly go out of sync with our later
copy.

Most layerscapes provide a security fuse processor where the vendor
will store a unique id per part. Unfortunately, we cannot use the
corresponding efuse driver because this driver needs to be ready
early during the boot phase. To get the unique identifier, we just
need to access two registers. Thus we just search the device tree
for the corresponding device, map its memory to read the id and then
unmap it again.
Because it is likely that the offset within the fuses is dependent
on the SoC, we need a per SoC data. Also, the compatible string is
different among the SoCs. For now, this add support for the LS1028A
SoC.

As a result, all of the mutex mod arrays have been changed to use the

In order to allow multiple modules to operate MUTEX hardware through

In addition, 2 generic interface "mtk_mutex_write_mod" and

the "mtk_mutex_add_comp" and "mtk_mutex_remove_comp" pair originally

Disable MMIO tracing for GENI SE driver to prevent excessive
logging. Any access over serial console would involve a lot of
TX and RX register accesses (and few others), so these MMIO
read/write trace events in these drivers cause a lot of unwanted
noise because of the high frequency of such operations and it is
not very useful tracing these events for such drivers.
Given we want to enable these trace events on development devices
(maybe not production devices) where performance also really
matters so that we don't regress other components by wasting CPU
cycles and memory collecting these traces, it makes more sense to
disable these traces from such drivers.
Also another reason to disable these traces would be to prevent
recursive tracing when we display the trace buffer containing
these MMIO trace events since writing onto serial console would
further record MMIO traces.

In the PMIC Wrapper driver each PMIC has its own regmap configuration
and its own pwrap_{read/write}() callbacks, but it's just about either
a 32 bits vs 16 bits register, and only one of them uses 32bits regs:
this means that the same ops are assigned over and over again to all
of the supported PMICs.
It is therefore possible to avoid reassigning the same things over
and over, reducing the amount of lines, without any impact on human
readability of this driver: add a pwrap_slv_regops structure and
move the callbacks and regmap_config pointer in there instead.
This allows to assign just one pointer to that shared data in the
per-pmic struct pwrap_slv_type.

- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no reported
problems.
Note, there are 3 merge conflicts when merging this with your tree:
- MAINTAINERS, should be easy to resolve
- drivers/slimbus/qcom-ctrl.c, should be straightforward
resolution
- drivers/misc/lkdtm/stackleak.c, not an easy resolution. This
has been noted in the linux-next tree for a while, and
resolved there, here's a link to the resolution that Stephen
came up with and that Kees says is correct:
https://lore.kernel.org/r/20220509185344.3fe1a354@canb.auug.org.au
I will be glad to provide a merge point that contains these resolutions
if that makes things any easier for you.

Merge tag 'char-misc-5.19-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/char-misc
Pull char / misc / other smaller driver subsystem updates from Greg KH:
"Here is the large set of char, misc, and other driver subsystem
updates for 5.19-rc1. The merge request for this has been delayed as I
wanted to get lots of linux-next testing due to some late arrivals of
changes for the habannalabs driver.
Highlights of this merge are:
- habanalabs driver updates for new hardware types and fixes and
other updates
- IIO driver tree merge which includes loads of new IIO drivers and
cleanups and additions
- PHY driver tree merge with new drivers and small updates to
existing ones
- interconnect driver tree merge with fixes and updates
- soundwire driver tree merge with some small fixes
- coresight driver tree merge with small fixes and updates
- mhi bus driver tree merge with lots of updates and new device
support
- firmware driver updates
- fpga driver updates
- lkdtm driver updates (with a merge conflict, more on that below)
- extcon driver tree merge with small updates
- lots of other tiny driver updates and fixes and cleanups, full
details in the shortlog.
All of these have been in linux-next for almost 2 weeks with no
reported problems"

This is the second part of the general SoC updates, containing
everything that did not make it in the initial pull request,
or that came in as a bugfix later.
- Devicetree updates for SoCFPGA, ASPEED, AT91 and Rockchip, including
a new machine using an ASPEED BMC.
- More DT fixes from Krzysztof Kozlowski across platforms
- A new SoC platform for the GXP baseboard management controller,
used in current server products from HPE.

The second part of the multiplatform changes now converts the
Intel/Marvell PXA platform along with the rest. The patches went through
several rebases before the merge window as bugs were found, so they
remained separate.
This has to touch a lot of drivers, in particular the touchscreen,
pcmcia, sound and clk bits, to detach the driver files from the
platform and board specific header files.
