cdd30ebb1b module: Convert symbol namespace to string literal
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

e70140ba0d Get rid of 'remove_new' relic from platform driver struct
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.

d8b78066f4 TTY / Serial driver updates for 6.13-rc1
Here is a small set of tty and serial driver updates for 6.13-rc1.
 Nothing major at all this time, only some small changes:
   - few device tree binding updates
   - 8250_exar serial driver updates
   - imx serial driver updates
   - sprd_serial driver updates
   - other tiny serial driver updates, full details in the shortlog
 
 All of these have been in linux-next for a while with one reported
 issue, but that commit has now been reverted.

2eff01ee28 Char/Misc/IIO/Whatever driver subsystem updates for 6.13-rc1
Here is the "big and hairy" char/misc/iio and other small driver
 subsystem updates for 6.13-rc1.  Sorry for doing this at the end of the
 merge window, conference and holiday travel got in the way on my side
 (hence the 5am pull request emails...)
 
 Loads of things in here, and even a fun merge conflict!
   - rust misc driver bindings and other rust changes to make misc
     drivers actually possible.  I think this is the tipping point,
     expect to see way more rust drivers going forward now that these
     bindings are present.  Next merge window hopefully we will have pci
     and platform drivers working, which will fully enable almost all
     driver subsystems to start accepting (or at least getting) rust
     drivers.  This is the end result of a lot of work from a lot of
     people, congrats to all of them for getting this far, you've proved
     many of us wrong in the best way possible, working code :)
   - IIO driver updates, too many to list individually, that subsystem
     keeps growing and growing...
   - Interconnect driver updates
   - nvmem driver updates
   - pwm driver updates
   - platform_driver::remove() fixups, loads of them
   - counter driver updates
   - misc driver updates (keba?)
   - binder driver updates and fixes
   - loads of other small char/misc/etc driver updates and additions,
     full details in the shortlog.
 
 Note, there is a semi-hairy rust merge conflict when pulling this.  The
 resolution has been in linux-next for a while and can be seen here:
 	https://lore.kernel.org/all/20241111173459.2646d4af@canb.auug.org.au/
 
 All of these have been in linux-next for a while, with no other reported
 issues other than that merge conflict.

55cb93fd24 Driver core changes for 6.13-rc1
Here is a small set of driver core changes for 6.13-rc1.
 
 Nothing major for this merge cycle, except for the 2 simple merge
 conflicts are here just to make life interesting.
 
 Included in here are:
   - sysfs core changes and preparations for more sysfs api cleanups that
     can come through all driver trees after -rc1 is out
   - fw_devlink fixes based on many reports and debugging sessions
   - list_for_each_reverse() removal, no one was using it!
   - last-minute seq_printf() format string bug found and fixed in many
     drivers all at once.
   - minor bugfixes and changes full details in the shortlog
 
 As mentioned above, there is 2 merge conflicts with your tree, one is
 where the file is removed (easy enough to resolve), the second is a
 build time error, that has been found in linux-next and the fix can be
 seen here:
 	https://lore.kernel.org/r/20241107212645.41252436@canb.auug.org.au
 
 Other than that, the changes here have been in linux-next with no other
 reported issues.

14d0e1a09f soc: driver updates for 6.12
Nothing particular important in the SoC driver updates, just the usual
 improvements to for drivers/soc and a couple of subsystems that don't
 fit anywhere else:
 
  - The largest set of updates is for Qualcomm SoC drivers, extending the
    set of supported features for additional SoCs in the QSEECOM, LLCC
    and socinfo drivers.a
 
  - The ti_sci firmware driver gains support for power managment
 
  - The drivers/reset subsystem sees a rework of the microchip
    sparx5 and amlogic reset drivers to support additional chips,
    plus a few minor updates on other platforms
 
  - The SCMI firmware interface driver gains support for two protocol
    extensions, allowing more flexible use of the shared memory area
    and new DT binding properties for configurability.
 
  - Mediatek SoC drivers gain support for power managment on the MT8188
    SoC and a new driver for DVFS.
 
  - The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
    and a few bugfixes
 
  - The Hisilicon Kunpeng HCCS driver gains support for configuring
    lanes through sysfs
 
 Finally, there are cleanups and minor fixes for drivers/soc, drivers/bus,
 and drivers/memory, including changing back the .remove_new callback
 to .remove, as well as a few other updates for freescale (powerpc)
 soc drivers, NXP i.MX soc drivers, cznic turris platform driver, memory
 controller drviers, TI OMAP SoC drivers, and Tegra firmware drivers

Merge tag 'soc-drivers-6.13' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull SoC driver updates from Arnd Bergmann:
 "Nothing particular important in the SoC driver updates, just the usual
  improvements to for drivers/soc and a couple of subsystems that don't
  fit anywhere else:

   - The largest set of updates is for Qualcomm SoC drivers, extending
     the set of supported features for additional SoCs in the QSEECOM,
     LLCC and socinfo drivers.a

   - The ti_sci firmware driver gains support for power managment

   - The drivers/reset subsystem sees a rework of the microchip sparx5
     and amlogic reset drivers to support additional chips, plus a few
     minor updates on other platforms

   - The SCMI firmware interface driver gains support for two protocol
     extensions, allowing more flexible use of the shared memory area
     and new DT binding properties for configurability.

   - Mediatek SoC drivers gain support for power managment on the MT8188
     SoC and a new driver for DVFS.

   - The AMD/Xilinx ZynqMP SoC drivers gain support for system reboot
     and a few bugfixes

   - The Hisilicon Kunpeng HCCS driver gains support for configuring
     lanes through sysfs

  Finally, there are cleanups and minor fixes for drivers/{soc, bus,
  memory}, including changing back the .remove_new callback to .remove,
  as well as a few other updates for freescale (powerpc) soc drivers,
  NXP i.MX soc drivers, cznic turris platform driver, memory controller
  drviers, TI OMAP SoC drivers, and Tegra firmware drivers"

f06e108a3d Compiler Attributes: disable __counted_by for clang < 19.1.3
This patch disables __counted_by for clang versions < 19.1.3 because
of the two issues listed below. It does this by introducing
CONFIG_CC_HAS_COUNTED_BY.

1. clang < 19.1.2 has a bug that can lead to __bdos returning 0:
https://github.com/llvm/llvm-project/pull/110497

2. clang < 19.1.3 has a bug that can lead to __bdos being off by 4:

7d6f7cfc34 Reset controller updates for v6.13
* Split the Amlogic reset-meson driver into platform and auxiliary
   bus drivers. Add support for the reset controller in the G12 and
   SM1 audio clock controllers.
 * Replace the list of boolean parameters to the internal
   reset_control_get functions with an enum reset_flags bitfield,
   to make the code more self-descriptive.
 * Add devres helpers to request pre-deasserted (and automatically
   re-asserting during cleanup) reset controls. This allows reducing
   boilerplate in drivers that deassert resets for the lifetime of a
   device.
 * Use the new auto-deasserting devres helpers in reset-uniphier-glue
   as an example.
 * Add support for the LAN966x PCI device in drivers/misc, as a
   dependency for the following reset-microchip-sparx5 patches.
 * Add support for being used on the LAN966x PCI device to the
   reset-microchip-sparx5 driver.
 
 Commit 86f134941a ("MAINTAINERS: Add the Microchip LAN966x PCI driver
 entry") introduces a trivial merge conflict with commit 7280f01e79

49988a7975 mei: vsc: Do not re-enable interrupt from vsc_tp_reset()
The only 2 callers of vsc_tp_reset() are:

1. mei_vsc_hw_reset(), which immediataly calls vsc_tp_intr_disable()
   afterwards.

2. vsc_tp_shutdown() which immediately calls free_irq() afterwards.

So neither actually wants the interrupt to be enabled after resetting
the chip and having the interrupt enabled for a short time afer
the reset is undesirable.

Drop the enable_irq() call from vsc_tp_reset(), so that the interrupt
is left disabled after vsc_tp_reset().

cf3e10cc0e misc: lan966x_pci: Fix dtc warn 'Missing interrupt-parent'
dtc generates the following warning when building the LAN966x devicetree
overlay (lan966x_pci.dtso):
  Warning (interrupts_property): /fragment@0/__overlay__/pci-ep-bus@0/oic@e00c0120: Missing interrupt-parent

The oic interrupt parent is the PCI device itself. The PCI device node
is the node on which the dtbo will be applied and this node already has
properties needed.

In order to remove the warning, add the missing properties in the
overlay fragment node. Properties in this node will not be added when
the overlay is applied (which is what we expect) but makes dtc happy.

185686beb4 misc: Add support for LAN966x PCI device
Add a PCI driver that handles the LAN966x PCI device using a device-tree
overlay. This overlay is applied to the PCI device DT node and allows to
describe components that are present in the device.

The memory from the device-tree is remapped to the BAR memory thanks to
"ranges" properties computed at runtime by the PCI core during the PCI
enumeration.

The PCI device itself acts as an interrupt controller and is used as the
parent of the internal LAN966x interrupt controller to route the
interrupts to the assigned PCI INTx interrupt.

339cb28b9e eeprom: at24: add ST M24256E Additional Write lockable page support
The ST M24256E behaves as a regular M24C256, except for the E variant
which uses up another I2C address for Additional Write lockable page.
This page is 64 Bytes long and can contain additional data. Add entry
for it, so users can describe that page in DT. Note that users still
have to describe the main M24C256 area separately as that is on separate
I2C address from this page.

Unlike M24C32-D and M24C64-D, this part is specifically ST and does not
have any comparable M24* counterparts from other vendors, hence the st,
vendor prefix. Furthermore, the part name is M24256E without C between
the 24 and 256, this is not a typo. Finally, there is M24C256-D part,
which does contain 32 Bytes long Additional Write lockable page, which
is a different part and not supported by this patch.

c6576d9195 misc: keba: Support EEPROM sections as separate devices
The main EEPROM of KEBA CP500 devices is divided into two sections. One
section for type label data like device name, order number, serial
number and so on. The second section is reserved for arbitrary data
stored by the user.

The two sections have a defined range. The first 3 kB for the type label
and the remaining 1 kB for user data. The type label is written during
production and can fill up the whole 3 kB. Thus, the range is fixed and
cannot be changed dynamically.

The two sections cannot be presented as NVMEM cells. A NVMEM cell is
always read and written at once, because the data presented to the user
can differ from the data stored in the physical NVMEM cell. Thus, NVMEM
cells would lead to reading 3 kB for every type label access, even if
only the device name is read. So performance would suffer. But it is
also an indication that NVMEM cells are designed for small data cells
within NVMEM devices.

Register separate NVMEM devices for every section. This enables safe
access to every section. Also different access rights are then possible.

More info can be found on page 6 of the AT93C46 datasheet (linked below).
Similar notes are found in other 93xx6 datasheets.

In summary the read operation for a 93Cx6 EEPROM is:
Write to EEPROM:	110[A5-A0]	(9 bits)
Read from EEPROM:	0[D15-D0]	(17 bits)

Where:
	110 is the start bit and READ OpCode
	[A5-A0] is the address to read from
	0 is a "dummy bit" preceding the actual data
	[D15-D0] is the actual data.

Looking at the READ timing diagrams in the 93Cx6 datasheets the dummy
bit should be clocked out on the last address bit clock cycle meaning it
should be discarded naturally.

However, depending on the hardware configuration sometimes this dummy
bit is not discarded. This is the case with Exar PCI UARTs which require
an extra clock cycle between sending the address and reading the data.
