Clean up the existing export namespace code along the same lines of
commit 33def8498fdd ("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.

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 char/misc/IIO/whatever driver subsystem updates from Greg KH:
"Here is the 'big and hairy' char/misc/iio and other small driver
subsystem updates for 6.13-rc1.
Loads of things in here, and even a fun merge conflict!
- rust misc driver bindings and other rust changes to make misc

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

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:

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 86f134941a4b ("MAINTAINERS: Add the Microchip LAN966x PCI driver
entry") introduces a trivial merge conflict with commit 7280f01e79cc

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().

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.

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.

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.

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.

Add a quirk similar to eeprom_93xx46 to add an extra clock cycle before
reading data from the EEPROM.
The 93Cx6 family of EEPROMs output a "dummy 0 bit" between the writing
of the op-code/address from the host to the EEPROM and the reading of
the actual data from the EEPROM.
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.
