Convert the module to be property provider agnostic and allow
it to be used on non-OF platforms.

65a828bab1 gpiolib: use a mutex to protect the list of GPIO devices
The global list of GPIO devices is never modified or accessed from
atomic context so it's fine to protect it using a mutex. Add a new
global lock dedicated to the gpio_devices list and use it whenever
accessing or modifying it.

f95fd4ac15 gpiolib: rename static functions that are called with the lock taken
Rename two functions that read or modify the global GPIO device list but
don't take the lock themselves (and need to be called with it already
acquired). Use the _unlocked() suffix which seems to be used quite
consistently across the kernel despite there also existing the _locked()
suffix for the same purpose.

9a9429b9ce gpio: ixp4xx: Handle clock output on pin 14 and 15
This makes it possible to provide basic clock output on pins
14 and 15. The clocks are typically used by random electronics,
not modeled in the device tree, so they just need to be provided
on request.

In order to not disturb old systems that require that the
hardware defaults are kept in the clock setting bits, we only
manipulate these if either device tree property is present.
Once we know a device needs one of the clocks we can set it
in the device tree.

2c40c1c6ad USB/Thunderbolt changes for 6.7-rc1
Here is the "big" set of USB and Thunderbolt changes for 6.7-rc1.
 Nothing really major in here, just lots of constant development for new
 hardware.  Included in here are:
   - Thunderbolt (i.e. USB4) fixes for reported issues and support for
     new hardware types and devices
   - USB typec additions of new drivers and cleanups for some existing
     ones
   - xhci cleanups and expanded tracing support and some platform
     specific updates
   - USB "La Jolla Cove Adapter (LJCA)" support added, and the gpio, spi,
     and i2c drivers for that type of device (all acked by the respective
     subsystem maintainers.)
   - lots of USB gadget driver updates and cleanups
   - new USB dwc3 platforms supported, as well as other dwc3 fixes and
     cleanups
   - USB chipidea driver updates
   - other smaller driver cleanups and additions, full details in the
     shortlog
 
 All of these have been in the linux-next tree for a while with no
 reported problems, EXCEPT for some merge conflicts that you will run
 into in your tree.  2 of them are in device-tree files, which will be
 trivial to resolve (accept both sides), and the last in the
 drivers/gpio/gpio-ljca.c file, in the remove callback, resolution should
 be pretty trivial (take the version in this branch), see here:
 	https://lore.kernel.org/all/20231016134159.11d8f849@canb.auug.org.au/
 for details, or I can provide a resolved merge point if needed.

 - improve the ignore_interrupt functionality in GPIO ACPI
 - correct notifier return codes in gpiolib-of
 - unexport gpiod_set_transitory() as it's unused outside of core GPIO code
 - while there are still external users accessing struct gpio_chip, let's
   make gpiochip_get_desc() public so that they at least use the preferred
   helper
 - improve locking for lookup tables
 - annotate struct linereq with __counted_by
 - improve GPIOLIB docs
 - add an OF quirk for LED trigger sources

   i2c-mux-gpio, hte-tegra194, gpio-sim
 - use the recommended pattern for autofree variables in gpio-sim
 - add support for more models to gpio-loongson
 - use a notifier chain to notify other blocks about interrupts in
   gpio-eic-sprd instead of looking up GPIO devices on every interrupt

Merge tag 'gpio-updates-for-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/brgl/linux

Pull gpio updates from Bartosz Golaszewski:
 "We don't have any new drivers. The loongson driver is getting extended
  with support for new models. There's a big refactor of gpio-pca953x
  and many small improvements to others.

  The GPIO code in the kernel has acquired a lot of cruft over the years
  as well as many abusers of the API across the kernel tree. This
  release cycle we have started a major cleanup and improvement effort
  that will most likely span several releases. We have started by
  converting external users of struct gpio_chip to accessing the wrapper
  around it - struct gpio_device. This is because the latter is
  reference counted while the former is removed when the provider is
  unbound. We also removed several instances of drivers accessing
  private GPIOLIB structures and including the private header from
  drivers/gpio/.

  To that end you'll see several commits aimed at different subsystems
  (acked by relevant maintainers) as well as two merges from the
  x86/platform tree.

  We'll then rework the locking in GPIOLIB which currently uses a big
  spinlock for many different things and could use becoming more
  fine-grained, especially as it doesn't even get the locking right.
  We'll also use SRCU for protecting the gpio_chip pointer against
  in-kernel hot-unplug crashes similar to what we saw triggered from
  user-space and fixed with semaphores in gpiolib-cdev. The core GPIOLIB
  is still vulnerable to these use-cases. I'm just mentioning the plans
  here, this is not part of this PR.

  You'll see some new instances of using __free(). We've added a
  gpio_device_put cleanup helper similar to the put_device one
  introduced by Peter Zijlstra and used it according to the preferred
  pattern except where it didn't make sense.

  GPIOLIB core:
   - provide interfaces allowing users to retrieve, manage and query the
     reference counted GPIO device instead of accessing the private
     gpio_chip structure
   - replace gpiochip_find() with gpio_device_find()

384461abca pwm: Manage owner assignment implicitly for drivers
Instead of requiring each driver to care for assigning the owner member
of struct pwm_ops, handle that implicitly using a macro. Note that the
owner member has to be moved to struct pwm_chip, as the ops structure
usually lives in read-only memory and so cannot be modified.

The upside is that new low level drivers cannot forget the assignment and
save one line each. The pwm-crc driver didn't assign .owner, that's not
a problem in practice though as the driver cannot be compiled as a
module.
