42bd415bd8 nouveau/gsp/r535: Fix a NULL vs error pointer bug 
The r535_gsp_cmdq_get() function returns error pointers but this code
checks for NULL.  Also we need to propagate the error pointer back to
the callers in r535_gsp_rpc_get().  Returning NULL will lead to a NULL
pointer dereference.

09f12bf9f7 nouveau/gsp/r535: uninitialized variable in r535_gsp_acpi_mux_id() 
The if we hit the "continue" statement on the first iteration through
the loop then "handle_mux" needs to be set to NULL so we continue
looping.

b5bad8c16b nouveau/gsp: move to 535.113.01 
This moves the initial effort to the latest 535 firmware.

The gsp msg structs have changed, and the message passing also.
The wpr also seems to have some struct changes.

This version of the firmware will be what we are stuck on for a while,
until we can refactor the driver and work out a better path forward.

provided by NVIDIA, bringing with it the beginnings of Ada support.

Until it's had more testing and time to bake, support is disabled by
default (except on Ada).  GSP-RM usage can be enabled by passing the
"config=NvGspRm=1" module option.

d79d91026e drm/nouveau/devinit/tu102-: remove attempt at loading PreOS 
From Turing, HW will already have handled this and locked-down the
falcon before we get control.  So this *should* be a no-op.

6b252cf422 drm/nouveau: nvkm/vmm: implement raw ops to manage uvmm 
The new VM_BIND UAPI uses the DRM GPU VA manager to manage the VA space.
Hence, we a need a way to manipulate the MMUs page tables without going
through the internal range allocator implemented by nvkm/vmm.

This patch adds a raw interface for nvkm/vmm to pass the resposibility
for managing the address space and the corresponding map/unmap/sparse
operations to the upper layers.

752a281032 drm/nouveau/i2c: fix number of aux event slots 
This was completely bogus before, using maximum DCB device index rather
than maximum AUX ID to size the buffer that stores event refcounts.

*Pretty* unlikely to have been an actual problem on most configurations,
that is, unless you've got one of the rare boards that have off-chip DP.

There, it'll likely crash.

6c7f27441d Merge tag 'drm-misc-next-2023-07-13' of git://anongit.freedesktop.org/drm/drm-misc into drm-next 
drm-misc-next for v6.6:

UAPI Changes:

 * fbdev:
   * Make fbdev userspace interfaces optional; only leaves the
     framebuffer console active

 * prime:
   * Support dma-buf self-import for all drivers automatically: improves
     support for many userspace compositors

Cross-subsystem Changes:

 * backlight:
   * Fix interaction with fbdev in several drivers

 * base: Convert struct platform.remove to return void; part of a larger,
   tree-wide effort

 * dma-buf: Acquire reservation lock for mmap() in exporters; part
   of an on-going effort to simplify locking around dma-bufs

 * fbdev:
   * Use Linux device instead of fbdev device in many places
   * Use deferred-I/O helper macros in various drivers

 * i2c: Convert struct i2c from .probe_new to .probe; part of a larger,
   tree-wide effort

 * video:
   * Avoid including <linux/screen_info.h>

Core Changes:

 * atomic:
   * Improve logging

 * prime:
   * Remove struct drm_driver.gem_prime_mmap plus driver updates: all
     drivers now implement this callback with drm_gem_prime_mmap()

 * gem:
   * Support execution contexts: provides locking over multiple GEM
     objects

 * ttm:
   * Support init_on_free
   * Swapout fixes

Driver Changes:
