995832b2ce Replace <linux/mod_devicetable.h> by more specific <linux/device-id/*.h> (c files) 
Replace the #include of <linux/mod_devicetable.h> by the more specific
<linux/device-id/*.h> where applicable. For most cases the include
can be dropped completely, only a few drivers need one or two headers
added.

5164f7e7ff drm: Rename struct drm_atomic_state to drm_atomic_commit 
The KMS framework uses two slightly different definitions for the state
concept. For a given object (plane, CRTC, encoder, etc., so
drm_$OBJECT_state), the state is the entire state of that object.
However, at the device level, drm_atomic_state refers to a state update
for a limited number of objects.

Thus, drm_atomic_state isn't the entire device state, but only the full
state of some objects in that device. This has been an endless source of
confusion and thus bugs.

We can rename the drm_atomic_state structure to drm_atomic_commit to
make it less confusing.

This patch was created using:

rg -l drm_atomic_state | \
	xargs sed -i 's/drm_atomic_state/drm_atomic_commit/g; s/drm_atomic_commit_helper/drm_atomic_state_helper/g'
mv drivers/gpu/drm/tests/drm_atomic_state_test.c drivers/gpu/drm/tests/drm_atomic_commit_test.c

bf4afc53b7 Convert 'alloc_obj' family to use the new default GFP_KERNEL argument 
This was done entirely with mindless brute force, using

    git grep -l '\<k[vmz]*alloc_objs*(.*, GFP_KERNEL)' |
        xargs sed -i 's/\(alloc_objs*(.*\), GFP_KERNEL)/\1)/'

to convert the new alloc_obj() users that had a simple GFP_KERNEL
argument to just drop that argument.

Note that due to the extreme simplicity of the scripting, any slightly
more complex cases spread over multiple lines would not be triggered:
they definitely exist, but this covers the vast bulk of the cases, and
the resulting diff is also then easier to check automatically.

For the same reason the 'flex' versions will be done as a separate
conversion.

69050f8d6d treewide: Replace kmalloc with kmalloc_obj for non-scalar types 
This is the result of running the Coccinelle script from
scripts/coccinelle/api/kmalloc_objs.cocci. The script is designed to
avoid scalar types (which need careful case-by-case checking), and
instead replace kmalloc-family calls that allocate struct or union
object instances:

Single allocations:	kmalloc(sizeof(TYPE), ...)
are replaced with:	kmalloc_obj(TYPE, ...)

Array allocations:	kmalloc_array(COUNT, sizeof(TYPE), ...)
are replaced with:	kmalloc_objs(TYPE, COUNT, ...)

Flex array allocations:	kmalloc(struct_size(PTR, FAM, COUNT), ...)
are replaced with:	kmalloc_flex(*PTR, FAM, COUNT, ...)

(where TYPE may also be *VAR)

The resulting allocations no longer return "void *", instead returning
"TYPE *".

Merge tag 'pm-6.20-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/rafael/linux-pm

Pull power management updates from Rafael Wysocki:
 "By the number of commits, cpufreq is the leading party (again) and the
  most visible change there is the removal of the omap-cpufreq driver
  that has not been used for a long time (good riddance). There are also
  quite a few changes in the cppc_cpufreq driver, mostly related to
  fixing its frequency invariance engine in the case when the CPPC
  registers used by it are not in PCC. In addition to that, support for
  AM62L3 is added to the ti-cpufreq driver and the cpufreq-dt-platdev
  list is updated for some platforms. The remaining cpufreq changes are
  assorted fixes and cleanups.

  Next up is cpuidle and the changes there are dominated by intel_idle
  driver updates, mostly related to the new command line facility
  allowing users to adjust the list of C-states used by the driver.
  There are also a few updates of cpuidle governors, including two menu
  governor fixes and some refinements of the teo governor, and a
  MAINTAINERS update adding Christian Loehle as a cpuidle reviewer.
  [Thanks for stepping up Christian!]

  The most significant update related to system suspend and hibernation
  is the one to stop freezing the PM runtime workqueue during system PM
  transitions which allows some deadlocks to be avoided. There is also a
  fix for possible concurrent bit field updates in the core device
  suspend code and a few other minor fixes.

  Apart from the above, several drivers are updated to discard the
  return value of pm_runtime_put() which is going to be converted to a
  void function as soon as everybody stops using its return value, PL4
  support for Ice Lake is added to the Intel RAPL power capping driver,
  and there are assorted cleanups, documentation fixes, and some
  cpupower utility improvements.

  Specifics:

   - Remove the unused omap-cpufreq driver (Andreas Kemnade)

   - Optimize error handling code in cpufreq_boost_trigger_state() and
     make cpufreq_boost_trigger_state() return -EOPNOTSUPP if no policy

75e8635832 drm: Discard pm_runtime_put() return value 
Multiple DRM drivers use the pm_runtime_put() return value for printing
debug or even error messages and all of those messages are at least
somewhat misleading.

Returning an error code from pm_runtime_put() merely means that it has
not queued up a work item to check whether or not the device can be
suspended and there are many perfectly valid situations in which that
can happen, like after writing "on" to the devices' runtime PM "control"
attribute in sysfs for one example.  It also happens when the kernel
has been configured with CONFIG_PM unset.

For this reason, modify all of those drivers to simply discard the
pm_runtime_put() return value which is what they should be doing.

This will facilitate a planned change of the pm_runtime_put() return
type to void in the future.

0709abaf67 drm/imx/ipuv3: Fix dumb-buffer allocation for non-RGB formats 
Align pitch to multiples of 8 pixels for bpp values that do not map
to RGB formats. The call to drm_driver_color_mode_format() fails with
DRM_INVALID_FORMAT in these cases. Fall back to manually computing
the pitch alignment from which drm_mode_size_dumb() can compute the
correct pitch.

Fixes userspace that allocates dumb buffers for YUV formats, where
bpp equals 12. A common example is the IGT kms_getfb test.

3257bd193f drm/imx: parallel-display: convert to devm_drm_bridge_alloc() API 
This is the new API for allocating DRM bridges.

This conversion was missed during the initial conversion of all bridges to
the new API. Thus all kernels with commit 94d50c1a2c ("drm/bridge:
get/put the bridge reference in drm_bridge_attach/detach()") and using this
driver now warn due to drm_bridge_attach() incrementing the refcount, which
is not initialized without using devm_drm_bridge_alloc() for allocation.

To make the conversion simple and straightforward without messing up with
the drmm_simple_encoder_alloc(), move the struct drm_bridge from struct
imx_parallel_display_encoder to struct imx_parallel_display.

Also remove the 'struct imx_parallel_display *pd' from struct
imx_parallel_display_encoder, not needed anymore.

Call drm_mode_size_dumb() to compute dumb-buffer scanline pitch and
buffer size. Align the pitch to a multiple of 8.

Push the current calculation into the only direct caller imx. Imx's
hardware requires the framebuffer width to be aligned to 8. The
driver's current approach is actually incorrect, as it only guarantees
this implicitly and requires bpp to be a multiple of 8 already. A
later commit will fix this problem by aligning the scanline pitch
such that an aligned width still fits into each scanline's memory.

A number of other drivers are build on top of gem-dma helpers and
implement their own dumb-buffer allocation. These drivers invoke
drm_gem_dma_dumb_create_internal(), which is not affected by this

However, one of the main use of that pointer is done in attach to just
call drm_bridge_attach on the next bridge to add it to the bridge list.
While this dereferences the bridge->encoder pointer, it's effectively
the same encoder the bridge was being attached to.

We can make it more explicit by adding the encoder the bridge is
attached to to the list of attach parameters. This also removes the need
to dereference bridge->encoder in most drivers.

26d6fd8191 drm/connector: make mode_valid take a const struct drm_display_mode 
The mode_valid() callbacks of drm_encoder, drm_crtc and drm_bridge
take a const struct drm_display_mode argument. Change the mode_valid
callback of drm_connector to also take a const argument.
