Replace the use of drm_debugfs_create_files() with the new
drm_debugfs_add_files() function, which center the debugfs files
management on the drm_device instead of drm_minor. Moreover, remove the
debugfs_init hook and add the debugfs files directly on hdlcd_drm_bind(),
before drm_dev_register().

drm_mode_config_init() simply calls drmm_mode_config_init(), hence
cleanup is automatically handled through registering
drm_mode_config_cleanup() with drmm_add_action_or_reset().
While at it, get rid of the deprecated drm_mode_config_init() and
replace it with drmm_mode_config_init() directly.

The field paddr of struct drm_gem_dma_object holds a DMA address, which
might actually be a physical address. However, depending on the platform,
it can also be a bus address or a virtual address managed by an IOMMU.
Hence, rename the field to dma_addr, which is more applicable.
In order to do this renaming the following coccinelle script was used:
```

struct drm_gem_dma_object *gem;

Rename "GEM CMA" helpers to "GEM DMA" helpers - considering the
hierarchy of APIs (mm/cma -> dma -> gem dma) calling them "GEM
DMA" seems to be more applicable.
Besides that, commit e57924d4ae80 ("drm/doc: Task to rename CMA helpers")
requests to rename the CMA helpers and implies that people seem to be
confused about the naming.
In order to do this renaming the following script was used:
```
#!/bin/bash
DIRS="drivers/gpu include/drm Documentation/gpu"
REGEX_SYM_UPPER="[0-9A-Z_\-]"
REGEX_SYM_LOWER="[0-9a-z_\-]"
REGEX_GREP_UPPER="(${REGEX_SYM_UPPER}*)(GEM)_CMA_(${REGEX_SYM_UPPER}*)"
REGEX_GREP_LOWER="(${REGEX_SYM_LOWER}*)(gem)_cma_(${REGEX_SYM_LOWER}*)"
REGEX_SED_UPPER="s/${REGEX_GREP_UPPER}/\1\2_DMA_\3/g"
REGEX_SED_LOWER="s/${REGEX_GREP_LOWER}/\1\2_dma_\3/g"
# Find all upper case 'CMA' symbols and replace them with 'DMA'.
for ff in $(grep -REHl "${REGEX_GREP_UPPER}" $DIRS)
do
sed -i -E "$REGEX_SED_UPPER" $ff
done
# Find all lower case 'cma' symbols and replace them with 'dma'.
for ff in $(grep -REHl "${REGEX_GREP_LOWER}" $DIRS)
do
sed -i -E "$REGEX_SED_LOWER" $ff
done
# Replace all occurrences of 'CMA' / 'cma' in comments and
# documentation files with 'DMA' / 'dma'.
for ff in $(grep -RiHl " cma " $DIRS)
do
sed -i -E "s/ cma / dma /g" $ff
sed -i -E "s/ CMA / DMA /g" $ff
done
# Rename all 'cma_obj's to 'dma_obj'.
for ff in $(grep -RiHl "cma_obj" $DIRS)
do
sed -i -E "s/cma_obj/dma_obj/g" $ff
done
```
Only a few more manual modifications were needed, e.g. reverting the
following modifications in some DRM Kconfig files
- select CMA if HAVE_DMA_CONTIGUOUS
+ select DMA if HAVE_DMA_CONTIGUOUS
as well as manually picking the occurrences of 'CMA'/'cma' in comments and
documentation which relate to "GEM CMA", but not "FB CMA".
Also drivers/gpu/drm/Makefile was fixed up manually after renaming
drm_gem_cma_helper.c to drm_gem_dma_helper.c.
This patch is compile-time tested building a x86_64 kernel with
`make allyesconfig && make drivers/gpu/drm`.

Komeda driver relies on the generic DRM atomic helper functions to handle
commits. It only implements an atomic_commit_tail hook for the
mode_config_helper_funcs and even that one is pretty close to the generic
implementation with the exception of additional dma_fence signalling.
What the generic helper framework doesn't do is waiting for the actual
hardware to signal that the commit parameters have been written into the
appropriate registers. As we signal CRTC events only on the irq handlers,
we need to flush the configuration and wait for the hardware to respond.
Add the Komeda specific implementation for atomic_commit_hw_done() that
flushes and waits for flip done before calling drm_atomic_helper_commit_hw_done().
The fix was prompted by a patch from Carsten Haitzler where he was trying to
solve the same issue but in a different way that I think can lead to wrong
event signaling to userspace.

If something has already set up the DPU before the komeda driver comes
up, it will fail to init because it was just writing to the SRST bit in
the GCU control register and ignoring others. This resulted in TBU
bringup stalling and init failing. By writing completely we also set the
mode back to 0 (inactive) too and thus TBU bringup works.

The komeda driver doesn't come up with a visible text (FB) mode VT by

Since we no longer need to conform to the structure of the various DRM
IRQ callbacks, we can streamline the code by consolidating the piecemeal
functions and passing around our private data structure directly. We're
also a platform device so should never see IRQ_NOTCONNECTED either.
Furthermore we can also get rid of all the unnecesary read-modify-write
operations, since on install we know we cleared the whole interrupt mask
before enabling the debug IRQs, and thus on uninstall we're always
clearing everything as well.

The Arm Juno board EDK2 port has provided an EFI GOP display via HDLCD0
for some time now, which works nicely as an early framebuffer. However,
once the HDLCD driver probes and takes over the hardware, it should
take over the logical framebuffer as well, otherwise the now-defunct GOP
device hangs about and virtual console output inevitably disappears into
the wrong place most of the time.
We'll do this after binding the HDMI encoder, since that's the most
likely thing to fail, and the EFI console is still better than nothing
when that happens. However, the two HDLCD controllers on Juno are
independent, and many users will still be using older firmware without
any display support, so we'll only bother if we find that the HDLCD
we're probing is already enabled. And if it is, then we'll also stop it,
since otherwise the display can end up shifted if it's still scanning
out while the rest of the registers are subsequently reconfigured.

Clients of drm_writeback_connector_init() initialize the
possible_crtcs and then invoke the call to this API.
To simplify things, allow passing possible_crtcs as a parameter
to drm_writeback_connector_init() and make changes to the
other drm drivers to make them compatible with this change.
changes in v2:
- split the changes according to their functionality
changes in v3:
- allow passing possible_crtcs for existing users of
drm_writeback_connector_init()
- squash the vendor changes into the same commit so
that each patch in the series can compile individually
changes in v4:
- keep only changes related to possible_crtcs
- add line breaks after ARRAY_SIZE
- stop using temporary variables for possible_crtcs
changes in v5:
- None
changes in v6:
- None
changes in v7:
- wrap long lines to match the coding style of existing drivers
- Fix indentation and remove parenthesis where not needed
- use u32 instead of uint32_t for possible_crtcs

If drm_universal_plane_init() fails early we jump to the common cleanup code
that calls komeda_plane_destroy() which in turn could access the uninitalised
drm_plane and crash. Return early if an error is detected without going through

In komeda_plane_add(), komeda_get_layer_fourcc_list() is assigned to
formats and used in drm_universal_plane_init().
drm_universal_plane_init() passes formats to
__drm_universal_plane_init(). __drm_universal_plane_init() further
passes formats to memcpy() as src parameter, which could lead to an
undefined behavior bug on failure of komeda_get_layer_fourcc_list().
Fix this bug by adding a check of formats.
This bug was found by a static analyzer. The analysis employs
differential checking to identify inconsistent security operations
(e.g., checks or kfrees) between two code paths and confirms that the
inconsistent operations are not recovered in the current function or
the callers, so they constitute bugs.
Note that, as a bug found by static analysis, it can be a false
positive or hard to trigger. Multiple researchers have cross-reviewed
the bug.
Builds with CONFIG_DRM_KOMEDA=m show no new warnings,
and our static analyzer no longer warns about this code.

The komeda KMS driver will call drm_plane_create_color_properties() with
a default encoding and range values of BT601 and Limited Range,
respectively.
Since the initial value wasn't carried over in the state, the driver had
to set it again in komeda_plane_reset(). However, the helpers have been
adjusted to set it properly at reset, so this is not needed anymore.

YCrCb. Let's rename it to match.

Replace module_platform_driver() with drm_module_platform_driver(). The
DRM macro respects drm_firmware_drivers_only() and fails if the flag has
been set.

Link drm_fb_cma_helper.o into drm_cma_helper.ko if CONFIG_DRM_KMS_HELPER
has been set. Remove CONFIG_DRM_KMS_CMA_HELPER config option. Selecting
KMS helpers and CMA will now automatically enable CMA KMS helpers.
Some drivers' Kconfig files did not correctly select KMS or CMA helpers.
Fix this as part of the change.
