drm/tilcdc: Fix irq free on unload

[ Upstream commit 38360bf96d816e175bc602c4ee76953cd303b71d ]

The driver only frees the reserved irq if priv->irq_enabled is set to
true. However, the driver mistakenly sets priv->irq_enabled to false,
instead of true, in tilcdc_irq_install(), and thus the driver never
frees the irq, causing issues on loading the driver a second time.

drm: Call drm_atomic_helper_shutdown() at shutdown/remove time for misc drivers

drm: Call drm_atomic_helper_shutdown() at shutdown/remove time for misc drivers

[ Upstream commit 3c4babae3c4a1ae05f8f3f5f3d50c440ead7ca6a ]

Based on grepping through the source code these drivers appear to be
missing a call to drm_atomic_helper_shutdown() at system shutdown time
and at driver remove (or unbind) time. Among other things, this means
that if a panel is in use that it won't be cleanly powered off at
system shutdown time.

The fact that we should call drm_atomic_helper_shutdown() in the case
of OS shutdown/restart and at driver remove (or unbind) time comes
straight out of the kernel doc "driver instance overview" in
drm_drv.c.

A few notes about these fixes:
- I confirmed that these drivers were all DRIVER_MODESET type drivers,
which I believe makes this relevant.
- I confirmed that these drivers were all DRIVER_ATOMIC.
- When adding drm_atomic_helper_shutdown() to the remove/unbind path,
I added it after drm_kms_helper_poll_fini() when the driver had
it. This seemed to be what other drivers did. If
drm_kms_helper_poll_fini() wasn't there I added it straight after
drm_dev_unregister().
- This patch deals with drivers using the component model in similar
ways as the patch ("drm: Call drm_atomic_helper_shutdown() at
shutdown time for misc drivers")
- These fixes rely on the patch ("drm/atomic-helper:
drm_atomic_helper_shutdown(NULL) should be a noop") to simplify
shutdown.

drm: tilcdc: Remove #ifdef guards for PM related functions

Use the DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr() macros to handle
the .suspend/.resume callbacks.

These macros allow the suspend and resume functions to be automatically
dropped by the compiler when CONFIG_SUSPEND is disabled, without having
to use #ifdef guards.

This has the advantage of always compiling these functions in,
independently of any Kconfig option. Thanks to that, bugs and other
regressions are subsequently easier to catch.

drm/gem: rename GEM CMA helpers to GEM DMA helpers

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`.

drm/tilcdc: Convert to Linux IRQ interfaces

Drop the DRM IRQ midlayer in favor of Linux IRQ interfaces. DRM's
IRQ helpers are mostly useful for UMS drivers. Modern KMS drivers
don't benefit from using it.

DRM IRQ callbacks are now being called directly or inlined.

Calls to platform_get_irq() can fail with a negative errno code.
Abort initialization in this case. The DRM IRQ midlayer does not
handle this case correctly.

For most drivers, only the DRM IRQ helpers use irq_enabled from
struct drm_device. Tilcdc also uses irq_enabled to make its error
rollback work correctly. As the field will become legacy, duplicated
the state in the driver's local private structure.

- nouveau, because DRIVER_ATOMIC uapi is still not the default on the
platforms where it's supported (i.e. again driver_feature mangling)
- vc4, again because of driver_feature mangling
- qxl, because the ioctl table is somewhere else and moving that is
maybe a bit too much, hence the num_ioctls assignment prevents a
const driver structure.
- arcpgu, because that is stuck behind a pending tiny-fication series
from me.
- legacy drivers, because legacy requires non-const drm_driver.

Note that for armada I also went ahead and made the ioctl array const.

is way too much).

drm/tilcdc: Use standard drm_atomic_helper_commit

Gives us proper nonblocking support for free, and a pile of other
things. The tilcdc code is simply old enough that it was never
converted over, but was stuck forever with the copypasta from when it
was initially merged.

The riskiest thing with this conversion is maybe that there's an issue
with the vblank handling or vblank event handling, which will upset
the modern commit support in atomic helpers. But from a cursory review
drm_crtc_vblank_on/off is called in the right places, and the event
handling also seems to exist (albeit with much hand-rolling and
probably some races, could perhaps be converted over to
drm_crtc_arm_vblank_event without any real loss).

Motivated by me not having to hand-roll the dma-fence annotations for
this.

v2: Clear out crtc_state->event when we're handling the event, to
avoid upsetting the helpers (reported by Jyri).

v3: Also send out even whent the crtc is getting disabled. Tilcdc looks a
bit like conversion to simple display helpers would work out really
nice.

drm: convert .debugfs_init() hook to return void.

As a result of commit 987d65d01356 (drm: debugfs: make
drm_debugfs_create_files() never fail) and changes to various debugfs
functions in drm/core and across various drivers, there is no need for
the drm_driver.debugfs_init() hook to have a return value. Therefore,
declare it as void.

This also includes refactoring all users of the .debugfs_init() hook to
return void across the subsystem.

v2: include changes to the hook and drivers that use it in one patch to
prevent driver breakage and enable individual successful compilation of
this change.
