"mali-dp driver changes for drm-next, includes the driver implementation
for writeback, improvements for power management handling in the driver
and a debugfs entry for reporting possible internal errors. Please pull
at your earliest convenience.
Boris Brezillon is also interested in this pull as he is going to change
slightly the parameter for the writeback connector's atomic_commit() and
he needs to fix the mali-dp driver in his series."

malidp_pm_suspend_late checks if the runtime status is not suspended
and if so, invokes malidp_runtime_pm_suspend which disables the
display engine/core interrupts and the clocks. It sets the runtime status
as suspended.
The difference between suspend() and suspend_late() is as follows:-
1. suspend() makes the device quiescent. In our case, we invoke the DRM
helper which disables the CRTC. This would have invoked runtime pm
suspend but the system suspend process disables runtime pm.
2. suspend_late() It continues the suspend operations of the drm device
which was started by suspend(). In our case, it performs the same functionality
as runtime_suspend().
The complimentary functions are resume() and resume_early(). In the case of
resume_early(), we invoke malidp_runtime_pm_resume() which enables the clocks
and the interrupts. It sets the runtime status as active. If the device was
in runtime suspend mode before system suspend was called, pm_runtime_work()
will put the device back in runtime suspended mode( after the complete system
has been resumed).

One needs to store the value of the OUTPUT_DEPTH that one has parsed from
device tree, so that it can be restored on system resume. This value is
set in the modeset function as this gets reset when the system suspends.

Display and scaling engine interrupts need to be disabled when the
runtime pm invokes malidp_runtime_pm_suspend(). Conversely, they
need to be enabled in malidp_runtime_pm_resume().

Malidp uses two interrupts ie 1. se_irq - used for memory writeback.
and 2. de_irq - used for display output.
Extract the hardware initialization part from malidp interrupt registration
ie (malidp_de_irq_init()/ malidp_se_irq_init()) into a separate function
(ie malidp_de_irq_hw_init()/malidp_se_irq_hw_init())
which will be later invoked from runtime_pm_resume function when it needs
to re-enable the interrupts.

Malidp uses two interrupts ie 1. se_irq - used for memory writeback.
and 2. de_irq - used for display output.
'struct drm_device' is being replaced with 'struct malidp_hw_device'
as the function argument. The reason being the dependency of
malidp_de_irq_fini on 'struct drm_device' needs to be removed so as to
enable it to call from functions which receives 'struct malidp_hw_device'
as argument. Furthermore, there is no way to retrieve 'struct drm_device'
from 'struct malidp_hw_device'.

Status register contains a lot of bits for reporting internal errors
inside Mali DP. Currently, we just silently ignore all of the errors,
that doesn't help when we are investigating different bugs, especially
on the FPGA models which have a lot of constraints, so we could easily
end up in AXI or underrun errors.
Add a new file called debug that contains an aggregate of the
errors reported by the Mali DP hardware.
E.g:
[root@alarm ~]# cat /sys/kernel/debug/dri/1/debug
[DE] num_errors : 167
[DE] last_error_status : 0x00000001
[DE] last_error_vblank : 385
[SE] num_errors : 3
[SE] last_error_status : 0x00e23001
[SE] last_error_vblank : 201
Changes since v2:
- Add lock to protect the errors stats.
- Add possibility to reset the error stats by writing anything to the
debug file.

Mali DP500 operates in continuous writeback mode (writes frame content
until stopped) and it needs special handling in order to behave like
a one-shot writeback engine. The original state machine added for DP500
was a bit fragile, as it did not handle correctly cases where a new
atomic commit was in progress when the SE IRQ happens and it would
commit some partial updates.
Improve the handling by adding a parameter to the set_config_valid()
function to clear the config valid bit in hardware before starting a
new commit and by introducing a MW_RESTART state in the writeback
state machine to cater for the case where a new writeback commit
gets submitted while the last one is still being active.

Mali DP500 behaves differently from the rest of the Mali DP IP,
in that it does not have a one-shot mode and keeps writing the
content of the current frame to the provided memory area until
stopped. As a way of emulating the one-shot behaviour, we are
going to use the CVAL interrupt that is being raised at the
start of each frame, during prefetch phase, to act as End-of-Write
signal, but with a twist: we are going to disable the memory
write engine right after we're notified that it has been enabled,
using the knowledge that the bit controlling the enabling will
only be acted upon on the next vblank/prefetch.
CVAL interrupt will fire durint the next prefetch phase every time
the global CVAL bit gets set, so we need a state byte to track
the memory write enabling. We also need to pay attention during the
disabling of the memory write engine as that requires the CVAL bit
to be set in the control register, but we don't want to do that
during an atomic commit, as it will write into the hardware a partial
state.

In commits:

1931529448bc ("drm: Add acquire ctx parameter to ->plane_disable")
a pointer to a drm_modeset_acquire_ctx structure was added as an
argument to the method prototypes. The transitional helpers are
supposed to be directly plugged in as implementations of these
methods, but doing so generates a warning. Add the missing

A number of buggy users were added for drm_plane_helper_disable()

encoder/connector
One needs to ensure that the crtcs are shutdown so that the
drm_crtc_state->connector_mask reflects that no connectors
are currently active. Further, it reduces the reference
count for each connector. This ensures that the connectors
and encoders can be cleanly removed either when _unbind
is called for the corresponding drivers or by
drm_mode_config_cleanup().
We need drm_atomic_helper_shutdown() to be called before
component_unbind_all() otherwise the connectors attached to the
component device will have the wrong reference count value and will not
be cleanly removed.

Internally Mali DP uses an RGB pipeline so video layers that support
YUV input buffers need to convert the input data to RGB. The YUV
buffers can have various encodings and this patch introduces support
for BT.601, BT.709 and BT.2020 encodings, both limited and full ranges.
This patch adds support for specifying the color encoding of the
input buffers for the planes that are backed by the video layers
and programs the YUV2RGB coefficients into hardware based on the
selected encoding.

The top-level error handler calls drm_mode_config_cleanup() which will
destroy all planes. There's no need to destroy them manually in lower
error handlers.
As plane cleanup is now handled entirely by drm_mode_config_cleanup(),
we must ensure that the plane .destroy() handler frees allocated memory
for the plane object that was freed by malidp_de_planes_destroy(). Do so
by replacing the call to devm_kfree() in the .destroy() handler by
kfree(). devm_kfree() is currently a no-op as the plane memory is
allocated with kzalloc(), not devm_kzalloc().

Mali DP hardware has a 'go' bit (config_valid) for making the new scene
parameters active at the next page flip. The problem with the current
code is that the driver first sets this bit and then proceeds to wait
for confirmation from the hardware that the configuration has been
updated before arming the vblank event. As config_valid is actually
asserted by the hardware after the vblank event, during the prefetch
phase, when we get to arming the vblank event we are going to send it
at the next vblank, in effect halving the vblank rate from the userspace
perspective.
Fix it by sending the userspace event from the IRQ handler, when we
handle the config_valid interrupt, which syncs with the time when the
hardware is active with the new parameters.

Mali DP hardware needs pitch line sizes aligned to the bus burst
size for reads, so take that into consideration when allocating dumb

The malidp_hw_device structure that the driver uses to handle the
differences between versions of the IP contains both non-changeable
data and fields that get updated at probe time. Previously we were
copying the read-only part into allocated memory, but that can be
completely avoided by splitting the structure into a read-only part
and keeping the runtime modifiable fields into the old structure.

Use drm_*_get() and drm_*_put() helpers instead of drm_*_reference()
and drm_*_unreference() helpers.
drm_*_reference() and drm_*_unreference() functions are just
compatibility alias for drm_*_get() and drm_*_put() and should not be
used by new code. So convert all users of compatibility functions to
use the new APIs.

drm_plane_helper_check_update() isn't a transitional helper, so let's
rename it to drm_atomic_helper_check_plane_state() and move it into
drm_atomic_helper.c.

drm_plane_helper_check_state()
drm_plane_helper_check_state() is supposed to do things the atomic way,
so it should not be inspecting crtc->enabled. Rather we should be
looking at crtc_state->enable.
We have a slight complication due to drm_plane_helper_check_update()
reusing drm_plane_helper_check_state() for non-atomic drivers. Thus
we'll have to pass the crtc_state in manally and construct a fake
crtc_state in drm_plane_helper_check_update().

There is a new core debugfs file that prints fb/gem info:
<debugfs>/dri/<n>/framebuffer
Use drm_gem_cma_print_info() to provide info to that output instead
of using drm_fb_cma_debugfs_show().
