d54ee94603 drm/amd/display: Enable backlight support for pre-DCE11 ASICs
Initializing ABM and DMCU modules for dce 80/81/83/100 as in DCE110
Adding constructors and destructors for each module.
Adding register list for DMCU in dce80 as some registers are missing
in dce80 from the basic list. DMCU is never used, so it would not have
any functional impact.

a4056c2a63 drm/amd/display: use HW hdr mult for brightness boost
In MPO scenario when playing SDR clip in HDR desktop mode, Win is
boosting desktop and requests driver to boost MPO. But driver boosting
is currently done in regamma which is stream property and thus shared
between grph and video.

Redesigning the boosting in RV: use CM_HDR_MULT register which was added
for this scenario. It also has the benefit that it can be done in HIRQL.

48527e5296 drm/amdgpu: refactoring mailbox to fix TDR handshake bugs(v2)
this patch actually refactor mailbox implmentations, and
all below changes are needed together to fix all those mailbox
handshake issues exposured by heavey TDR test.

1)refactor all mailbox functions based on byte accessing for mb_control
reason is to avoid touching non-related bits when writing trn/rcv part of
mailbox_control, this way some incorrect INTR sent to hypervisor
side could be avoided, and it fixes couple handshake bug.

2)trans_msg function re-impled: put a invalid
logic before transmitting message to make sure the ACK bit is in
a clear status, otherwise there is chance that ACK asserted already
before transmitting message and lead to fake ACK polling.
(hypervisor side have some tricks to workaround ACK bit being corrupted
by VF FLR which hase an side effects that may make guest side ACK bit
asserted wrongly), and clear TRANS_MSG words after message transferred.

3)for mailbox_flr_work, it is also re-worked: it takes the mutex lock
first if invoked, to block gpu recover's participate too early while
hypervisor side is doing VF FLR. (hypervisor sends FLR_NOTIFY to guest
before doing VF FLR and sentds FLR_COMPLETE after VF FLR done, and
the FLR_NOTIFY will trigger interrupt to guest which lead to
mailbox_flr_work being invoked)

This can avoid the issue that mailbox trans msg being cleared by its VF FLR.

4)for mailbox_rcv_irq IRQ routine, it should only peek msg and schedule
mailbox_flr_work, instead of ACK to hypervisor itself, because FLR_NOTIFY
msg sent from hypervisor side doesn't need VF's ACK (this is because
VF's ACK would lead to hypervisor clear its trans_valid/msg, and this
would cause handshake bug if trans_valid/msg is cleared not due to
correct VF ACK but from a wrong VF ACK like this "FLR_NOTIFY" one)

This fixed handshake bug that sometimes GUEST always couldn't receive
"READY_TO_ACCESS_GPU" msg from hypervisor.

5)seperate polling time limite accordingly:
POLL ACK cost no more than 500ms
POLL MSG cost no more than 12000ms
POLL FLR finish cost no more than 500ms

6) we still need to set adev into in_gpu_reset mode after we received
FLR_NOTIFY from host side, this can prevent innocent app wrongly succesed
to open amdgpu dri device.

FLR_NOFITY is received due to an IDLE hang detected from hypervisor side
which indicating GPU is already die in this VF.

v2:
use MACRO as the offset of mailbox_control register
don't test if NOTIFY_CMPL event in rcv_msg since it won't
recieve that message anymore

1c85f2fa68 drm/rockchip: Don't use spin_lock_irqsave in interrupt context
The rockchip DRM driver is quite careful to disable interrupts
when taking a lock that is also taken in interrupt context,
which is a good thing.

What is a bit over the top is to use spin_lock_irqsave when
already in interrupt context, as you cannot take another
interrupt again, and disabling interrupt is just pure
overhead.

Switching to the non _irqsave version in interrupt context is
more logical, and less heavy handed.

5f9e93fed4 drm/rockchip: Clear all interrupts before requesting the IRQ
Calling request_irq() followed by disable_irq() is usually a bad idea,
specially if the interrupt can be pending, and you're not yet in a
position to handle it.

This is exactly what happens on my kevin system when rebooting in a
second kernel using kexec: Some interrupt is left pending from
the previous kernel, and we take it too early, before disable_irq()
could do anything.

Let's clear the pending interrupts as we initialize the HW, and move
the interrupt request after that point. This ensures that we're in
a sane state when the interrupt is requested.

828f207077 drm: arm: malidp: Use drm_atomic_helper_shutdown() to disable planes on removal
The plane cleanup handler currently calls drm_plane_helper_disable(),
which is a legacy helper function. Replace it with a call to
drm_atomic_helper_shutdown() at removal time.

084ffbd7fd drm: arm: malidp: Don't destroy planes manually in error handlers
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().

d862b2d622 drm/mali-dp: Fix malidp_atomic_commit_hw_done() for event sending.
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.

f0437819ad drm/arm/malidp: Disable pixel alpha blending for colors that do not have alpha
Mali dp needs to disable pixel alpha blending (use layer alpha blending) to
display color formats that do not contain alpha bits per pixel

This patch depends on:

"[PATCH v2 01/19] drm/fourcc: Add a alpha field to drm_format_info"

6cc3a505dc drm: mali-dp: Fix bug on scaling with rotation
In the case, when the user wants to scale and rotate a layer by 90/270
degrees, the scaling engine input dimensions' parameters ie width and
height needs to be swapped with respect to the layer's input dimensions.
This means scaling engine input height should be set to layer's input
width and scaling engine input width should be set to
layer's input height.

e0521c05c1 drm/mali-dp: Don't enable scaling engine for planes that only rotate.
Currently the scaling engine gets enabled for a plane where the input
size differs from the composition size. As rotation is done natively
by the plane's hardware layer, we don't need the scaling engine to be
enabled.

5ed4fdfa58 drm/mali-dp: Align pitch size to be multiple of bus burst read size.
Mali DP hardware needs pitch line sizes aligned to the bus burst
size for reads, so take that into consideration when allocating dumb
buffers. If the layer is rotated then the stride size requirement is
even larger for some hardware versions, so allocate for the worst case
scenario. Update the ->dumb_create() hook to a driver specific function
that sets the correct pitch size.

fcad73b9b1 drm/mali-dp: Rotated planes need a larger pitch size.
Rotated planes need a pitch size that is aligned to 8 bytes
for older DP500 and DP550 and at least 64 bytes for DP650. Replace
the malidp_hw_pitch_valid() function with one that calculates
the correct pitch alignment to take into account rotation.
