On 32-bit machines, we can't divide 64-bit integers:
drivers/gpu/drm/arm/malidp_crtc.o: In function `malidp_crtc_atomic_check':
malidp_crtc.c:(.text.malidp_crtc_atomic_check+0x3c0): undefined reference to `__aeabi_uldivmod'
malidp_crtc.c:(.text.malidp_crtc_atomic_check+0x3dc): undefined reference to `__aeabi_uldivmod'
This calls the div_u64 function explicitly instead.

When downscaling, mclk needs to be sufficiently higher than pxlclk in
order to be able to fetch the higher-resolution data and produce output
pixels. When not scaling, or when upscaling, mclk can be equal to
pxlclk. Since the driver doesn't control mclk, just ensure that the
requirement is satisfied with the current clock rate.

Enable the scaling engine for upscaling a single plane using the polyphase
scaler. No image enhancement support or downscaling yet*, and composition
result scaling is not implemented.
* Downscaling a plane requires mclk > pxlclk.

Add gamma via the DRM GAMMA_LUT/GAMMA_LUT_SIZE CRTC
properties. The expected LUT size is 4096 in order
to produce as accurate a set of segments as possible.
This version uses only the green channel's gamma curve
to set the hardware curve on DP550/650. For the sake of
simplicity, it uses the same table of coefficients for
all 3 curves on DP500.

Driver changes:
- Fix UHD displays on stih407 (Vincent)

Seeing the kunmap_atomic dma_buf_ops share the same name with a macro
in highmem.h, the former can be aliased if any dma-buf user includes
that header.
I'm personally trying to include highmem.h inside scatterlist.h and this
breaks the dma-buf code proper.
Christoph Hellwig suggested [1] renaming it and pushing this patch ASAP.
To maintain consistency I've renamed all four of kmap* and kunmap* to be
map* and unmap*. (Even though only kmap_atomic presently conflicts.)

Only call synchronize_rcu_expedited after unlocking struct_mutex to
avoid deadlock because the workqueues depend on struct_mutex.
>From original patch by Andrea:
synchronize_rcu/synchronize_sched/synchronize_rcu_expedited() will
hang until its own workqueues are run. The i915 gem workqueues will
wait on the struct_mutex to be released. So we cannot wait for a
quiescent state using those rcu primitives while holding the
struct_mutex or it creates a circular lock dependency resulting in
kernel hangs (which is reproducible but goes undetected by lockdep).

i915 is currently doing a full GPU reset at the end of
i915_gem_suspend() followed by GuC suspend in i915_drm_suspend(). This
GPU reset clobbers the GuC, causing the suspend request to then fail,
leaving the GuC in an undefined state. We need to tell the GuC to
suspend before we do the direct intel_gpu_reset().

This helper is supposed to validate or reject the modeline before it
applied by the mode setting. Currently this function has been dropped,
it was previously set to a dummy function that always returned true. For
both cases, this means that userspace can ask for a bad modeline that
will be always accepted.
On some platforms, like Rockchip, the drm dw_hdmi-rockchip variant driver
already implements the atomic_check drm helper, so mode_fixup cannot be
handled and implemented there (as drm_atomic_helper relies on either
atomic_check or mode_fixup).
This commit implements this helper. It only checks that this mode is
correct from the connector point of view.

If a OPP table is defined for the GPU device in the device tree use
that in lieu of the downstream style GPU frequency table. If we do
use the downstream table convert it to a OPP table so that we can
take advantage of the OPP lookup facilities later.

Some A3XX and A4XX GPU targets required that the GPU clock be
programmed to a non zero value when it was disabled so
27Mhz was chosen as the "invalid" frequency.
Even though newer targets do not have the same clock restrictions
we still write 27Mhz on clock disable and expect the clock subsystem
to round down to zero.
For unknown reasons even though the slow clock speed is always
27Mhz and it isn't actually a functional level the legacy device tree
frequency tables always defined it and then did gymnastics to work
around it.
Instead of playing the same silly games just hard code the "slow" clock
speed in the code as 27MHz and save ourselves a bit of infrastructure.

There are reasons for a memory object to outlive the file descriptor
that created it and so the address space that a buffer object is
attached to must also outlive the file descriptor. Reference count
the address space so that it can remain viable until all the objects
have released their addresses.

We should be detaching the MMU before destroying the address
space. To do this cleanly, the detach has to happen in
adreno_gpu_cleanup() because it needs access to structs
in adreno_gpu.c. Plus it is better symmetry to have
the attach and detach at the same code level.

3D mux is a small block placed after the DSPPs in MDP5. It can merge
2 LM/DSPP outputs and feed it to a single interface.
Enable 3D Mux if our mdp5_pipeline has 2 active LMs. This check
will need to be made more specific later when we add Dual DSI
support with source split enabled. In that use case, each LM feeds to a
separae INTF, so the 3D mux isn't needed.

Assigning LMs dynamically to CRTCs results in REG_MDP5_CTL_LAYER_REGs
and REG_MDP5_CTL_LAYER_EXT_REGs maintaining old values for a LM that
isn't used by our CTL instance anymore.
Clear the ctl's CTL_LAYER_REG and CTL_LAYER_EXT_REGs for all LM
instances. The ones that need to be configured are configured later
in this func.

Dynamically assign a right mixer to mdp5_crtc_state in the CRTC's
atomic_check path. Assigning the right mixer has some constraints,
i.e, only a few LMs can be paired together. Update mdp5_mixer_assign
to handle these constraints.
Firstly, we need to identify whether we need a right mixer or not.
At the moment, there are 2 scenarios where a right mixer might be
needed:
- If any of the planes connected to this CRTC is too wide (i.e, is
comprised of 2 hwpipes).
- If the CRTC's mode itself is too wide (i.e, a 4K mode on HDMI).
We implement both these checks in the mdp5_crtc_atomic_check(), and
pass 'need_right_mixer' to mdp5_setup_pipeline.
If a CRTC is already assigned a single mixer, and a new atomic commit
brings in a drm_plane that needs 2 hwpipes, we can successfully commit
this mode without requiring a full modeset, provided that we still use
the previously assigned mixer as the left mixer. If such an assignment
isn't possible, we'd need to do a full modeset. This scenario has been
ignored for now.
The mixer assignment code is a bit messy, considering we have at most
4 LM instances in hardware. This can probably be re-visited later with
simplified logic.

If a CRTC comprises of 2 LMs, it is mandatory to enable border out
and assign it to the base stage.
We had to enable border out also when the base plane wasn't fullscreen.
Club these checks and put them in a separate function called
get_start_stage() that returns the starting stage for assigning planes.

In order to enable Source Split in HW, we need to add/modify
a few LM register configurations:
- Configure the LM width to be half the mode width, so that
each LM manages one half of the scanout.
- Tell the 'right' LM that it is configured to be the 'right'
LM in source split mode.
- Since we now have 2 places where REG_MDP5_LM_BLEND_COLOR_OUT is
configured, do a read-update-store for the register instead of
directly writing a value to it.

Now that we have a right hwpipe in mdp5_plane_state, configure it
mdp5_plane_mode_set(). The only parameters that vary between the
left and right hwpipes are the src_w, src_img_w, src_x and crtc_x
as we just even chop the fb into left and right halves.
Add a mdp5_plane_right_pipe() which will be used by the crtc code
to set up LM stages.

If the drm_plane has a source width that's greater than the max width
supported by a SSPP (2560 pixels on 8x96), then we assign a 'r_hwpipe'
to it in mdp5_plane_atomic_check().
TODO: There are a few scenarios where the hwpipe assignments aren't
recommended by HW. For example, an assignment which results in a
drm_plane to of two different types of hwpipes (say RGB0 on left
and DMA1 on right) is not recommended.
Also, hwpipes have a priority mapping, where the higher priority pipe
needs to be staged on left LM, and the lower priority needs to be
staged on the right LM. For example, the priority order for VIG pipes
in decreasing order of priority is VIG0, VIG1, VIG2, and VIG3. So, VIG0
on left and VIG1 on right is a correct configuration, but VIG1 on left
and VIG0 on right isn't. These scenarios are ignored for now for the
sake of simplicity.
