ae2175641a drm/amd/display: removed unnecessary check when dpp clock increasing
[Why]
When switching single pipe to split pipe, the bandwidth check is just
for first pipe.  The 2nd pipe with abnormal(or zero) dpp clock when pipe
ready and unlock leads the garbage on display.

[How]
Removed external increasing dpp clock check, the internal function
already loops all of pipes to check whether update dpp clock.

f8e792dc5c drm/amd/display: New path for enabling DPG
[WHY]
We want to make enabling test pattern a part of the stream update code
path. This change is the first step towards that goal.

fd1c85d3ac drm/amd/display: Unblank hubp based on plane visibility
[WHY]
DCN10 uses plane visibility to determine when to unblank HUBP; there is
no reason DCN20+ should not do the same.

[HOW]
In addition to changing the check in HWSEQ, we must change
is_pipe_tree_visible so that it checks ODM pipe topologies as well as
MPC. Since we're now checking both ODM and MPC topologies, the helper
function names have been changed to reference "parent" and "child"
instead of "top" and "bottom".

33fd9cb8a2 drm/amd/display: NULL pointer hang
[Why]
In dc_link_dp_set_test_pattern, we assume all pipes have a stream, which
can cause null pointer dereference.

[How]
Add a null pointer check before accessing stream.

1dbb6c8fa6 drm/amd/display: tweak the kerneldoc for active_vblank_irq_count
Commit 71338cb4a7c2 ("drm/amd/display: enable idle optimizations for linux
(MALL stutter)") adds active_vblank_irq_count to amdgpu_display_manager
in ./drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h.

The kerneldoc is incorrectly formatted, and make htmldocs warns:

  ./drivers/gpu/drm/amd/display/amdgpu_dm/amdgpu_dm.h:
    340: warning: Incorrect use of kernel-doc format:          * @active_vblank_irq_count
    379: warning: Function parameter or member 'active_vblank_irq_count' not described in 'amdgpu_display_manager'

Tweak the kerneldoc for active_vblank_irq_count.

18589d74f4 drm-misc-next for v5.12:
UAPI Changes:
 - Not necessarily one, but we document that userspace needs to force probe connectors.
 
 Cross-subsystem Changes:
 - Require FB_ATY_CT for aty on sparc64.
 - video: Fix documentation, and a few compiler warnings.
 - Add devicetree bindings for DP connectors.
 - dma-buf: Update kernel-doc, and add might_lock for resv objects in begin/end_cpu_access.
 
 Core Changes:
 - ttm: Warn when releasing a pinned bo.
 - ttm: Cleanup bo size handling.
 - cma-helper: Remove prime infix, and implement mmap as GEM CMA functions.
 - Split drm_prime_sg_to_page_addr_arrays into 2 functions.
 - Add a new api to install irq using devm.
 - Update panel kerneldoc to inline style.
 - Add DP support to drm/bridge.
 - Assorted small fixes to ttm, fb-helper, scheduler.
 - Add atomic_commit_setup function callback.
 - Automatically use the atomic gamma_set, instead of forcing drivers to declare the default atomic version.
 - Allow using degamma for legacy gamma if gamma is not available.
 - Clarify that primary/cursor planes are not tied to 1 crtc (depending on possible_crtcs).
 - ttm: Cleanup the lru handler.
 
 Driver Changes:
 - Add pm support to ingenic.
 - Assorted small fixes in radeon, via, rockchip, omap2fb, kmb, gma500, nouveau, virtio, hisilicon, ingenic, s6e63m0 panel, ast, udlfb.
 - Add BOE NV110WTM-N61, ys57pss36bh5gq, Khadas TS050 panels.

 - Cleanup compiler and docbook warnings in a lot of fbdev devices.
 - Use the drmm_vram_helper in hisilicon.
 - Add support for BCM2711 DSI1 in vc4.
 - Add support for 8-bit delta RGB panels to ingenic.
 - Add documentation on how to test vkms.
 - Convert vc4 to atomic helpers.
 - Use degamma instead of gamma table in omap, to add support for CTM and color encoding/range properties.
 - Rework omap DSI code, and merge all omapdrm modules now that the last omap panel is now a drm panel.
 - More refactoring of omap dsi code.
 - Enable 10/12 bpc outputs in vc4.

- Add a new api to install irq using devm.
- Update panel kerneldoc to inline style.
- Add DP support to drm/bridge.
- Assorted small fixes to ttm, fb-helper, scheduler.
- Add atomic_commit_setup function callback.
- Automatically use the atomic gamma_set, instead of forcing drivers to declare the default atomic version.

- Add support for BCM2711 DSI1 in vc4.
- Add support for 8-bit delta RGB panels to ingenic.
- Add documentation on how to test vkms.
- Convert vc4 to atomic helpers.
- Use degamma instead of gamma table in omap, to add support for CTM and color encoding/range properties.
- Rework omap DSI code, and merge all omapdrm modules now that the last omap panel is now a drm panel.
- More refactoring of omap dsi code.
- Enable 10/12 bpc outputs in vc4.

This reverts commit a135a1b4c4db1f3b8cbed9676a40ede39feb3362.

This leads to blank screens on some boards after replugging a
display.  Revert until we understand the root cause and can
fix both the leak and the blank screen after replug.

88d5cb2517 drm/amdgpu/display: drop DCN support for aarch64
From Ard:

"Simply disabling -mgeneral-regs-only left and right is risky, given that
the standard AArch64 ABI permits the use of FP/SIMD registers anywhere,
and GCC is known to use SIMD registers for spilling, and may invent
other uses of the FP/SIMD register file that have nothing to do with the
floating point code in question. Note that putting kernel_neon_begin()
and kernel_neon_end() around the code that does use FP is not sufficient
here, the problem is in all the other code that may be emitted with
references to SIMD registers in it.

So the only way to do this properly is to put all floating point code in
a separate compilation unit, and only compile that unit with
-mgeneral-regs-only."

Disable support until the code can be properly refactored to support this
properly on aarch64.

4b6b7437b1 drm/amd/display: Enable fp16 also on DCE-8/10/11.
The hw supports fp16, this is not only useful for HDR,
but also for standard dynamic range displays, because
it allows to get more precise color reproduction with
about 11 - 12 bpc linear precision in the unorm range
0.0 - 1.0.

Working fp16 scanout+display (and HDR over HDMI) was
verified on a DCE-8 asic, so i assume that the more
recent DCE-10/11 will work equally well, now that
format-specific plane scaling constraints are properly
enforced, e.g., the inability of fp16 to scale on older
hw like DCE-8 to DCE-11.

6300b3bd9d drm/amd/display: Check plane scaling against format specific hw plane caps.
This takes hw constraints specific to pixel formats into account,
e.g., the inability of older hw to scale fp16 format framebuffers.

It should now allow safely to enable fp16 formats also on DCE-8,
DCE-10, DCE-11.0

71338cb4a7 drm/amd/display: enable idle optimizations for linux (MALL stutter)
[Why]
We can only use this feature when the display is idle. When active vblank
irq count is 0 we know all the displays are idle.

[How]
-Add a active vblank irq counter
-Update the counter when we enable/disable vblank irq
-if vblank irq count is 0 we can consider mall stutter

61d791365b drm/amd/display: avoid uninitialized variable warning
clang (quite rightly) complains fairly loudly about the newly added
mpc1_get_mpc_out_mux() function returning an uninitialized value if the
'opp_id' checks don't pass.

This may not happen in practice, but the code really shouldn't return
garbage if the sanity checks don't pass.

So just initialize 'val' to zero to avoid the issue.
