2a7e5f4531 drm/ast: Implement atomic enable/disable for encoders 
The CRTC helpers contain code to enable and disable DisplayPort
connectors. Implement this functionality in the respective connector's
atomic_enable/atomic_disable callbacks. DRM's atomic-modesetting
helpers will call the functions as part of the atomic commit.

2210093478 drm/exynos/vidi: convert to struct drm_edid 
Prefer the struct drm_edid based functions for storing the EDID and
updating the connector.

It would be better if the vidi connection ioctl passed in the EDID size
separately instead of relying on the extension count specified in the
EDID, but that's what we have to rely on.

10b566f21b drm/exynos/vidi: simplify fake edid handling 
Avoid assigning fake_edid_info to ctx->raw_edid. Always keep
ctx->raw_edid either an allocated pointer or NULL. Defer fake_edid_info
handling to .get_modes().

This should be functionally equivalent but slightly easier to follow.

98e05e40e9 Merge tag 'exynos-drm-fixes-for-v6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into exynos-drm-next 
Regression fix
- Fix an regression issue by adding 640x480 fallback mode
  for Exynos HDMI driver.

Bug fix
- Fix a memory leak by ensuring the duplicated EDID is properly freed in the get_modes function.

Code cleanup
- Remove redundant driver owner initialization since platform_driver_register() sets it automatically.

6fb15dcbcf drm/radeon: check bo_va->bo is non-NULL before using it 
The call to radeon_vm_clear_freed might clear bo_va->bo, so
we have to check it before dereferencing it.

0ad4b4a2f6 drm/amd/display: Fix array-index-out-of-bounds in dml2/FCLKChangeSupport 
[Why]
Potential out of bounds access in dml2_calculate_rq_and_dlg_params()
because the value of out_lowest_state_idx used as an index for FCLKChangeSupport
array can be greater than 1.

[How]
Currently dml2 core specifies identical values for all FCLKChangeSupport
elements. Always use index 0 in the condition to avoid out of bounds access.

9ef1548aea drm/amd/display: Fix refresh rate range for some panel 
[Why]
Some of the panels does not have the refresh rate range info
in base EDID and only have the refresh rate range info in
DisplayID block.
It will cause the max/min freesync refresh rate set to 0.

[How]
Try to parse the refresh rate range info from DisplayID if the
max/min refresh rate is 0.

074b3a8867 drm/amd/display: Account for cursor prefetch BW in DML1 mode support 
[Description]
We need to ensure to take into account cursor prefetch BW in
mode support or we may pass ModeQuery but fail an actual flip
which will cause a hang. Flip may fail because the cursor_pre_bw
is populated during mode programming (and mode programming is
never called prior to ModeQuery).

74ad26b36d drm/amd/display: Add refresh rate range check 
[Why]
We only enable the VRR while monitor usable refresh rate range
is greater than 10 Hz.
But we did not check the range in DRM_EDID_FEATURE_CONTINUOUS_FREQ
case.

[How]
Add a refresh rate range check before set the freesync_capable flag
in DRM_EDID_FEATURE_CONTINUOUS_FREQ case.

6b8487cdf9 drm/amd/display: Reset freesync config before update new state 
[Why]
Sometimes the new_crtc_state->vrr_infopacket did not sync up with the
current state.
It will affect the update_freesync_state_on_stream() does not update
the state correctly.

[How]
Reset the freesync config before get_freesync_config_for_crtc() to
make sure we have the correct new_crtc_state for VRR.
