[Impact]
After resume from suspend, the mini-DP output from ASPEED BMC card
is either blank or mess up.

[Fix]
From upstream 6.11 kernel,

1, a fix of the blank screen after resume:
12c35c5582acb drm/ast: Fix black screen after resume

2, DP detection fix:
0ce91928ec62d drm/ast: astdp: Wake up during connector status detection

3, the patchset refactors the CRTC's mode-setting code:
https://lore.kernel.org/all/20240627153638.8765-1-tzimmermann@suse.de/

[Test]
Tested on hardware by vendor for 10 times of suspend and resume.
The screen is OK.

[Where problems could occur]
It may break ASPEED drm support.
