DSI display don't come back from resume

• H/W: CHUWI minibook X (Jasperlake Celeron N5100)
• Linux distro: Gentoo
• Kernel: drm-tip as of commit cf3754bc06ab3f7ea3190d9bb4a2600de7655d6c
• WM: sway

On my env suspend/resume is working fine after resolving this issue #5984 (closed) But now display don't come back on resume, stay black(it seems LED backlight is not resumed) suspend/resume works, only display issue

Could I have some way to investigate for the root cause?

I can't find no error on resume in dmesg output. Please see the attached file of full dmesg log.
