From: "Chia-Lin Kao (AceLan)" <acelan.kao@canonical.com> BugLink: https://launchpad.net/bugs/2001599 [Impact] On some laptops, the eDP blinking slowly after resuming from S3 [Fix] The series of patches which are in drp-tip(v6.3-rc1) fix the isue https://patchwork.freedesktop.org/series/110693/ 4c0eb35fc103 drm/i915: Improve PPS debugs ed5509d1d451 drm/i915: Fix whitespace 1e47e035bb73 drm/i915: Print the PPS registers using consistent format ba21bb24810f drm/i915: Reject unusable power sequencers d83804f22d85 drm/i915: Extend dual PPS handlind for ICP+ bf38bba3e7d6 drm/i915: Try to use the correct power sequencer intiially on bxt/glk 209074fd5a82 drm/i915: Generalize the PPS vlv_pipe_check() stuff 3f9ffce5765d drm/i915: Do panel VBT init early if the VBT declares an explicit panel type f70f8153e364 drm/i915: Introduce intel_panel_init_alloc() [Test] ODM and I confirmed the issue is fixed after the patches have been applied. [Where problems may occur] This series of patches fixes a dedicate issue and change the power sequence for the eDP panel. eDP panel may stay blank if the rules are wrong. OEM kernel has carried this series of patches since early Feb., we didn't get any report about the panel issue.
