- Fix IRQ reset for XE LP+ (Gustavo)
- Fix h/vsync_end instead of h/vtotal in VBT (Ville)
- Fix C20 PHY msgbus timeout issues (Gustavo)
- Fix pre-TGL FEC pipe A vs. DDI A mixup (Ville)
- Fix FEC state readout for DP MST (Ville)

DRM subsystem core changes:
- Assume sink supports 8 bpc when DSC is supported (Ankit)
- Add drm_edid_is_digital() helper (Jani)
- Parse source physical address from EDID (Jani)
- Add function to attach CEC without EDID (Jani)
- Reorder connector sysfs/debugfs remove (Ville)
