- Add missing LNL ALPM AUX wake configuration (Jouni)
- Cx0 PHY state readout and verify fixes (Mika)
- Fix PSR (panel replay) debugfs for MST connectors (Imre)
- Fail HDCP repeater authentication if Type1 device not present (Suraj)
- Ratelimit debug logging in vm_fault_ttm (Nirmoy)
- Use a fake PCH for MTL because south display is not on the PCH (Haridhar)
- Disable DSB for Xe driver for now (José)
- Fix some LNL display register changes (Lucas)
- Fix build on ChromeOS (Paz Zcharya)
- Preserve current shared DPLL for fastsets on Type-C ports (Ville)
- Fix state checker warnings for MG/TC/TBT PLLs (Ville)
- Fix HDCP repeater ctl register value on errors (Jani)
- Allow FBC with CCS modifiers on SKL+ (Ville)
- Fix HDCP GGTT pinning (Ville)
