The reference-design rail voltages that both sm8550-mtp and the rtwo downstream share are unchanged, but three rails carry board-specific ranges in the Motorola DT / device DTB dump: L11B (panel VDD): 1.20-1.50 V -> 1.23-1.28 V L1E (USB HS phy): fixed 0.88 V -> 0.88-0.912 V L1G (UFS VCCQ): fixed 1.20 V -> 1.144-1.256 V Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QF5HebjUsRaxbW4cBX6HJP
