[PATCH v3 0/2] Add support for the QMP PCIe PHYs in Qualcomm IPQ9650
From: Kathiravan Thirumoorthy
Date: Fri Jul 10 2026 - 13:47:05 EST
Qualcomm's IPQ9650 SoC has 3 Gen3 dual lane and 2 Gen3 single lane
controllers with the QMP PHYs. Unlike the PHYs in the other IPQ SoC,
refgen supply is needed to bringup the PHYs. Both single and dual lane
shares the same HW init sequence. So reuse the tables.
Document the compatible along with refgen supply and add the phy driver
support for it.
