• Linux 7.0 Brings Apple Type-C PHY, Snapdragon X2 & Rockchip HDMI 2.1 FRL Additions Ahead of the Linux 7.0 merge window ending this weekend, the PHY updates were merged this week for this next major kernel release. • There are some notable PHY additions particularly for Apple Silicon USB Type-C support as well as additions for Qualcomm’s new Snapdragon X2 laptop SoCs. • For the Qualcomm Snapdragon X2 “Glymur” there is now mainline support for the PCIe Gen4 2-lanes PCIe PHY, DP and eDP (Embedded DisplayPort) PHY, USB UNI PHY support and SMB2370 eUSB2 repeater support. • Also on the Qualcomm side is SC8280xp QMP UFS PHY support, Kaanapali PCIe PHY and QMP PHY support with the Snapdragon 8 Elite Gen 5 SoC, and QCS615 QMP USB3+DP PHY. • Following all the Apple Silicon USB work going upstream in recent kernel releases, the Apple USB Type-C PHY support is now mainline in Linux 7.0. • Another new PHY driver is for the SpacemiT PCIe/combo PHY and K1 USB2.

Article Summaries:

  • Linux 7.0’s merge window added several new PHY drivers, expanding support for modern hardware. Apple Silicon now has mainline USB‑Type‑C PHY support, while Qualcomm’s Snapdragon X2 “Glymur” receives PCIe Gen4, DP/eDP, USB‑UNI, and SMB2370 eUSB2 repeater drivers. Additional Qualcomm PHYs for UFS, PCIe, and USB3+DP on newer SoCs were merged. New drivers also cover SpacemiT PCIe/combo PHY, TI TCAN1046, Renesas USB3 on RZ/V2H(P) and RZ/V2N, Mediatek MT8188 HDMI PHY, and Google Tensor SoC USB PHY. Rockchip’s samsung‑hdptx driver now supports HDMI 2.1 FRL for four‑lane fixed‑rate links.
