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. Also new is enabling the TI TCAN1046 PHY as well as Renesas RZ/V2H(P) and RZ/V2N USB3, Mediatek MT8188 HDMI PHY, and the Google Tensor SoC USB PHY driver. That Google support follows the USB driver support for the Google Tensor SoC that was merged too during the Linux 7.0 merge window.
Rockchip meanwhile with the samsung-hdptx driver has added HDMI 2.1 FRL configuration support. This is for dealing with the Samsung HDMI/eDP Transmitter Combo PHY that supports four HDMI 2.1 FIxed Rate Link lanes.
More details on these many changes via the PHY pull.
