I am also not sure you want to declare the USB3 PHY in k3.dtsi. I think it should be defined at the board level, as other boards than the k3 Pico ITX might decide to keep this controller as USB 2 only and use the combo PHY for PCIe. -- Aurelien Jarno GPG: 4096R/1DDD8C9B aurelien@aurel32.net http://aurel32.net _______________________________________________ linux-riscv mailing list linux-riscv@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-riscv ^ permalink raw reply [flat|nested] 8+ messages in thread

Are you saying that the hardware advertises support for INTx, but spacemit hasn't provided a driver that uses it? Is there a way to let the driver know to not try setting up legacy interrupts then?
