xhci-pci: Allow host runtime PM as default for Intel Meteor Lake xHCI

2022-06-23T14:27:28+00:00

Meteor Lake TCSS(Type-C Subsystem) xHCI needs to be runtime suspended whenever possible to allow the TCSS hardware block to enter D3cold and thus save energy.

xhci-pci: Allow host runtime PM as default for Intel Raptor Lake xHCI

In the same way as Intel Alder Lake TCSS (Type-C Subsystem) the Raptor Lake TCSS xHCI needs to be runtime suspended whenever possible to allow the TCSS hardware block to enter D3cold and thus save energy.

xhci: turn off port power in shutdown

2022-06-23T14:27:28+00:00

If ports are not turned off in shutdown then runtime suspended self-powered USB devices may survive in U3 link state over S5. During subsequent boot, if firmware sends an IPC command to program the port in DISCONNECT state, it will time out, causing significant delay in the boot time. Turning off roothub port power is also recommended in xhci specification 4.19.4 "Port Power" in the additional note.

xhci: Keep interrupt disabled in initialization until host is running.

2022-06-23T14:27:28+00:00

irq is disabled in xhci_quiesce(called by xhci_halt, with bit:2 cleared in USBCMD register), but xhci_run(called by usb_add_hcd) re-enable it. It's possible that you will receive thousands of interrupt requests after initialization for 2.0 roothub. And you will get a lot of warning like, "xHCI dying, ignoring interrupt. Shouldn't IRQs be disabled?". This amount of interrupt requests will cause the entire system to freeze. This problem was first found on a device with ASM2142 host controller on it.

staging: octeon-usb: move driver out of staging

2022-06-21T14:43:37+00:00

The Octeon usb driver has been in staging for a long time and used in Ubiquiti routers for a while now. It's been built and then tested on real hardware with several usb devices and it is proven to be stable and ready to be moved to its proper place in the kernel tree. Move it to drivers/usb/host and adjust its Makefile, Kconfig and defconfig dependencies. Many thanks to the developers who made it happen.
