xhci: translate virtual addresses into the bus's address space

2021-02-18T10:56:26+00:00

So far we've been content with passing physical addresses when
configuring memory addresses into XHCI controllers, but not all
platforms have buses with transparent mappings. Specifically the
Raspberry Pi 4 might introduce an offset to memory accesses incoming
from its PCIe port.

Introduce xhci_virt_to_bus() and xhci_bus_to_virt() to cater with these
limitations, and make sure we don't break non DM users.

usb: dwc2: add "u-boot,force-vbus-detection" for stm32

2020-11-22T12:18:20+00:00

On some board, the ID pin is not connected so the B session must be
overridden with "u-boot,force_b_session_valid" but the VBus sensing
must continue to be handle.

To managed it, this patch adds a new DT field
"u-boot,force-vbus-detection" to use with "u-boot,force_b_session_valid"

usb: xhci: add quirks flag to support MediaTek xHCI 0.96

2020-10-01T17:43:05+00:00

There some vendor quirks for MTK xHCI 0.96 host controller:
1. It defines some extra SW scheduling parameters for HW
   to minimize the scheduling effort for synchronous and
   interrupt endpoints. The parameters are put into reserved
   DWs of slot context and endpoint context.
2. Its TDS in  Normal TRB defines a number of packets that
   remains to be transferred for a TD after processing all
   Max packets in all previous TRBs.

usb: xhci: create one unified function to calculate TRB TD remainder

2020-10-01T17:43:05+00:00

xhci versions 1.0 and later report the untransferred data remaining in a
TD a bit differently than older hosts.

We used to have separate functions for these, and needed to check host
version before calling the right function.

Now Mediatek host has an additional quirk on how it uses the TD Size
field for remaining data. To prevent yet another function for calculating
remainder we instead want to make one quirk friendly unified function.

Porting from the Linux:
c840d6ce772d("xhci: create one unified function to calculate TRB TD remainder.")
124c39371114("xhci: use boolean to indicate last trb in td remainder calculation")
