[PATCH v2 0/4] usb: host: add TPL support to ehci ohci and dwc2

[PATCH v2 0/4] usb: host: add TPL support to ehci ohci and dwc2

[Fabrice Gasnier]

The Target Peripheral List (TPL) support is used to identify targeted
devices during Embedded Host (EH) compliance testing. Add TPL support
setting from device tree on ehci-platform, ohci-platform and dwc2 drivers.
Also document TPL support in DWC2 dt-bindings.

Changes in v2:
- Document TPL support in DWC2 dt-bindings
- Spell TPL and EH
- Add collected ack

Amelie Delaunay (3):
  usb: host: ohci-platform: add TPL support
  usb: host: ehci-platform: add TPL support
  usb: dwc2: host: add TPL support

Fabrice Gasnier (1):
