[PATCH V3 0/3] usb: host: xhci-tegra: Add Tegra264 XHCI support

[Wayne Chang <waynec@nvidia.com>]

Add Tegra264 support to the Tegra XUSB host (xhci-tegra) driver and
its binding, as part of enabling USB host functions on the Tegra264
Jetson AGX Thor platform.

This series was previously posted as part of a single 8-patch series
covering phy, USB host and arm64 DTS changes together [1]. Per review
feedback, it has been split by subsystem so each maintainer can pick
up only what belongs to their tree:

- usb: host: xhci-tegra + its dt-bindings/usb: this series
- phy: tegra: xusb + its dt-bindings/phy: separate series [2], sent
  ahead of this one
- arm64: tegra DTS enablement: separate series, to be sent once the
  binding patches from this series and [2] have landed, since it
  depends on both

Patch 1/3 (dt-bindings: usb) also addresses Krzysztof's V2 review
comments: the iommus entries are now listed individually, and Tegra264
gets its own allOf conditional pinning interrupts to 10 and iommus to 5,
instead of inheriting Tegra234's wider top-level bounds unconstrained.
