[PATCH V3 0/4] phy: tegra: xusb: Add Tegra264 support

[Wayne Chang <waynec@nvidia.com>]

Add Tegra264 support to the Tegra XUSB PHY 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:

- phy: tegra: xusb: this series (dt-bindings/phy + drivers/phy/tegra)
- usb: host: xhci-tegra + its dt-bindings/usb: separate series, to
  follow shortly (will reference this series once posted)
- arm64: tegra DTS enablement: separate series, to be sent once both
  of the above have landed, since it depends on both

Patch 1/4 (dt-bindings: phy) now spells out in the commit message why
Tegra264 needs its own compatible string instead of falling back to
nvidia,tegra234-xusb-padctl, per Conor's and Krzysztof's repeated
question on v1/v2.
