Extend the Tegra234 XUSB host binding to cover Tegra264: - Add nvidia,tegra264-xusb compatible string - Document optional USB wake interrupts for Tegra264 - Document Tegra264 PMC wake event to port mapping - Allow up to five IOMMU specifiers for the additional XUSB host stream IDs Signed-off-by: Wayne Chang <redacted> --- V1 -> V2: Property definitions are back at the top level with the widest constraints, The allOf conditional only tightens Tegra234 to interrupts maxItems 9 and iommus maxItems 1. .../bindings/usb/nvidia,tegra234-xusb.yaml | 35 ++++++++++++++++--- 1 file changed, 30 insertions(+), 5 deletions(-)
