10 - Thierry Reding <treding@nvidia.com>
13 Tegra194 has two PHY bricks namely HSIO (High Speed IO) and NVHS (NVIDIA High
14 Speed) each interfacing with 12 and 8 P2U instances respectively.
15 A P2U instance is a glue logic between Synopsys DesignWare Core PCIe IP's PIPE
16 interface and PHY of HSIO/NVHS bricks. Each P2U instance represents one PCIe
