| title: NVIDIA Tegra194 & Tegra234 P2U |
| - Thierry Reding <treding@nvidia.com> |
| Tegra194 has two PHY bricks namely HSIO (High Speed IO) and NVHS (NVIDIA High |
| Speed) each interfacing with 12 and 8 P2U instances respectively. |
| Tegra234 has three PHY bricks namely HSIO, NVHS and GBE (Gigabit Ethernet) |
| each interfacing with 8, 8 and 8 P2U instances respectively. |
| A P2U instance is a glue logic between Synopsys DesignWare Core PCIe IP's PIPE |
| interface and PHY of HSIO/NVHS/GBE bricks. Each P2U instance represents one |
