description: >
Tegra194 has two PHY bricks namely HSIO (High Speed IO) and NVHS (NVIDIA High
Speed) each interfacing with 12 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 bricks. Each P2U instance represents one PCIe
lane.
