   12 description: >
   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   Tegra234 has three PHY bricks namely HSIO, NVHS and GBE (Gigabit Ethernet)
   16   each interfacing with 8, 8 and 8 P2U instances respectively.
   17   A P2U instance is a glue logic between Synopsys DesignWare Core PCIe IP's PIPE
   18   interface and PHY of HSIO/NVHS/GBE bricks. Each P2U instance represents one
   19   PCIe lane.
