^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) NVIDIA Tegra194 P2U binding
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Tegra194 has two PHY bricks namely HSIO (High Speed IO) and NVHS (NVIDIA High
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) Speed) each interfacing with 12 and 8 P2U instances respectively.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) A P2U instance is a glue logic between Synopsys DesignWare Core PCIe IP's PIPE
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) interface and PHY of HSIO/NVHS bricks. Each P2U instance represents one PCIe
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) lane.
