1 NVIDIA Tegra194 P2U binding
3 Tegra194 has two PHY bricks namely HSIO (High Speed IO) and NVHS (NVIDIA High
4 Speed) each interfacing with 12 and 8 P2U instances respectively.
5 A P2U instance is a glue logic between Synopsys DesignWare Core PCIe IP's PIPE
6 interface and PHY of HSIO/NVHS bricks. Each P2U instance represents one PCIe
10 - compatible: For Tegra19x, must contain "nvidia,tegra194-p2u".
11 - reg: Should be the physical address space and length of respective each P2U
13 - reg-names: Must include the entry "ctl".
15 Required properties for PHY port node:
16 - #phy-cells: Defined by generic PHY bindings. Must be 0.
18 Refer to phy/phy-bindings.txt for the generic PHY binding properties.
