NVIDIA Tegra194 P2U binding
|
|
|
|
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.
|
|
|
|
Required properties:
|
|
- compatible: For Tegra19x, must contain "nvidia,tegra194-p2u".
|
|
- reg: Should be the physical address space and length of respective each P2U
|
|
instance.
|
|
- reg-names: Must include the entry "ctl".
|
|
|
|
Required properties for PHY port node:
|
|
- #phy-cells: Defined by generic PHY bindings. Must be 0.
|
|
|
|
Refer to phy/phy-bindings.txt for the generic PHY binding properties.
|
|
|
|
Example:
|
|
|
|
p2u_hsio_0: phy@3e10000 {
|
|
compatible = "nvidia,tegra194-p2u";
|
|
reg = <0x03e10000 0x10000>;
|
|
reg-names = "ctl";
|
|
|
|
#phy-cells = <0>;
|
|
};
