description:
The MediaTek PCI-Express Gen4 S-PHY is capable of data serialization
and de-serialization with 8, 10, 128 or 130 bits (16GT/s) encoding
and decoding, has analog buffers, elastic buffers and mechanisms for
receiver detection.
This PHY supports link rates of 2.5, 5.0, 8.0 and 16.0 GT/s per-lane
in both Root Complex (RC) and End Point (EP) modes, depending on the
chosen port.
The Digital PHY (PHYD) part adheres to the Intel PIPE (PHY Interface
for the PCIe) specification.

title: Qualcomm Nord QMP Quadfurcated PCIe multiple link-mode PHY
maintainers:
- Krishna Chaitanya Chundru <krishna.chundru@oss.qualcomm.com>
description:
The Qualcomm Nord PCIe PHY is a Gen5-capable QMP PCIe PHY composed
of four PHY ports (A/B/C/D). The ports can be combined to support
multiple lane topologies, including x16, x8+x8, x8+x4+x4 and
x8+x4+x2+x2 configurations.
The selected topology is determined by the PCIe link configuration mode
programmed in TCSR registers. Depending on the selected mode, PHY ports
may operate independently or be grouped together to form wider PCIe links.
Each port provides dedicated register space, clocks, resets and power
resources required for PHY operation.

Enable this to support the USB 3.2 PHY on the Aspeed AST2700 SoC.
It supports SuperSpeedPlus Gen2x1 (10 Gbps), SuperSpeed (5 Gbps),
High Speed (480 Mbps), Full Speed (12 Mbps) and Low Speed
(1.5 Mbps), and is paired with the DWC3 USB controller.
