# rkcomphy(4)

Rockchip PCIe/USB3/SATA/QSGMII PHY

## NAME

**rkcomphy** – Rockchip PCIe/USB3/SATA/QSGMII PHY

## SYNOPSIS

**rkcomphy\* at fdt?**

## DESCRIPTION

The **rkcomphy** driver controls the combo PIPE PHY integrated on Rockchip RK3528, RK3566/RK3568 and RK3588 SoCs. The PHY supports the PCIe 2.0 (2.5 GT/s and 5 GT/s), USB 3.0 (5 Gbps), SATA (1.5 Gbit/s, 3 Gbit/s and 6 Gbit/s) and QSGMII (1.25 Gbit/s and 5 Gbit/s) protocols. The **rkcomphy** driver does not implement support for QSGMII, and on the RK3528 SoC, only PCIe is supported.
