16 本文档解释了 PHY 的通用框架和提供的API，以及使用方法。
21 *PHY* 是物理层的缩写，它被用来把设备连接到一个物理媒介，例如USB控制器
22 有一个提供序列化、反序列化、编码、解码和负责获取所需的数据传输速率的 PHY。
23 注意，有些USB控制器内嵌了 PHY 的功能，其它的则使用了一个外置的PHY，此外
24 使用 PHY 的设备还有无线网、以太网、SATA等（控制器）。
26 创建这个框架的目的是将遍布 Linux 内核的 PHY 驱动程序融入到 drivers/phy，
29 该框架仅适用于使用外部 PHY（PHY 功能未嵌入控制器内）的设备。

7 This document explains the Generic PHY Framework along with the APIs provided,
8 and how-to-use.
13 *PHY* is the abbreviation for physical layer. It is used to connect a device
14 to the physical medium e.g., the USB controller has a PHY to provide functions
15 such as serialization, de-serialization, encoding, decoding and is responsible
17 controllers have PHY functionality embedded into it and others use an external
18 PHY. Other peripherals that use PHY include Wireless LAN, Ethernet,
21 The intention of creating this framework is to bring the PHY drivers spread
22 all over the Linux kernel to drivers/phy to increase code re-use and for
