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。
34 PHY provider是指实现一个或多个 PHY 实例的实体。对于 PHY provider 仅
35 实现单个 PHY 实例的简单情况，框架在 of_phy_simple_xlate 中提供其自己
